Q: Single bus sub-section for power distribution, transformer with a prepared and dual-use how to understand
One with a prepared, you can only put one of the transformer, any of its transformers can all the load to bring all the general into the line breaker and bus in the breakdown of the circuit breaker, interlock between the three, A change vote, B variable can not vote, or vice versa, B cast A can not vote. This is the nature of the load mostly for a load, power supply is necessary for high reliability, but also the largest investment. Dual use can be divided into several, mainly refers to the change can be put into use, and some can be put into the parallel use, in some cases is not allowed to use in parallel, is the three circuit breakers with interlocking Three locks two spoons, three circuit breakers can only vote two. At the same time the capacity of the transformer is also different, some are prepared, some are dark spare, the specific use depends on how the original system design. hope this helps.
Q: For most consumer electronics, there'll be a transformer within the adaptor that converts AC to DC. For the basic of the transformer, I'll just assume it's just a primary coil running the secondary coil.So, the primary coil keeps on running at full power, as long as electricity is needed for the appliances. Does this mean that even on standby mode, the adaptor still takes in full power from the power socket?
the adapter contains a Transformer to drop the voltage and a rectification circuit to convert from AC to DC to smooth the rectified voltage. the transformer has only a small amount of power consumption when the secondary coil has no load, Although the winding resistance of the primary coil is a constant the current flow through it is restricted by the magnetic field. the rectification/smoothing circuit is likely to cause some load even if there is nothing connected to the outlet of the transformer.
Q: I am powering a lighting system with a mixture of SCR dimmers and HID lamps. I am pulling approx 285 amps/leg at 120/208V through a 150 kVA transformer. The 120/208V service coming from that transformer is indicated to be 400A/leg, but it seems to get pretty hot at 285A.
Three phase transformers are given a power rating which is the sum of all three powers on each phase. So 285 amps on each phase at 120 line to neutral (assuming this is how youve them connected) is about 35kva, so about 100kva all up. What is actually on the name plate of the transformer? How hot is 'pretty hot'? Is it running as it was desinged (oil, dry, forced air cooling etc). Also how are your lamps/dimmers wired? The other answer is correct, the dimmers will produce alot of harmonics. The meter your are using to read the current is most likely designed to read a 60hz sine wave, any other stuff there will cause a wrong reading (they usually measure the average value, then apply a correction factor to obtain the rms value. But this factor depends on the wave shape, if its not a sine wave it will be wrong). See if you can obtain a meter that will measure the true RMS current. Transformers of that size are usually heavily over engineered, it should be fine as long as the tempertature doesnt continue to increase, ie to the point where the case is too hot to touch. As the other answer said it is probably rated for continuous operation at about 75 degrees. Id not worry too much as long as the temperature doesnt continue increasing.
Q: coz in a step up transformer the voltage is increased and the and the current is decreased and vice-versa . and the ohm's law states that voltage is directly propotional to the current .now in a transformer we r making the current inversly propotional to the voltage
A transformer does not make the current inversely proportional to the voltage; the currents in the two coils are inversely proportional to the turns ratio Q. If the secondary (output) coil drives a resistance, the current depends on Ohm's law; Is Vs/R. The resistance equals the ratio Vs/Is. But the ratio V/I in the primary (Vp/Ip) is multiplied by Q^2; that is, V is proportional to Q and I is proportional to 1/Q. So the power source driving the primary sees a load resistance Q^2R. The power, or product of V*I, is the same in the primary and secondary. But no matter what you do with the input voltage, the currents in both windings change proportionally to voltage. You can think of a transformer as similar to a lever, where V and I correspond to F and d (distance), F/d correwponds to R, and Q corresponds to the applied-work and output-work lever lengths. Work Fd is constant on both ends of the lever, and F/d has a Q^2 relationship between the two lengths of the lever.
Q: i just bought transformers Infiltration and Stormbringer graphic novels of idwi know that they are continuing and continue like this1.Infiltration.2.Stormbringer.3.Escalation.4.Devastation.5.Revelation.i wanna know what graphic novels come after these and what is the name of all of these mini series together?
Megatron Origin is the first story, then Infiltration, Stormbringer, Transformers/New Avengers, Escalation, Devastation, followed by Maximum Dinobots. The Spotlight (Revelation) stories interweave into the main plot as well (4 volumes all together). All Hail Megatron is next, with more Spotlight stories collected in All Hail Megatron vol. 3 4. Then Last Stand of the Wreckers, Transformers Bumblebee, Transformers Ironhide, and Transformers Drift. The ongoing monthly title follows, as of this typing only two paperbacks collecting it are out.

Q: How do step up transformers obey the law of conservation of energy?
An ideal transformer neither generates nor consumes energy, so the power entering it will equal the power leaving it. Power can be computed by multiplying the RMS voltage by the RMS current. So, if an ideal transformer has an input voltage of (say) 100 V and an output voltage of 200 V, the current coming out will be exactly half the current going in. A real transformer is not ideal but dissipates power owing to the finite resistance of its windings and other effects, so if a real transformer steps up voltage from 100 V to 200 V, its output current will be less than half its input current.
Q: An AC adapter for a telephone answering machine uses a transformer to reduce the line voltage of 120 V to a voltage of 8.00 V. The RMS current delivered to the answering machine is 570 mA. If the primary (input) coil of the transformer has 600 turns, then how many turns are there on the secondary (output) coil?What is the power drawn from the electric outlet, if the transformer is assumed to be ideal?What is the power drawn by the transformer, if 13.5 percent of the input power is dissipated as heat in the coils and in the iron core of the transformer?
Hello Samantha, in case of ideal transformer the power at the out put would be the same as that in the input. To get the power we need voltage and current. Voltage at the out put is 8 V and current is 570 mA. Hence power consumed by the machine is 4.560 W. So the power drawn in case of ideal transformer will be the same as 4.560 W If the efficiency of the transformer is 86.5% (100-13.5) then the input power will be 5.27 W (approx) To get the number of turns in the secondary let us use Ns/Np Vs/Vp Hence Ns 600*8/120 40 turns.
Q: What does S11-M-500/10 transformer mean?
S represents three phases 11 design number M indicates sealing 500 indicates that the transformer capacity is 500KVA 10 indicates that the rated voltage of the transformer high voltage side is 10KV
Q: I would like to attend a Transformers 2 Premiere where the cast will be present. Is that possible? Are these shows usually closed/private? Do I have to be in Hollywood? What should I do?
I think so.
Q: Hi - I have some questions for any electrically minded people out there!I have a low-voltage 12v transformer, as pictured here:
That 'transformer` creates a 'separately derived system`. There should be no potential to ground. You can 'safe` the wires in the attic temporarily with 'wire-nuts`. (Conical plastic splice fittings.) If you're having trouble with the transformer look for: * Is the unit overloaded. (Any shorts/grounds in the L.V. wire.) * Is the unit adequately cooled. (There must be air flow at those vents.) * Is the 'high pot.` side connected properly?
