3 phase amps to VA calculation formula The apparent powerSin volt-amps (VA) is equal to square root of 3 times currentIin amps (A), times the line to line RMS voltageVL-Lin volts (V): S(VA)=√3×I(A)×VL-L(V) So volt-amps are equal to square root of 3 times amps times ...
The line to line RMS voltageVL-Lin volts is equal to the powerPin kilowatts, divided by square root of 3 times thepower factorPFtimes the phase current I in amps: VL-L(V)= 1000 ×P(kW)/ (√3×PF×I(A)) So volts are equal to kilowatts divided by square root of 3 times power...
