Amps (A) to kilovolt-amps (kVA)Enter phase number, the current in amps, the voltage in volts and press the Calculate button to get the apparent power in kilovolt-amps:
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
