Single Phase kVA to amps calculation formula The current I in amps is equal to 1000 times the apparent power S in kilovolt-amps divided by the voltage V in volts: I_{(A)} = 1000 * S_{(kVA)} * V_{(V)} |
Three phase kVA to amps calculation formula Calculate with line to line voltage The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovolt-amps divided by the square root of 3 times the line to line RMS voltage V_{L-L} in volts: I_{(A)} = 1000 * S_{(kVA)} / (√3 * V_{L-L(V)}) |
Calculate with line to neutral voltage The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovolt-amps divided by 3 times the line to neutral RMS voltage V_{L-N} in volts: I_{(A)} = 1000 * S_{(kVA)} / (3 * V_{L-N(V)}) |
