Amps to kVA calculator Single phase kVA to amps calculation formula. 8 kilovolt-amps (approximately 5 kVA) Three-Phase Sizing. 3 Phase Generator - kVA / kW / Amp Conversion Chart Chart shows the estimated output amps of a generator based on operating power and voltage with 0. In a balanced 3 phase system KVA would be three times the power in one phase. For an example let's use Load voltage = 480 volts, Load current, = 80 Amps and Line voltage = 208 volts. Ampere is the SI unit of electric current represented as 'A'. With a 1000 kVA, 480 VAC secondary, 1203 amp, 5. The equipment documentation shows a requirement for a 50-amp 208-240 VAC power source.
