kVA to Amps calculator

Enter the apparent power in kilovolt-amps (kVA), voltage in volts (V), then press the Calculate button to get the result in amps (A).

Single phase kVA to Amps calculation

Apparent power in kVA
Voltage in volts (V)

I(A) = 1000 × S(kVA) / V(V)

The current I in amps (A) is equal to 1000, multiplied by the apparent power S in kilovolt-amps (kVA), divided by the voltage V in volts (V).

Three phase kVA to Amps calculation

Line to line voltage

Apparent power in kVA
Voltage in volts (V)

I(A) = 1000 × S(kVA) / (√3 × VL-L(V))

The phase current I in amps (with balanced loads) is equal to 1000, multiplied by the apparent power S in kilovolt-amps (kVA), divided by the square root of 3, multiplied by the line to line RMS voltage VL-L in volts (V).

Line to neutral voltage

Apparent power in kVA
Voltage in volts (V)

I(A) = 1000 × S(kVA) / (3 × VL-N(V))

The phase current I in amps (with balanced loads) is equal to 1000, multiplied by the apparent power S in kilovolt-amps (kVA), divided by 3, multiplied by the line to neutral RMS voltage VL-N in volts (V).
