How to Calculate Amps (A) to kilovolt-amps (kVA)

Single phase amps to kVA Formula
S (kVA) = I (A) × V (V) / 1000

Power S in kilovolt-amps equal to current I in amps, multiply the voltage V in volts, divided by 1000.

Three phase amps to kVA Formula
Line to line voltage

S (kVA) = √3 × I (A) × VL-L (V) / 1000

Power S in kilovolt-amps equal to phase current I in amps, multiply the line to line RMS voltage VL-L in volts, divided by 1000.

Line to neutral voltage

S (kVA) = 3 × I (A) × VL-N (V) / 1000

Power S in kilovolt-amps equal to phase current I in amps, multiply the line to neutral RMS voltage VL-N in volts, divided by 1000.
