Single phase amps to kVA calculation formula

The apparent power S in kilovolt-amps is equal to current I in amps, times the voltage V in volts, divided by 1000:

S(kVA) = I(A) × V(V) / 1000

3 phase amps to kVA calculation formula

Calculation with line to line voltage

The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line to line RMS voltage VL-L in volts, divided by 1000:

S(kVA) = 3 × I(A) × VL-L(V) / 1000

Calculation with line to neutral voltage

The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line to neutral RMS voltage VL-N in volts, divided by 1000:

S(kVA) = 3 × I(A) × VL-N(V) / 1000
