have you seen a point where voltage and amps are NOT inversely proportional ? i have a .75 hp 120/240 volt single phase split capacitor motor running at 16.7 no load amps @ 128 volts. When we run it at 120 volt, it runs back within its' rated amperage.

it is an open transistion... we have looked at an updated micrologic type breaker. this would allow for some "tweeking" of set points. rightnow it is a simple thermal / mag. breaker. the consederation of possible ferroressonence is my main consern on a delta wye config.
any thoughts on...
rbulsara this is a new problem since we installed the step up transformer. we did use a volt meter with factory tech. and it monitors all three phases.. we have an allen bradley power monitor on line and it records a max current each time from 1.4ka to 1.6ka...
I am having some issues with a 208Y 4w / 4160D system. we are stepping up from 1200 amp 208 to a 300 kva 120/208 Y to 4160D transformer to another building and stepping back down to 120/208 3ph 4w system. the problem when we transfer from generator power to normal with inphase monitor on the...
