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
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
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
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).
