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 VL-L in volts: I(A) = 1000 * S(kVA) / (√3 * VL-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 VL-N in volts: I(A) = 1000 * S(kVA) / (3 * VL-N(V)) |
