amps X volts / 1000 = Kva (for a single-phase system).Kva stands for Kilo-volt-amperes, and the Kilo- prefix means thousands.Also, Kva X Power Factor = KwExample:120 volt, single-phase load drawing...
First determine what voltage is needed for phase to phase. Where you work on or where the gears are coming from would help to answer this question. In Southeast Asia, where power is 220~240 volts, a...
