In Watt's Law, power (P) equals the output voltage (E) times the ampere capacity (I). Using this formula, P = E x I, and its direct derivatives, I = P / E and E = P / I, all transformer attributes can be calculated. For example, if the transformer's rating is 10 KVA and has a 240-volt output, it has a current capacity of 41.67 amperes (10,000 ...
I discussed a step up transformer that was 225 kva, 208v primary (line to line), 480v secondary (line to line), 277v (line to Neutral) with POCO and he stated even using that transformer my current 208 high-leg service would not work.

It also provides a secondary voltage of 240V and has 93.75 amps available on the secondary side.You may require a 240 to 480 step-up transformer because you are working with equipment needing 480 volts in three-phase power. Most household appliances operate on 120 volts. This kind of transformer is a step-up transformer. The power across transformers remains at a constant value.Jul 31, 2018 · So this transformer is what we would normally think of as a 208V to 480V step _up_ transformer even though power is flowing from the 480V side to the 208V side. Remember that transformers are bidirectional; what differentiates the primary from the secondary is leakage inductance to limit inrush current when you energize the thing and which coil ... If the motor wants a full 230 volts, use two autotransformers in open delta. The cost of the two auto-transformers and a larger contactor is usually much less than the cost of a 208:480 volt transformer. (460 volt motors are commonly used on 480 volt systems. 208:480 is a more common transformer voltage than 208:460.as voltages of “240 x 480” or “120/240.” If the series-multiple winding is designated by an “x,” the winding can be connected ... transformers with a sound reduction up to 5 dB below NEMA ST-20 limits.
