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.: From your readings ,the transformer is within it's rating. Power Transformers are usually rated to operate at 75 Deg. C and above. Sometimes up to 95 Deg. C. The data and limit will be on the nameplate. 75 Deg. C is uncomfortably hot. 95 Deg. C. will burn you. Note; SCR dimmers WILL produce harmonic currents that will increase the 'neutral load' well above 'phase load' on 'common neutral' circuits, and might be producing some high frequency heating in that T/F.

Q: I work in the power plant, today there is a task is to charge the lighting transformer, I would like to ask the next. What does it mean to charge the transformer? What does this charge mean? What is the use of? Thank you: To the transformer charge, that is, to the transformer side of the side with the rated voltage, the second disconnect, run a certain time and then close the second switch, and gradually bring the load.

Q: If load loss of a transformer at full load is 100kW, the load loss at 50% load will be a) 50kW b) 75kW c) 25kW d) 100kW. i think its 25kW because load loss is inversely proportional to the square of loading percent. kindly explain . is it right.: I'm guessing load loss is the same as copper loss, which is due to the resistance of the wire in the transformer. This loss is (I^2)(R wire) so the answer is c) 25 KW The current is 50% at 50% load, I^2 0.25

Q: Can transformer be used to change direct current e.m.f? If not , why?: A transformer works from the expanding and collasp of a magnetic or inductive field. Without the expandin or contracting field, no lines of flux are cut. What is possible instead is to use a chopper circuit and convert the DC to AC run it through a transformer and then rectify the AC back to a pulsating DC and then filter it back to pure DC.

Q: What is the reason why the dry transformer is loud: 500kva below the dry-type transformer noise 56 to 58 dB or so, 630kva above 62 to 65 dB or so! This is our factory data. The dry-type transformer sound is great. Big like cattle called the same, because the core is loose!

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: can u use a 220v to 12v transformer step down transf, switch the primary as the secondary, and vice and make it a 12v to 220v transformer.: confident. you will incur larger losses than if the transformer became particularly designed for 220 V, inspite of the undeniable fact that it is going to in all possibility be insignificant. be conscious, inspite of the undeniable fact that, that attempting the different (making use of a transformer designed for 220 V in a 440 V circuit) might _not_ paintings, because of the fact the conventional might overheat.

Q: I have a transformer of 12060 Volts and a transformer of 15000 Volts, both neon-sign types; if I wired them together, would it amplify the output voltage or have a catastrophic effect that would end the world as we know it?But really, can I wire them together for an added effect of some kind?Thanks.: Yes the PS and PS 2 are likely problems. The switching type are likely rare for this high a voltage. Use the transformer with the broadest surface as the base and mount the other at least two inches 5 centimeters above it with very high voltage electrical insulators. This MAY reduce the problems with leakage to the case and excessive stress on the internal insulation. Connect the primaries in parallel; the secondaries in series and you MAY get 27000 volts, perhaps MORE. Be prepared to cut the power quickly if either transformer makes arcing sounds or smokes. Be careful, these transformers often give DEADLY shocks. My advice is sell them cheap on E BAY before they put you in an early grave. Neil

Q: how transformer came to know that it has to draw lagging current during summers: The transformer itself is inductive, as others have said, so it will always appear as a lagging load. Now, in the summer, most people are using their air conditioning systems, which are quite inductive because they're essentially just motors. So, the load attached to the transformer could be a good bit more inductive than in other seasons.
