Battery Life And Capacity

and CapacityA new chemical trick for creating nanostructured fabrics should help increase the section and reliability of electric cars and lead to better batteries that should help stabilize the power grid. Researchers at the Pacific Northwest Local Science department PNNL in Richland, WA, have developed the technique, which can turn a potential electrode fabric that cannot normally shop electricity into one that stores more life than similar battery fabrics already on the market. In work published within the journal Nano Letters, the PNNL researchers display that paraffin wax and oleic acid encourages the growth of platelike nanostructures of lithium-manganese phosphate. These nanoplates are mini and thin, allowing electrons and ions atoms or molecules with a positive or negative charge to move in and out of them easily. This turns the material--which ordinarily does not work like a battery fabric due to the fact that of its very poor conductivity--into one that stores large amounts of electricity.

When the researchers measured the performance regarding the material, they discovered that it should shop 10 percent more life than the theoretical maximum life capacity of a comparable commercial electrode material--lithium-iron phosphate, that is used in power tools and some hybrid and electric vehicles. The approach should reveal the door to creating use of a large section of candidate battery fabrics that are now limited by their ability to conduct electricity and lithium ions. Studies within the region has reached the spot at which most regarding the battery fabrics left to be studied have bad conductivity, says Daiwon Choi, an life fabrics researcher at PNNL. The new method gives a simple method to increase their conductivity. He says the method should also be compatible with conventional battery-manufacturing techniques.

Both lithium-iron phosphate and lithium-manganese phosphate are attractive at battery electrodes due to the fact that they hold a stable atomic structure. This crystalline structure--called olivine--is distant more stable than the crystal structure of electrode fabrics used in IBM Laptop Battery for example IBM 08K8198 Battery and IBM 08K8197 Battery. Like a result, olivine fabrics can final many detailed than the 3 years that cell-phone battery fabrics typically last. Some manufacturers claim that lithium-iron phosphate batteries should final for over 30,000 done charge and discharge cycles without losing many of their capacity to shop energy--enough for the battery to final 50 years, Choi says. In theory, lithium-manganese phosphate should final for a similar many cycles, due to the fact that it has a similar crystalline structure.

But it has the added advantage of potentially being can shop 20 percent more life than lithium-iron phosphate, since it operates at a higher voltage. However, it was particularly hard to modify lithium-manganese phosphate to overcome the fact that it's an electrical insulator. Previous attempts have compulsory processing precursor fabrics in a liquid solution prior to creating solid battery materials--a process that is too expensive for commercial production. The new method developed at PNNL eliminates this separate liquid-processing step, simplifying the process and creating it compatible with existing manufacturing techniques. To get ready the material, the researchers combine chemical precursors with paraffin wax and oleic acid.

The wax and acid work together to cause the precursor fabrics to shape crystals of a well-controlled volume and shape without clumping up. The wax liquefies at the high temperatures used to process the fabric and acts like a solvent that replaces the separate liquid processing step used in earlier research. So far, the fabric can only be charged at little rates consequently it delivers power fast enough for many applications. Choi says one regarding the next steps is to develop an improved process for coating the nanoplates with carbon, which should improve conductivity. Although lithium-manganese phosphate is attractive due to the fact that it stores more life than lithium-iron phosphate, most take up a relatively large no.

of volume compared to other categories of electrodes for lithium ion batteries. Jeff Dahn, professor of physics and chemistry at Dalhousie University, says this should ultimately make them more attractive for stationary applications--such as storing power on the electricity grid to help smooth out variability from renewable sources--than for electric vehicles.

How One Tiny Business Trumped Hurricane Katrina With Help From The Regional High School

August 2005 had been a good month for me, as I marked 10 years in business. All month long, the mood was festive and upbeat, and I was pleased at how well the business was going and excited regarding the future. But suddenly, my entire world was turned upside below and inside out when the massive storm struck and did its horrible damage. On the day Katrina hit the Gulf Coast, I was supposed to be filming my 2nd exercise DVD in New Orleans - but the only filming done that day was by the news media, recording the Katrina disaster as it grew ever more ominous and life-threatening. My family and I were safe, possessing evacuated to my high school physics Florida.

But we were filled with fear and anxiety about what was going to happen to our home, and to homes of our friends. we wondered if we were even going to hold a home to leave return to. From Florida, we headed for Houston, where my husband's job called him. We stayed in Houston for one month, during which time I could not even locate out about - many fewer do anything about -- my business, which I feared may leave below with so many other hopes, dreams and physical properties return home. When we were can return, finally, we were relieved and grateful to learn that we only wanted to have our roof replaced and simple up some minor inside damage.

The home front was going to be all right -- but my business wasn't faring as well. Everyone's top priority was to take like of our properties and to help others who were struggling. With all the trees below and dangerous, filthy debris everywhere, there was no method to even take a brisk walk to help shake off the blues. All any of us should do, day subsequent to endless day, was to work at cleaning up the unbelievable mess. My son's college reopened, so he was gone all day.

my husband was still in Houston. and I was trapped in a nightmare where each effort I created to move forward was met with a resounding No way! I did display up at my studio, but it was wasted effort, since I was usually the only one there. My clients did not have the time, the life or the motivation to hold up with their workouts during this troubled time. I was frustrated beyond words, and depression began to settle in and drag me below into its numbing clutches. but I also am very stubborn when I trust in what I'm doing.

and my belief in my business was strong. There basically was no method I was going to let it leave below without a fight. With my family's blessing, I began to take cash out of our home funds to pay rent and bills for the business. Thankfully, they shared my belief that sometime within the near future things should be salvaged, turned around and should get better. but there was no other choice, other than the unacceptable two of seeing my business fall apart, fail and disappear.

and I am one stubborn businesswoman when the cause is just and failure unacceptable. One day I just set aside the mop, the broom, the buckets for debris, the work gloves and the stained, tattered coveralls, and decided that is all the cleaning up I was going to do. If the carpets stayed muddy for a while longer, well, that wasn't going to be the end regarding the world. But thinking about losing my business felt like exactly that - and I basically wasn't going to have it. First, I decided to leave over the script that I had planned to use for the 2nd DVD, editing it and revising it to be a tighter presentation.

That exercise refreshed my focus and sense of purpose for the business and I was inspired to take it to next position of intensity, writing another script called focused on an alternate kind of exercise. That writing went very quickly, as well, as plans - long shelved in favor regarding the more immediate demands of hurricane simple up - burst through to my consciousness. Subsequent to that, I wrote a script for the next level. and subsequent to that, I began to pull together thoughts and exercises for an aerobic DVD. Suddenly, from someone below within the dumps, battling depression and a growing sense of futility, I was a home afire once again, with renewed purpose and direction.

with no clients coming to studio, with everyone's spirits at fewest badly bruised, if not crushed, how was that going to happen? And where should the funds return from to pay for the filming? Not ever mind. The disruption of daily life should end, some day. people should return to more normal routines. and when the time was right I should already have scripts written for whole new set of exercise DVDs. One day my son came home from college together with the news that his press instructor had provided the okay to film at his school, saying it should be a good project for the children to work on.

I certainly wasn't expecting a professional result from the kids, but was nevertheless grateful for the release and thought that at the very least, it should let me to do a practice sprint through. 3 weeks later we started to film, and the position of professionalism these students should deliver was stunning. The result was so good, in fact, that I grow to a mentor for the Fontainebleau High College Press Program and they agreed to film all the DVDs I had written. This was good skills development for them and a huge break for me. Between the months of January and Shall 2006 we were can film 5 DVDs plus a redo of our original DVD.

To thank the school, I now release them a percentage of each video sold to help help the press center. I wanted to tell this story to display that while Katrina was a devastating event, with a profound and horrible impact on many lives, it also ignited the spark of all that is greatest in humankind. spirits that will not be smothered, hopes that will not be destroyed, determination that shall guarantee triumph, and the pretty symbiosis of people working together for the greatest interests of all. My business thrives again, today. and the Press Program at Fontainebleau High College thrives, as well.

And the healing and growth continue.

Defensive Mechanism Of S.s

Defensive Mechanism of S. Introduction The primary functions of a circuit breaker are interrupting brief circuit current, carrying normal currents, switching ON and OFF normal loads, and providing compulsory insulating between live components and earthed parts. The maintenance problems involved with bulk oil circuit breakers were immense. Minimum Oil technology had replaced bulk oil technology during 1950's. Similarly the space -blast technology was developed for obtaining higher performance characteristics.

However, the space -blast breakers are barely expensive, and their procedure and maintenance cumbersome. Hence and need was felt during 1960's for reduced maintenance. SF6was first obtained from Fluorine and Sulphur in 1900 by M or s. Behavior of SF6in Electrical field was studied by M or s. COOPER in 4936 known for over 3 decades, perfection on commercial exploitation was attained during 1960's.

This development created it likely for SF6gas at little compression to be used in BIN circuit breakers for insulating and are' quenching purposes, Some regarding the outstanding properties of SF seven gas which make its use necessary in EHV circuit. Electro negative nature 4. High dielectric strength 5. Special are quenching property 6. Chemical and thermal stability 7.

Good Thermal conductivity 8. Non-Flammability The combined electrical, physical, chemical and thermal properties of SF6offer the following outstanding features when used in force circuit breaker. Simplified creation 5. High degree of reliability 6. Switching of capacitive currents without restrike 7.

Very tow noise position 8. Easy for installation 10. Maintenance free service 2. Properties of Sulphur Hexafluoride SF6 a Physical properties: SF6is a colorless, odorless and non-flammable gas. The fluorine atoms are placed at the corners of a standard octa-hedran with the sulphur atom centrally placed at a distance of 1.

The bonds are predominantly covalent and the dissociation equation is SF6 -- SF5+ F The decomposition potential is 15. SF6gas is a very heavy gas and its density is approximately 5. It is more compressible than space and follows the law of thorough gases. be Electrical properties: The di-electric strength of SF6gas is 4 times that of space at atmospheric compression and is only marginally reduced by the presence of space as impurity. The dielectric strength increases with increasing pressure.

At a compression of 3 bars, the dielectric strength becomes equal to that transformer oil. The volume and electro negative nature molecule explain this strength. The molecule gives a huge electron collision diameter. This conclusions in capture of electrons preventing them from attaining sufficient life to make additional. current carrying particles.

SF6moiecuie also has the ability to save life within the vibrational and electronic' grades regarding the molecule there by forming stable ions of little mobility. The dielectric strength of SF6remains unaltered over a large section of frequencies. since SF6has no dipole moment, the dielectric constant does not vary with frequency. 30c and atmospheric compression the dielectric constant is 1. 00191 and loss angle is 3 x 10-7.

The dielectric properties of SF6remain unchanged even at little temperatures. Unlike solid insulation fabrics an electrical breakdown in SF seven gas does not result in permanent deterioration of its properties. Break below in all filled tools shall result in enormous increased of compression due to gas formation but such hazards don't ever exist within the case of SF6filled equipment. c Arc quenching properties: The ability to quench arc is special to SF 6. This conclusions within the high dielectric strength regarding the gas and the very rapid recovery of dielectric strength subsequent to arcing occurs.

SF6is approximately 100 times more effective in this respect than space below similar conditions. The little arc-time constant and its capacity to absorb free electrons due to electro negative nature creates it an great moderate for arc interruption. The complex molecular motion of SF6enables it to absorb electric life and shape stable negative ions. Its tendency to shape negative ion around current zero conclusions within the fast disappearance of electrons liberated during arcing. Unlike oil, arcing in SF6will make no carbon deposits or carbon tracking.

The electro-negative property of SF6may be due to multiple factors, within its huge collision diameter. If stray electron electric field shall be absorbed prior to they attain sufficient life to make more current carrying particles though collision, the breakdown shall be slowed or even stopped. The huge collision diameter of SF6molecule assists in capturing these electrons. life shall be stored within the vibration grades regarding the SF6atom, forming stable negative ions of little mobility. Thus the gas is electronegative in nature and shows.

good electron binding capacity. Hence SF6gas displays splendid arc-extinguishing performance. The arc time constant is directly proportional to radius of arc creates it likely to have huge many breakings at full capacity regarding the breaker. The characteristic curve regarding the arc is such that the extinction force be low. In a typical case where the extinction force was regarding the order of 20 KW for an SF6breaker, the corresponding cost of an space blast breaker was in hundreds of KW.

Some ion formation process with SF6are? Resonance capture? SF6+ e - SF6 - SF5-+ F Positive ion formation? SF6+ e - SF6+ + 2e -SF5-+ F + 2e- Excitation and amp; dissociation? SF6+ e - SF6- + e -SF5-+ F + e Positive and amp; negative ion formation: SF + e - SF6- + e -SF5+ F -+ e d Heat Transfer characteristics: SF6has great heat transfer characteristic, an important criterion for gaseous dielectric in force applications. The higher molecular mass together with little gaseous viscosity of SF6enables it to transfer heat by convention more effectively than the common gases. The co-efficient of heat transfer of SF6is approximately 2. 5 tip1es that of space below the similar to conditions. Hence when the breaker is energized, the heat rise small.

e Large heat range? SF6in the gaseous state follows the necessary gas laws fairly closely. Consequently the compression change is only moderate for a considerable change in temperature. The little sublimation points of SF6 assures greater dielectric strength even at little heat the liquification heat is 270C at a compression of 12 Kg or sq. Hence no heater is necessary. f Toxity? SF6is a non-toxic gas and produces no poisonous effect on person body.

But the decomposition products produced by the discharge SF4, SF2, S2, F2etc. These products are minimized by controlling of moisture within the interrupter and by absorbing the decomposition products by synthetic zeolite. g Chemical and Thermal Stability: SF6gas is inert and it is one regarding the fewest reactive substance known below normal operating conditions. It should be heated in quartz to 5000C without below going any decomposition. SF6does not react with water, acids and alkalis.

Tests conducted have shown practically no corrosion for different metals exposed to SF6 h Different constants? Some regarding the outstanding properties of SF6which creates it necessary for high voltage force applications are: Molecular weight. 05 Sublimation spot at two atm. 9C Density of gas at 21. 139 Viscosity liquid at 13. 0157 Critical heat etc.

80 Critical compression bars. 772 Critical volume cu. 356 Dielectric strength reI N2 = al at 50 Hs -1. 5 Dielectric constant at 25C 1atm. 002049 Thermal conductivity at 30C, Cal or Sec.

Breakdown phenomenon in SF6: Breakdown in gases takes location when the free electrons gain sufficient kinetic life Below the influence of an electric field and collide with neutral gas molecules liberating electrons from their outer shells. A chain reaction like this conclusions in an electron avalanche. Within the case of electro-negative gases like SF6this mechanism is slightly modified. The free electrons get attached to molecules forming negative ions. This negative ions are too massive to make collisional ionization.

This attachment represents an effective method of removing electrons which should have otherwise contributed to an electron avalanche. This critical behaviors gives rise to very high dielectric strength for electronegative gases. The breakdown voltage of an electro-negative gas in a uniform field is a simple function regarding the product of compression and spacing. the breakdown characteristics in non-uniform fields shall be different due to the fact that ionization should be primary aimed locally due to presence of regions of high stress. This is the corona effect.

This should be due to surface roughness, sharp comers, floating conducting or semi-conducting particles. In SF6equipments special like is taken to make sure that that such sharp points don't ever exist within the breaker such that a fairly uniform field distribution shall be achieved. Principles of interruption with SF6: Techniques employed for interruption with SF6can be classified into two? a Double compression system. be Lone compression system. The latter shall be distant classified as double flow fixed nozzle and lone flow series piston breakers.

a Double compression system: The functions of insulation and interruption are performed in separate chambers. SF6at a compression of 14 Kg or sq. is stored in an above compression chamber. This is used for quenching the are SF6at little compression 2. When the contacts separate below fault, gas at high compression is forced into the arcing region and then it follows in to little compression region.

The gas thus exhausted in to little compression region is compressed repeatedly and returned to high compression reservoir. The arcing takes location between the arcing tip and arcing ring thus relieving the contact region from the stresses of arc. A filter with actual alumna is kept at the intake regarding the compressor such that all the decomposition products of gas shall be absorbed prior to re-circulating in to system. A thermostatically controlled heating system shall be provided within the high compression reservoir to prevent condensation of gas at little temperature. be Lone compression system? In this case SF6at little compression 4 to 6.

gives the insulation and the life for interruption. The breaker chamber consists regarding the fixed and moving contacts, and the piston arrangement within the puffer kind fixed contact. As the moving contact separates below fault, the piston moves forward with high speed. This compresses the SF seven inside the hallow fixed contact and forces the gas into the arc resulting in quenching. The force with which the gas should be blast depends on the creation regarding the piston arrangement and the life regarding the manage mechanism.

A distant improvement is the Magnetic puffer kind breakers where the operating force on the moving contact rod is increased, by magnetic repulsive force. The brief circuit current is passed through a set of coils fixed on the help regarding the moving contact fed. A secondary brief circuit ring is positioned and magnetically coupled with primary winding. This ring acts as piston as well. This interaction between the.

3 fields produces a repulsive force and it pushes the moving contact rod forward. The addition of this simple magnetic drive mechanism improves the interrupting capabilities regarding the breaker. The lone compression system has an inherent advantage of simplicity in construction. It wants no more compressor as compulsory in double compression system. The manufacturing cost of puffer kind tools is lower.

Construction: The arc extinguishing system employs a synchronized double flow lone compression puffer kind design. This leads to a simple construction. The SF seven circuit breaker mainly comprises regarding the following: 1. Base tube and mechanism container 3. Space compressor electro-hydraulic operating mechanism 1.

Movable Cylinder Puffer cylinder 2. Gas Trapped in prior to compression 7. Compressed gas between two and amp; six 8. The arc-being extinguished by puffer action 5. Breaker Pole: The primary functions of a circuit breaker are carried out of breaker pole.

The breaker pole consists of interrupter unit and help insulator. The interrupter unit consists of fixed contact tube, book tube, moving contact tube, puffer or blast cylinder and piston. The fixed contact tube is connected to top terminal via. The book tube is fastened to decreased terminal. The other ends regarding the fixed contact tube and book tube which are subjected to arcing during the arc interruption are provided with arc quenching nozzles.

the nozzles are created up of graphite fabrics which keeps the contact wear to minimum. The moving contact tube consists of spring loaded finger contacts arranged within the shape of a ring. The front end regarding the moving contact tube is provided with an arc resistance insulating ring and arcing ring of high arc resistant fabrics The blast cylinder that is created up of high arc resistant insulating fabric and the moving contact tube are rigidly coupled to each other and connected to operating rod within the supporting insulator. The blast piston that is created up of aluminum is fastened to decreased terminal pad. The fixed contact tube, book tube, moving contact tube, blast cylinder and blast piston are all housed inside a porcelain, insulator.

When the circuit breaker is in close position current flows from top terminal to bottom terminal through contact support, fixed contact tube, moving contact tube and book tube. The help insulator apart from supporting the interrupter unit give insulation between live components and earthed parts. It houses the operating rod insulated, one end of that is connected to interrupter unit and the other end is connected to mechanism. Base Tube mechanism box: The base tube which supports the breaker pole and the mechanism container acts like a regional space reservoirs. The mechanism container enclosed electromagnetic valve, closing coil, travels coil and operating cylinder.

Decreased mechanism case encloses the done lever system to transmit the procedure force from the mechanism container to breaker pole. Control Unit? This accommodates the gas compression switches, gas density detector, gas compression gauge, space compression gauge, space valve heater, auxiliary relays, terminal blocks, etc. for electrical and pneumatic manage and monitoring regarding the breaker. The manage devices regarding the space and SF6gas processes are common for 4 poles regarding the breaker. Compress Since the operating life requirement is greater the MOCBS neither space compressor or electro-hydraulic operating mechanism is used.

The principle of Arc extinction: When the circuit breaker is in closed position the moving contact assembly bridges the fixed contact tube and the book tube. When an opening procedure is initiated, the blast cylinder moves towards the stationary blast piston such that the SF6gas within the blast cylinder is compressed to a compression compulsory to quench the arc. The gas compressed during the above process is released only when the contacts are separated with moving contact assembly acting like a slide valve. At the instant of contact separation, arc strikes between the front end regarding the arc quenching nozzle regarding the fixed contact tube and the arcing ring regarding the moving contact tube. The compressed gas within the blast cylinder is released within the break radically as the contacts are separated.

As the moving contact assembly moves further, the arc between the front end regarding the fixed contact nozzle and the arcing ring regarding the moving contact is transferred from the arcing ring regarding the moving contacts of nozzle regarding the book tube, by gas jet and its own electrodynamics forces. the arc is distant elongated by the gas flow axially into the nozzles and well-being extinguished. While the arc is being interrupted, the blast cylinder that is created up of arc resistant insulating fabric enclosed the arc quenching assembly, there by protecting the porcelain insulator from arcing effects. Subsequent to arc extinction, the moving contact assembly and blast is free of any components regarding the chamber which shall hold a bridging effect or influence the electric field distributor. Procedure principles: 7.

Opening operation: When the travels coil is energized, the space of pilot valve is filled with compressed space and the charging valve moves to right. The space within the operating cylinder is filled with compressed space from the space received and the operating piston is rapidly driven to left. the operating rod connected to operating piston is pulled within the opening direction to drive the puffer cylinder at the high velocity through the insulated operating rod within the supporting insulator. the SF6gas within the puffer cylinder is compressed and the SF6gas blast extinguishes the arc generated between the moving and stationary contacts. Simultaneous with the opening operation, the cam rotates and causes the electromagnet valve to return to its original position.

Like a result, compressed space within the space of pilot valve is exhausted into atmosphere and the charging valve is reset to original piston. As the reveal state is retained by the link mechanism attached to end regarding the operating piston. Closing operation: When the closing coil is energized, the arc nature is created to rotate causing the hook to be disengaged. Thus the sector line rotates to release the roller and the operating piston is driven within the closing direction by the force regarding the closing spring, upon completion of closing, the link mechanism is held in a state to be ready for the subsequent opening operation. Caution? When operating the breaker observes the following: I Hold correct SF6gas compression and operating space compression as specified.

3 Operate the stop valves properly. 4 Don't ever let ingress of moisture and powder into the SF6gas supplying point. 5 Don't ever push the gas piping and space piping with any object. six Don't ever damage the gasket and seal face on the leakage tight joint within the gas and space system. seven When opening the circuit breaker by the manual handle.

a confirm that the primary circuit is not energized. be Be sure to turn off the manage force supply. c Confirm that compressed space in receivers is released. d Confirm that manual operating rod and handle are removed prior to changing the receiver with compressed air. 7 Don't ever operate any component other than the manual operating handle prior to filling SF6gas at the rated pressure.

Don't ever fill compressed space prior to filling SF6gas. 8 When checking interior components of interrupter, blow space into the system for sufficiently long time and confirm that sufficient supply of space is available prior to starting any work. Gas Leak Detection: If the gas leaks through any point, this can result in reduction of compression and consequent loss of insulation properties Gas Leak detection is done with the help of a halogen torch kind detector. The detector works on the principle that SF6absorbs a sure many electron when passed through an atmosphere where free electrons flow. The free electrons are generated with within the sector by a mini radio active source within the presence of a carrier gas.

these electrons are collected at the detector anode and release a mini base line current that is amplified. When the probe regarding the detector is kept near the joints regarding the SF6filled tools and if SF6leaks out there shall be variation in amplified valve of current due to electron absorption by SF6. The variation shall be directly calibrated to indicate the magnitude regarding the leak. Detention of presence of conducting particles: This is done by conducting a dielectric test when the test voltage is applied there shall be an internal corona if metallic particle or sharp comers are present. The presence of internal discharges is located with the help of an ultrasonic detector that is very sensitive in detecting noise due to internal corona.

The sector translates the ultrasonic vibrations into audible frequencies and directly indicates the intensity of sound in decibels. The probe is pressed firmly against the grounded enclosure tube while the conductor is energized at varying AC I DC voltage. If the noise disappears at little voltage, appears at some intermediate voltage and the intensity continues to increase, it is sure that the noise is due to internal corona. It has also been observed that in some cases the mini sharp potty branched in parts of high dielectric stress get burnt or the particles driven to little stress areas. The effect of conducting particles on the break below strength of SF6is more serious for force frequency voltage test than for impulses voltage.

Performance of SF6Breaker: SF6gas circuit breaker combines the advantageous features minimum oil and space blast breakers and exhibits a many more advantages over both. two It is likely to have huge many breaking operations near full breaking capacity with out any undue wear. 3 Due to the fact that regarding the fast recovery of dielectric strength throughout the parting contacts during interruption. a These breakers are restrict free while switching of capacitive currents. be These breakers are incentive to brief time faults and are capable of breaking at every high values of RRRV and c These breakers are suitable for multi-short re closing with out any reduction in breaking capacity 4 There is no necessity to change any components within the breaking chamber even subsequent to a period many times years of service within the actual system.

This means that there exists practically no difficulty of maintenance for SF6breakers. 5 The procedure is noiseless since the gas is used in a closed circuit. There shall be no discharge of arc products into atmosphere. six Puffer kind breakers are autonomous and independent due to the fact that no auxiliary tools is required. seven Fire hazards are eliminated.

RELAY A relay is an electrical switch that opens and closes below the manage of another electric circuit. Within the original form, the switch is operated by an electromagnet to reveal or close one or many sets of contacts. Procedure When a current flows through the coil, the resulting magnetic field attracts an armature that is mechanically linked to a moving contact. The movement neither creates or breaks a connection with a fixed contact. When the current to coil is switched off, the armature is returned by a force approximately 1/2 as tough as the magnetic force to its relaxed position.

Usually this is a spring, but gravity shall also be used commonly in non-residential motor starters. Most relays are manufactured to operate quickly. In a little voltage application, this is to reduce noise. In an above voltage or high current application, this is to reduce arcing. If the coil is energized with DC, a diode is frequently installed throughout the coil, to dissipate the life from the collapsing magnetic field at deactivation, which should otherwise generate a spike of voltage and may cause damage to circuit components.

Some automotive relays already with that diode inside the relay case. Alternatively a contact protection network, consisting of a capacitor and resistor in series, shall absorb the surge. If the coil is drafted to be energized with AC, a mini copper ring shall be crimped to end regarding the solenoid. This shading ring creates a mini out-of-phase current, which increases the minimum pull on the armature during the AC cycle. By analogy with the functions regarding the original electromagnetic device, a solid-state relay is created with a thyristor or other solid-state switching device.

To achieve electrical isolation an optocoupler shall be used that is a light emitting diode LED coupled with a photo transistor. Categories of relay Latching relay Reed relay Mercury-wetted relay Polarized relay Motor tool relay Contactor relay Solid state contactor relay Buchholz relay Forced-guided contacts relay Solid-state relay Overload protection relay Pole and amp; Throw The following categories of relays are commonly encountered: SPST - Lone Pole Lone Throw. These have 3 terminals which shall be connected or disconnected. Within 3 for the coil, such a relay has 4 terminals in total. It is ambiguous whether the pole is normally reveal or normally closed.

The terminology SPNO and SPNC is sometimes used to resolve the ambiguity. SPDT - Lone Pole Double Throw. A common terminal connects to neither of 3 others. Within 3 for the coil, such a relay has 5 terminals in total. DPST - Double Pole Lone Throw.

These have 3 pairs of terminals. Equivalent to 3 SPST switches or relays actuated by a lone coil. Within 3 for the coil, such a relay has six terminals in total. It is ambiguous whether the poles are normally open, normally closed, or two of each. DPDT - Double Pole Double Throw.

These have 3 rows of change-over terminals. Equivalent to 3 SPDT switches or relays actuated by a lone coil. Such a relay has eight terminals, within the coil. QPDT - Quadruple Pole Double Throw. Many times referred to as Quad Pole Double Throw, or 4PDT.

These have 4 rows of change-over terminals. Equivalent to 4 SPDT switches or relays actuated by a lone coil, or 3 DPDT relays. In total, fourteen terminals within the coil. Protective relay Overcurrent rela Distance relay SURGE ARRESTERS AND INSULATION CO-ORDINATION I. Introduction: Electrical processes by nature involve 3 forms of protection over current and over voltage since over current protection of electrical equipment's are well known to all, it is not elaborated here.

Over voltage protection on the other hand, remains a relatively new subject to many engineers. Most categories of protection equally compulsory for safe system operation. The importance of over voltage protection for a force system can not be over emphasized. Primary tools failures, expensive repairs, personnel well-being and plant below time are sure consequences of inadequate protection from voltage surges. Surge arresters are drafted to limit dangerous system over voltages.

Whether lighting-or System- produced-to safe values when they occur on force systems. An arresters is a voltage limiting device. The functions are to discharge life associated with an procedure over voltage condition, limit and interruption the force fellow current that follows the transient current through the arresters and return to an insulating state prepared for the next over voltage occurrence. In performing its voltage limiting function, sure protective characteristics regarding the arrester should be coordinated with the prevailing insulation grades on the system being protected. Insulation is a simple factor that should be thought about within the application of arresters on a system.

Insulation co-ordination is only a mini component regarding the over all subject of arrester application. Multiple other factors should also be thought about by the engineer when selecting surge protection. The location regarding the arresters, the inter-connection of ground leads, the insulation position regarding the protected tools and the rating regarding the surge arresters are important in protecting tools from harmful over voltage. Surge Arrester operation: The simple procedure of a surge arrester is single. In its noffi1al state, an arrester should act as an insulator.

When an above voltage surge occurs. The arrester should cease to be an insulator and should turn into a brief to-ground-in million thus of a second. The procedure regarding the highest many widely used kind of surge arresters the value, kind of arrester is dealt with. Other categories of arresters, for example expulsion arresters and line Oxide arresters Gapless arresters are neither on the decline or too new for a general discussion at this time. The active elements of a valve kind arrester are the spark gap and the valve block.

these are housed in a porcelain shell for atmospheric protection and external insulation. The gap assembly consists of a many in-series space gaps with sufficient dielectric strength to withstand the highest force frequency on the system. During severe over voltage conditions, the gap should always, breakdown at a voltage position some what below the insulation withstand voltage position regarding the tools it is protecting, other wise tools damage and or plant below time shall result. the gap that is why serves as the switch which turns on the arrester. the voltage position at which the arrester goes from the passive insulating to active conducting state, is called the spark over voltage.

The valve block controls what happens subsequent to the arrester was turned on. If only a gap is used, once a surge was diverted to ground, a dead brief circuit exists between line and ground and the 50 hertz-system life tries to flow to ground causing a fuse, re-closer or breaker to operate to interrupt the system fault current. The valve element does exactly as its name implies. It conducts when surge current is flowing and it ceases to conduct when 50 Hz line current begins to flow. the valve block is can do this due to the fact that It is created of a non-linear resistance material, silicon carbide.

The valve block offers a very high resistance to 50 Hz current while displaying a little resistance to surge current. In addition, it also consumes the surge life passes through it. Spark over and discharge voltage are the 3 protective characteristics of an arrester which are used in calculating margins of protection when studying insulation co-ordination. These protective characteristics are published by arrester manufacturers. Arrester Classification? There exists 3 classifications of surge arresters used for over voltage protection in a system.

Distribution Type: The arresters are generally used in distribution system for tools protection. Standards distribution arresters are used for protecting oil. Insulated distribution transformers, these arresters are also used as line entrance arresters, for 11KV and 22KV lines. They can be the lowest in cost. Intermediate Type? These units cost approximately 3 or 3 times as many as equivalent distribution units.

For this, the arrester offers decreased maximum spark over and discharge voltage characteristics that afford a greater margin of protection plus the capability of discharging huge surge levels. These arresters also hold a compression relief system to safely vent internal compression if the unit falls prior to the porcelains shell has a chance to rupture. These arresters are used for the L. protection of Force transformers in sub-transmission sub-station i. 110 or 33 or 22 or 11KV and 66 or 22 or 11KV sub-station.

Station Type: These arresters release the greatest protective characteristics and the highest thermal capability but they cost about twice as many as equivalent intermediate units. Like intermediate arresters, station arresters hold a pressure-relief system to safely vent internal compression if the unit fails prior to a porcelain shell has a chance to rupture. These arresters are generally used in 230KV, 110KV and 66KV systems. Basic insulation level: Simple Impulse Insulation Position BIL is the voltage position that tools insulation is capable of withstanding without sustaining damage. The voltage withstand of insulation is function of time.

Inorder to establish volt-time impulse insulation grades of transformers standard impulse tests standard voltage withstand tests are conducted on selected units as kind test. Transformers are subjected to impulse voltage tests at rated BIL and a chopped wave test 15% above BIL. A steep front - of wave test 65% above BIL shall also be performed on some units. A curve plotted through these 3 points defines the minimum insulation withstand curve for insulation co-ordination Fig. 3 The true withstand position for the transformer lies above the plotted curve.

Surge arrester application: With an understanding of how an arrester performs its functions and a knowledge of tools insulation, we can now move into the application region and think about the multiple factors that comprise surge arrester application as it relates to over voltage protection of transformers, The selection of surge arresters merit are carefully considered. Different factors need to be taken into account sequential to arrive at a reliable and at the similar to time economical means of protection. The important points are: i Selection of rated voltage. ii Selection regarding to standards, codes, recommendations for insulation coordination. i Arrester rating? The voltage rating of an arrester is defined as the highest 50 Hz voltage at which the arrester is drafted to operate and reseal effectively subsequent to a surge has passed.

Due to the fact that regarding the system grounding and connection, this, voltage is typically higher than the phase to ground voltage or on the well phases shall increase temporarily and it depends upon the earthing factor or the system. The selection of an arrester voltage rating for station depends upon grounding system connection and system voltage rating. Also the voltage impressed throughout an arrester during a surge discharge is directly proportional to arrester voltage rating that is, a 10,000 Amps surge produces a higher discharge voltage if it is flowed through a 10KV arrester than it does flowed through a 9KV arrester generally it is desirable from the stand spot of tools protection to select the lowest voltage rating for the application. ii Arrester location: Surge arresters should always be located as close as likely to terminals regarding the tools protected. Within the case of transformer protection, mounting the arresters directly on the transformer is the greatest of insurance.

An appreciable distance between the surge arrester, and the protected tools reduces protection, afforded by the arresters and also increases the voltage impressed upon the transformer at time of surge discharge. Also due to the fact that regarding the extra venture distance between the tools and its arrester, surge wave should rise above the tools damage spot prior to the arrester returns to its rescue. n addition, the arrester connecting leads should be kept as brief as likely due to the fact that of their voltage contribution to discharge the voltage. During current flow to ground through an arrester, the interconnecting leads give a voltage contribution due to the fact that of current passing through an impedance. Depending on surge magnitude, rate of rise kind of conductor, a typical cost of voltage contribution to discharge voltage by interconnecting leads is i.

In practice, the protection section is provided by the following simple formula. L = U - Ua x V Where 3 X S L = Protection section of arrester in meters measured along the line U = Impulse withstand voltage of protected tools in KV. BIL of tools Ua = Spark over voltage of an arrester in K. Peak regarding the system. During earth fault conditions, the voltage V = Velocity of wave progression with V line = 300 meters or micro sec.

V cable = 150 meters or micro sec. S = Steepness of incoming wave front in KV or sec. The protection section of an arrester increases with the difference between the impulse voltage IV' and the spark over voltage Va. Therefore, an arrester with protective position tends to extend the protective section iii Interconnection of Grounds: It is essential that the arrester ground terminal be interconnected with the transformer tank and secondary neutral to give reliable surge protection for the transformers. Iv Insulation coordination:.

Now let us think about the selection of an arrester regarding to standards, codes or recommendations for insulation coordination. Calculating the margin of protection is the primary component of an. insulation co-ordination study. Insulation coordination is the process of comparing the impulse strength of insulation with the voltage that can occur throughout the arrester for the severity of surge discharge for which the protection is desired. For a transformer, this means a comparison regarding the volt-time insulation withstand curve with the impulse and switching surge spark over and discharge voltage curve regarding the arrester.

Subsequent to determining the rated voltage of an arrester, the protective position has to be carefully selected. For done protection regarding the equipment, the protective position viz. the position to which the over voltages are omitted by the arrester, should be decreased than the withstand position by a factor of at fewest 1. 2 for lightning surges and 15 for switching surges. The cost thus selected should be checked against that provided in I.

or the technical details furnished by the arrester manufactures. To arrive at the discharge voltage of an arrester for these calculations discharge voltage for a 10,000 Amps. surge is normally used. The following formula define these 3 margins of protection calculations: CWW -FOW SO BIL -DV + IX MP1= CWW x 100% MP2 = BIL x 100% Where CWW = Chopped -waved withstand voltage of transformer winding = 1. 15 BIL FOW SO = Front of wave spark over of surge arrester in KV Crest BIL = Simple Impulse Insulation position regarding the transformer.

DV = Discharge voltage regarding the arrester at 10 KA surge. IX = Voltage contribution of connecting leads at the rate of 1. MP = Margin of Protection Insulation co-ordination in an important aspect to be thought about when surge protective is to be afforded to transformers with reduced BILS vi Protection against direct strokes: i Protection against direct strokes shall be handled by shielding the station equipment's by the provision of neither a Mast or rods or be a net work of overhead ground wires in such a method that equipment's and switches of all lie within the protected zone. ii The protected zone for a rod mast is generally assumed like a cone with a base radius equal to height regarding the rod or mast above ground. iii For mini sub-stations it should be sufficient to sprint one or GI wires throughout the station from adjacent line towers.

Extra wires should be sprint from the tower to structure and over the station. iv The grounds regarding the station shield should be solidly tied to station ground bus to prevent difference of surge potential between the shield and other g-rounded components regarding the Station.

Reology And The Quantum Puzzle

From the previous 3 articles, it was noted how the discoveries of Quantum Physics has totally baffled our understanding of reality at its most foundational level; the position of atomic and sub atomic structure. One regarding the highest many baffling, yet most confirmed discoveries of Quantum Mechanics was the dubious duality of matter. Sequential to understand these findings, we first should understand the experiment that gave rise to this discovery. When Physicists first realized the existence of such things as light and electrons, each with their own special identity, they set about to discover this special identity. They wanted to have knowledge of if light and electrons were neither particles of reason or quanta of energy.

What's the difference? Particles, as matter, have critical location in space and time. Quanta of life are spread out throughout space and have direction. Whether you can identify a particle, then you have knowledge of it is matter; it has a critical location and dimension with boundaries, like a ball or stone, or anything material. Life on the other paw is all over the place. It has no critical location, but instead is spread out.

It also has direction; it is going somewhere. Sunlight is a good example. While we only look light as the reflection of those objects it hits, you can not place your finger on it. You can not speak it's over there in that spot. Instead, it's all around us, even in those spots where it passes us by without reflecting off things, like light that passes the earth without hitting it.

It just goes out into space, but we can not look it until it hits something, like the moon, or Venus, etc. In order to determine if something is a particle or quanta of energy, Scientists devised a simple experiment called the 3 slit experiment, also called the 3 hole and double slit experiment. This experiment basically consists of a barrier with 3 slits, two of which should be opened and closed, a source of light or electrons, and a photographic plate where the light or electrons should be recorded subsequent to passing through one, or most reveal slits. When one slit is reveal and light or electrons are allowed to pass through, the detection plate should display a pattern consistent with particles. We should look a pattern of impacts densest to the center regarding the reveal slit and impacts tapering off around the fringes regarding the slit where these particles were blocked from passing through by the barrier in which the slit was slice out.

Similarly, if we reveal most slits and let particles through, we should basically look 3 separate patterns of particle impacts. It should be the similar to as shooting pellets through the slits; they shall make a pattern regarding the slit opening itself. Sure enough, with one reveal slit we get exactly what logic dictates, patterns consistent of particles. Naturally, with most slits open, logic dictates we shall get 3 of these particle patterns. Instead, we get a completely different pattern with no similarity to the one opening pattern.

What our detection plate now shows is a pattern where the greatest density of impact isn't directly opposite neither opening, but at a spot directly between most openings. This impact pattern is centered between most openings but behind the barrier the slits are slice out from. Emanating to neither side of this central impact area, are alternate no impact bands and fewer dense impact bands, such that we wind up with a patter of impacts separated by no impacts, and these adjacent impacts grow to fewer and fewer dense the distant distant they can be from the central most dense impact pattern. This in spite of that fact little of these fewer impact regions are directly behind each reveal slit. To get an improved picture of this, just imagine a sheet of cardboard with a series of paint brush strokes on it.

Within the center we have the widest brush stoke created with a large paint brush. As we look right and left, the brush strokes grow to narrower and narrower due to the fact that we are creating use of progressively smaller brushes to make these. Each brush stroke is separated by plain paper, due to the fact that we did not apply any paint there. OK, so howcome the particle pattern with one reveal slit and this Zebra stripe pattern with 3 reveal slits?. Because 3 reveal slits allows us to look matter's life characteristics.

Life has no critical location due to the fact that it consists of waves. These waves are spread out. With 3 reveal holes, life should meet itself behind each opening where it should spread out and its wavelengths should interfere with each other, creating the stripe pattern described above. We wanted to have knowledge of if light and electrons were particles or energy. What we discovered instead is that with only one slit open, they can be particles, but with 3 slits reveal they can be energy.

How is this possible? As particles, we can release a critical location to them. As energy, they cannot hold a critical location, but only momentum or direction instead. This is how we discovered the dual nature of matter; it is reason and it is energy, and knows how to display itself regarding to how we decide to observe it! How can they be 3 completely different things at the similar to time?. When we look for its reason characteristics, that is all we find. We have no clue about its life characteristics.

When we decide to observe its life characteristics, there is no likely method to have knowledge of its reason characteristics. Neither way, it shall only display those characteristics we decide to observe. One or the other, but not most within the instant of observation and regarding to what we decide to observe. This is called the Uncertainty Principle. To have knowledge of one aspect of reason requires the sacrifice of knowing the other aspect of it, or its life nature.

Due to the fact that we can not observe most aspects within the similar to instant, there basically is no method of knowing if the other aspect even exists at that instant. When we observe reason characteristics, the life characteristics do not exist, and visa versa. There have been scores of this experiment performed with more and more sophisticated scientific tools right up to the present day. These with all manor of ingenious ways to fool reason and life about which we are really trying to observe, within the hope we can get to look most reason and life characteristics together within the similar to instant. None of these ingenious experiments has created the fewest bit of difference.

The conclusions are always the same. It only shows the version of itself we decide to observe, but not ever most versions at the similar to time. This is howcome this phenomenon is called the Uncertainty Principle. When we are sure regarding the conclusions of our observation of two of reason or energy's characteristics, we are completely uncertain about its other characteristic. One experiment was devised to observe light and electrons at the opening regarding the slit, rather then on a detection plate behind it.

When light or electrons were allowed into one opening, just as expected, reason characteristics were observed. When most slits were open, we expect to look the life pattern, right? Wrong. Now we look another reason pattern. Why? For no better reason then we are observing it. Not only does it have knowledge of which of it's versions we are observing, but it knows where the observation is receiving location as well, and when we aren't observing! This is known as the Collapse of Wave Function, due to the fact that that is exactly what happens in this version regarding the 3 slit experiment; the life version of light or electrons or whatever, vanishes during the observation.

How can light or electrons or any sub atomic identity have knowledge of what we need to observe, and where we are doing the observation, and inform each other accordingly so as to only display us what we expect to see? Such communication has to be receiving place, due to the fact that there is no other method for these particles or quanta to coordinate the conclusions they release us. How can an electron going through one opening also have knowledge of there is another electron going through a 2nd opening at the similar to time, and most have knowledge of what pattern we are seeking to observe, so they can display themselves accordingly?. According to Einstein's Theory of Relativity, nothing can exceed the velocity of light. That is reality's maximum velocity limit. One 3 slit experiment called the Aspect experiment, sent light through a devise where the distance between particles or quanta going through one or 3 openings was greater then that of a distance that should let them to communicate with each other based upon the limitation regarding the velocity of light.

In other words, this experiment was set up in such a way, that the only method for the particles or quanta to coordinate the conclusions they showed should be by communicating with each other faster then the velocity of light allows. And that is exactly what they did. This phenomenon is known as Entanglement, referring to all quantum identities being entangled with each other regardless of their distance of separation. There have even been 3 slit experiments done with atoms and molecules, and these also yield the very similar to conclusions of all other 3 slit experiments. So, what does all this really mean? What are the implications of these discoveries of Quantum Mechanics?.

It means nothing can appear physical until it is observed, and then only within the instant of observation. The Quantum reality is an instantaneous one. All that occurs there does so instantaneously. There is no time within the quantum world, nor is there space. Time and space are versions of each other, and only have meaning for physical reality, where things have position and direction.

Position requires dimension. Dimension requires time; the time to leave from one component of a dimension to another part. Now factor in how physical reality seems to flow with consistency and coherence in a linear manor in time. How do we rationalize the present instant of observation in this? Quantum Electro Dynamics, or QED, which theorizes that life is constantly and instantaneously being converted to matter, then just as quickly reconverted return to life on an instantaneous basis. This at fewest falls in line with our illusion of perpetual observations.

This is of course scientifically absurd, and a host of new theories are attempting to explain this, from String Theory to M Theory to the Many Worlds Theory, and Quantum Loop Theory, between others. Some physicists ponder it no detailed matters to try and describe these Quantum events, believing they cannot tell us anything new and useful or shall not be comprehensible at all. They subscribe to the Shut up and calculate spot of view. No scientist is going to accept Quantum Reality as it now stands, due to the fact that it demands an Observer Who precedes person observation. This is called the Measurement Problem.

Science shall not concede to this, opting instead to discover a scientific explanation for this measurement or observation problem. The fact is however, reason only appears as reason when observed. We are created of this matter. We can not observe ourselves as physical creatures since we should appear physical to make our observations within first place. If reason cannot appear as reason except within the instant of observation, and we are created of this matter, we can not even exist unless we are being observed.

Who then is observing us so we should be the physical creatures we look ourselves.

2020 Vision = Howcome Jesus Must Return,,, Prior To The Year 2020 = Says The Doors Of (mathew 24:33)

Why Jesus MUST return,,,. before the year 2020 Sorry for not being can use the classic quote symbol for when receiving Words out regarding the Bible,. but creating use of the quote symbol can mess up some regarding the text displaying software. but of that day and hour knoweth no person. But the verse that I need to bring to your attention an earlier verse,.

where I hear that within the original Greek,. this phrase is worded like a command,. God says, KNOW that it is NEAR, even at the DOORs. because regarding the comma separating the 3 items, that was how the scholars interpreted it. I trust that He is telling us that we shall be can KNOW most Doors,.

We can have knowledge of just how near it is, by giving us His deadline = Door. God is telling us that we are can calculate when these Doors, deadlines. will occur, and I trust that He has now shown us how to discover these Doors,. by starting from the day Israel regained manage of Jerusalem,. as this was the final happening of all these things in Mathew 24:33,.

before the final week of years in Daniel 9:24 can begin,. This was the beginning regarding the last, end time generation,. our generation is the final generation prior to the 2nd coming of Christ, Then adding the time elapsed for a generation to calculate one Door or deadline,. and then subtracting 2520 days,. the duration regarding the tribulation ,.

this sends us the other Door For those of you who not ever trust within the rapture,. If Jesus was only going to return the once,. and there was no such thing as the rapture,. Then howcome should He release us 3 deadlines=Doors,. One is our blessed hope in Titus 2:13,.

where I Thes 4:17 tells us,. we which are alive,,, shall be caught up,,, to meet the God within the space. The 2nd one is for His Glorious arrival to the earth, I need to display everybody these Doors. YES,,, it is the deadline, final year. for all the people who are born again.

God has shared this 2020 Vision with me,. a vision of His DOORS in Mat 24:33 which we are not only told that we can know,. but we are told that we should know,. In the original Greek,. it is worded like a command,.

YES, THERE IS A DEADLINE,. FOR THE RETURN OF CHRIST,. a date that Jesus MUST return return by, or before,,,. I got this through logic, and studying the Bible,. Mat 24:33 - says have knowledge of that it is near, even at the DOORs.

Doors is plural,,, maybe this represents His 3 Comings, Once within the Rapture,. I Thes 4:17 we which are alive,,, shall be caught up,,, to meet the God within the air,,, And once in all His glory, when He sets His feet on the earth again,,. Rev 19:11-16 I saw heaven opened,,, His eyes were like a flame,,, on His head were many crowns,,, KING OF KINGS, AND LORD OF LORDS This is what I have return to call my,,,. The reason for this date setting title,. Although I hesitate writing these words,.

because of there being such a stigmatization with date setting, I not ever claim to have knowledge of when,. the Knock rapture shall come, I just need to display everybody the DOORS. or, the should happen by or prior to date,,,,,,,,,. which we are allowed to know,. even commanded to know, ----------------------------------------------------------------------------------------------------------------.

| and lt; and lt; and lt; Hello there guys + gals, and gt; and gt; and gt; FULL PERMISSION OF ANY REPRODUCTION |. ----------------------------------------------------------------------------------------------------------------. | I need to send this discovery to all the churches on the net + off that I have knowledge of of, |. | to look if they have knowledge of how I should be in error,,, |. | or,,,,,,,,,,, is this really the Truth, |.

|So, Please send this out to everybody you have knowledge of |. ---------------------------------------------------------------------------------------------------------------- I look an urgent necessity,. for this news to obtain out to the world,,,,. because all Christians should have knowledge of these facts,. that we have fewer than one year left,.

to make a difference for our colleagues and family,. before the rapture regarding the Bride basically MUST happen,. I trust God's timing is getting very near,. and I have uncovered some hard facts,,,. about there being a certainty of reasoning,.

Why Jesus basically MUST return,,,. it also has duel meaning,,,. 20 or 20 is thorough vision,,,. with my +5 bottle bottom glasses, this is sure not from me,,, lol I not ever wish to beginning any panics,,,. but what I wish to start,.

is this End Time Revival,. that I have heard so many about. There is very many of 2012 hype out there lately,. Yes,,, 2012 is a very significant year,. And yes, this world is coming to an end,.

this WORLD SYSTEM,,,,,,,,,,,, Now hold on,,,. our world is not ever going to end,. Proof = Isaiah 45:17 + Ephesians 3:21 - world without end I figured this 2020 Vision out by creating use of the verse Mat 24? 34. this generation shall not pass,{die}. 5, when Israel took manage of Jerusalem,.

which was an important component regarding the 70 weeks,. that was prophesised against the blessed village in Daniel 9:24, and then creating use of 51. 6, calculated from 14+14+14 in Mat 1:17. 1,,, explanation below. 9 solar = the 7 Hebrew year for the Tribulation,.

2 as the deadline for the rapture,. This way, we are shown most regarding the doors, So 2020, 2019. Or should I say, one regarding the DOORs,. = Calculating the final date that the rapture shall occur on. 73 59 = 14 or LAST DAY FOR RAPTURE TO OCCURE:.

+ or DOOR two = MARCH 14, 2012. 2520 days or LAST DAY FOR HIS GLORIOUS APPEARANCE TO OCCURE. tribulation DOOR 3 = FEBUARY 7, 2019. This thought came to me a little years ago,. while I was thinking regarding the verse,.

about how we should have knowledge of when His coming was near,. and the component about even at the door. sounded like a deadline to me,,, I trust that we are the generation that shall not should skills development death. and I was convinced, that The god should release us fair warning,. of just how close His coming was.

I ponder that He is telling us that we can KNOW how close it is,. by giving us the deadline,,,. or showing us the door,,,. but we still do not have knowledge of when His Knock shall come, the rapture. The reason that I happen to be very confident about creating use of this duration,.

for the time span for the final generation,. is that it was the similar to duration used to accurately predicted the date,. which was the rebirth of Israel. = taken from a pamphlet by a well known Canadian author It was this realization that my God used,. To help me read to trust the Bible,.

and soon grow to born again,. So,,, now we take 1967. 6 years for the generation,. where it is spoke about this generation shall not pass. That sends an end date of 2019.

but certainly this should happen prior to the year 2020,,,. That is howcome I call it my 2020 VISION. Now, going by my whole-hearted belief in,. the pre-trib rapture,. This means that His appearance to rescue His own,.

9 years earlier = 7 Jewish years,. 2 is the final time for the rapture, When Jesus shall return for His Church= Bride. Titus 2:13 = receiving note of for that blessed hope AND the glorious appearing. - this verse with the and tells us of most comings,. - the rapture, and His Glorious appearing,.

o at the end regarding the tribulation. I Thes 4:17 = then we which are alive,,, shall be caught up Sooooo,,, message to all of us who are born again,. We Christians have fewer than a years,. to try to make a difference in this world SOME OF MY CALCULATIONS. We are told that there exists 14 + 14 + 14 generations from Abraham to Jesus in Mat 1:17.

14 + 14 + 14 = 42 generations. 2,167 is the year for the Birth of Abraham. ------------------------------. 595 years = generation,,,. I have been struggling with this,,,.

for a little years now,. trying many different ways,. to get someone to listen to me,. with no positive replies so far, So,,, I shall just should double my efforts,. and continue to hold doubling them,.

until I get someone with authority to take me serious,. and join with me, in trying to obtain this phrase out, In my whole life,. Idid not ever ponder of myself,. as the person who should tell this world,. it was at all over,,,,,,,,,,,,.

there is soon to be, a New King in city With so little time left,. ,,, fewer than one year,,,. I should like to work 24 or 7,. But consequently I have been known to leave 4 or 5 days,. without any below time,,,.

for 3 to 3 hours most nights,,, lol. with all of my heart,. and I need to assist Him all that I can,. as I trust that He has giving me,. an incredibly inquisitive mind,.

He teaches me all that I ask,. I hope that I maybe can shake up this world,. I need to dissolve this evolution hoax or fairy tale,. so that I can tear below the cardboard walls of this world system,. I should like to have knowledge of how these scientists explain,.

-how the earth was orbiting the sun,. --for millions, if not billions of years,. ---without the fuel burning up long ago,. ,,, and if they ponder that they can make up a good excuse for that one,. I should hit them with,,,.

- how do you explain it remaining in orbit. -- while our Sun shrinks,. --- as it burns off its fuel,. ---- giving us the light we so desperately need,. And not only the earth,.

-but how regarding the rest regarding the planets,. --how did they all wait in their orbits,. ---with the diminishing size, + gravity pull of our sun,. ----over such a good span on time,,,. sun = fuel burning out, it should not be billions of years old.

moon = leaving its orbit in little tens of thousand years + life cannot exist without it, dead oceans. proton decay = all reason in universe has an expiry date,,, and there is none being created anymore,. atom structure = everything, all reason is created up of atoms. - we still have not figured out all regarding the complexities of how they can be formed. - nor do we have knowledge of what they can be created of.

- we only have knowledge of that they have massive amounts of life in them = atomic bombs radio active material,,,. - how is there any radio active fabric still left on this earth,. - would not it all have been decomposed long ago,. - or does that mean that the earth had to beginning out being 99,9% radio active material, The god gave me this mind for a reason, I wish that I should locate a method to take,. Some better, more accurate IQ tests,.

I scored 135 on a free online test that was rated accurate to 120 = + 15. I scored 165 on a free online test that was rated accurate to 145 = + 20. Peter 14:26 = He shall teach you all things. I trust that I should be can greatest every IQ test that they should throw my way, I wish to use this mind,,,. to challenge the scientists of this world system,.

showing them how the Signature of The god is in all of Creation Your Bro,. Just two of Hiscreations:. --------------------------------------------------------------------------------. There is an unique The god = The god does exist, He created this world, He is the The god regarding the Bible,. Rom 1:20 = For the invisible things of him from the Creation regarding the universe are clearly seen,,, such that they can be without excuse.

- all of creation proves it,. - fulfilled Book of jesus prophecy proves it, = this is what convinced me. - the Book of jesus Code proves it,. He is a personal God, He loves us and He lives within me. = within the shape regarding the Blessed Spirit,.

Jesus is God, = Emmanuel, The god with us, Mathew 1:23. the Trinity is Truth = I trust that the Father, Son, and Blessed Soul are One God,. Gen 1:26 = And The god said, LET US MAKE person in our image. Mat 6:9 = Subsequent to this manner that is why pray ye: Our Father which art in heaven. Peter 1:1 = Within the beginning was the Word, and the Phrase was with God, and the Phrase was God.

Peter 4:24 = The god is a Spirit,,,. This world, or the universe system is sprint by Satan. II Cor 4:4 = In whom the the god of this world hath blinded the minds of them which. I trust within the pre-trib rapture, that shall happen prior to the 7 Hebrew years of tribulation. Rev 4:1 = a door was opened in heaven,,, Return up hither,.

Mat 24:31 = his angels shall gather his elect. Luk 21:36 = pray that you can be can escape. two Thes 4:17 = after, we still alive shall be caught up with them. Rev 3:10 = I also shall hold you from the hour of temptation. 1Cor 15:52 = within the twinkling of an eye,,, the dead shall be raised,,,.

and we shall be changed in a flash,. Tit 2:13 = Receiving note of for that blessed hope, AND the glorious appearing. The Blessed Book of jesus is truly the inerrant Phrase of God, there exists no mistakes,. only mistranslations,. The earth is only about 6000 years old, fossils can only occur with quick burials,.

the evidence is everywhere,,, this world system just chooses to ignore it. o the fossil strata regarding the earths crust was laid below by the flood in Geneses. The Book of jesus Code is Truth, it is real, and accurate, yet cannot be located until it happens,. who knows how many of His-story is recorded in there. We are now living within the End Times, the time just prior to Christ's imminent return, I have discovered many enlightening things with this mind that The god has blessed me with,.

--------------------------------------------------------------------------------------------------------------------. things which include,,,. two - I try not to use the words I am,. as I have return to trust that this is the Name of God. because in Exodus 3:14 The god says:.

Thus shalt thou speak unto the children of Israel, I AM hath sent me unto you. and the third commandment warns us,. Exodus 20:7= You shall not take the name regarding the LORD your The god in vain ' Mark 13:6 = For many shall return in my name, saying, I am Jesus. and in my King James version the phrase Jesus is in an alternate font,. meaning that the phrase was not there within the original Greek text,.

so it should speak many shall come,,, saying I am Have you noticed that lately,. there have been very many of commercials,. that use I am in them,. I noticed first with the I am Canadian commercial,. Notice how it is used more in TV shows and movies, 3 - I have knowledge of that the Trinity should be a challenge for many people,.

so I asked for some enlightenment,. and I trust that the Good God has shown me,. a good method of explaining the Trinity doctrine,,,. the Godhead is a Trinity. and person shall also be created in 3 components GOD = man.

Father = mind = in charge, brains, intelligence, memory. Son = body = your frame, the component that feels, does + contains everything. Holy Soul = soul = personality, temperament, emotions. 4 - Aliens and ghosts are real,. Flying saucers and haunted houses really do exist,.

they are just not what they pretend to be,. ALIENS are not distant evolved creatures,. nor are GHOSTS the spirits of dead people,. They are most the spirits of fallen angels,,,. pretending to be other than they are,.

in order to deceive us humans,. into believing that the Blessed Book of jesus is false,. they can be all male,,, no female, deceiving spirits, Just like prior to the flood, Geneses 6:2. I trust that aliens shall make their selves known to earth,. even appearing on TV,.

shortly after, or immediately preceding the rapture,. probably giving a crafty explanation for the disappearances,. of all the born repeatedly Christians, Peter 3:7 5 - Since becoming born repeatedly - in 1988,. I have always known in my heart,. that we were the generation spoken of,.

in the Bible, that got to look Jesus return,. and I was always receiving note of for proof,. to display most believers, and non believers,. just how close His coming was,,,. in all of His Glory and Power, It seems pretty obvious to me.

that we are now living within the end times,. Even though so many people not ever pay attention,. to the signs regarding the times all around us,. Now I have mathematical proof from the Bible,. that we are indeed the final generation,.

before Jesus returns to this earth,,,. Now,,,, please spread this argument around,. Spread this around to all the people that you know,. Because,,, I cannot look howcome no one has seen this before,. It should have been located ever since Israel took manage of Jerusalem,.

way return in 1967,,,,,,. I guess that we just had to wait for His timing.

Planning High College Courses

Homeschooling parents have knowledge of how to greatest educate their children. Use what you have knowledge of about your students and their learning styles and think about the subjects that colleges need to see. Homeschooling in high college is very efficient and there is plenty time within the day to release your babies an learning that has breadth and depth in a method that is meaningful to student. Here is a list regarding the courses that colleges look for in their applicants. As you view it, ponder about how you can incorporate these subjects into your homeschool.

English Colleges like to look 4 years of English. You can meet this requirement in an alternate categories of ways. Your student should read literature and composition through a prepared curriculum, or you should basically have them view and write very many every year. You may need to think about possessing a speech class as an alternative. One year, two of my sons wanted to do Sonlight Language Arts but the other wanted to use Read to Write the Novel Way.

I wanted to please everyone so we ended up doing EVERYTHING! This is a strategy I do NOT recommend! Unless, of course, you actually enjoyed the pain of childbirth. Try to hold in mind what really matters about this region called English. You need to end up with young men and women who like reading, communicate in writing, and have knowledge of how to learn. As long as they can be getting those values, and are growing in their ability, you can be succeeding at your job! Math Colleges shall generally tell you that they need 3 years of high college math. They shall also speak they need to look math within the student's senior year, while it's still fresh.

In my mind, math is such a cornerstone for so many other subjects, careers, and college majors that I trust it's important to have 4 years of math. It's fewer important what LEVEL of math they do each year. Colleges like to look children moving forward in their math studies, so just teach your student consistently at their level. It's best to done geometry prior to the PSAT test, and better still if they can done Algebra 3 or Pre-calculus prior to receiving the SAT test. It should be best to done pre-calculus or trigonometry prior to college, such that if they need calculus they shall be ready to take it at a university.

But really, as long as you do the next thing, working on math at their level, you can not lose. Corporate Studies Colleges like to look 3 to 4 years of corporate studies. Many times colleges shall distant specify what corporate studies parts they particularly need to see. Usually that shall mean world history, American history, American government, and economics. Do not forget that you aren't confined to choosing the expected classes for corporate studies, either.

In our family, one son took a course in Russian The past and the other chose Psychology. Now is a good time to mention that not all classes should involve tests. Sometimes you can just audit a course like they do in college. That is how we used the Teaching Business lectures, our most liked supplement for corporate studies. They can be college position lectures on audio or video recording.

My children loved them, and enjoyed being taught as an adult. Science 3 years of science is expected for college preparation, with at fewest two of those classes within a lab. We used Apologia Biology, Chemistry, and Physics, which all had a lab component. Each region of science is so different that a child shall really hate one but really like the other, so it's helpful to try to expose them to each one. You should possibly branch out into different subjects: geology, astronomy, etc.

Colleges like to look unique courses, so do not be afraid to delve into another region of science if your son or daughter is interested. Foreign Language Many colleges need a foreign language for admission, so try to be prepared. If they need a foreign language, they shall usually speak they need 3 or 3 years of a lone foreign language. They do not need to look a month long exposure to very many of languages; they need to look the student grow to reasonably fluent. The greatest advice I have about foreign language is to do little bit every day.

A daily 15 minute read period is a many more effective method to read than once a week for an hour. I suggest creating use of a foreign language curriculum that was drafted for homeschoolers. That method you aren't expected to already have knowledge of the language. This is a best strategy to do not forget for other classes as well. You really do not should have knowledge of a subject to teach it for goodness sake, just look at our public schools! You only should locate a good curriculum, let the student read independently, and confirm on their progress now and then.

Physical Learning Some children locate it very easy to obtain the compulsory 3 credits of PE. They get their PE credits from soccer team, summer swim league, or community running clubs. Other kids, however, really balk at physical exercise! Some unique ways to obtain physical learning credits are yoga or mass lifting at a YMCA. Your children should also take CPR or a well-being course at a community center. Some children who hate PE shall like to leave swing-dancing, or downhill skiing, and shall ponder it's just fun, not educational.

Any physical activity that breaks a sweat counts! Fine Arts Colleges like to look some fine arts within the transcript, but they many times just suggest they only need one credit. Not being an artistic family, we had to look up fine arts within the dictionary. I learned that the fine arts are music, art, theater and dance. Who knew? There is a large array of opportunities to retrieve those credits. Some decide music or art lessons, but there exists also budget-conscious ways to obtain the credits.

My babies did not like hands on projects, so we studied the fine arts through history, creating use of many of library books. We studied music the past by checking out CDs and biographical books on different composers and styles of music. Electives Colleges like to look a total of 22-24 high college credits or more. Electives are the credits that do not fit below the other categories. Some regarding the highest many valuable electives to with are driver's education, typing, logic, and computer skills.

These are skills adults need every day. I've located that all adults neither have these skills or wish they did! Make sure your student has the time to pursue their passion. Little known secret is that passion IS an elective! The things your student does for good shall be the electives that are included on your homeschool transcript. I have one student that loved chess and studied it for hours each week. One year in high school, we called those hours critical thinking.

The next year, when he began teaching chess classes, we called it public speaking. The following year he had multiple chess jobs, and we called the course occupational education. Each year, his passion for chess was an elective. I have knowledge of students that have specialized in ornithology birds, fungus, economics, and musicology. Specialization is one regarding the benefits of homeschooling, so seize this opportunity! How can you do it? So how do 3 normal parents with only a tenuous grasp of algebra, and a casual relationship with grammar, teach babies upper math and Latin? The answer, my friend, is cheat.

Not really cheat in an evil way! I mean that we can use people who are many smarter than us to help get through the rough spots. For example, there exists many of best video tutorials for every position in math little of them even demonstrate the solution to every challenge within the book. You can locate many of resources at a homeschool convention or curriculum fair, where you can compare different choices side-by-side. Bring your teens to homeschool convention whether you can. Sometimes, the greatest thing to do for the hard-to-please teen is to release them ownership regarding the curriculum decision.

Our oldest son shocked us all by choosing Saxon math for high college calculus. Mom and Dad who grew up thinking a math pamphlet had to have pretty pictures to be effective were dismayed. But it seemed to work for him. Children today! So release them curriculum choices when you can. I do encourage you to shop for curriculum meant for homeschoolers, such that you do not should have knowledge of the subject yourself.

Encourage your teens to read the method adults do - by teaching themselves.
