Single phase amps to VA calculation formula

The apparent power S in volt-amps is equal to current I in amps, times the voltage V in volts:

S(VA) = I(A) × V(V)

 

3 phase amps to VA calculation formula

The apparent power S in kilovolt-amps is equal to square root if 3 current I in amps, times the line to line voltage VL-L in volts:

S(VA) = 3 × I(A) × VL-L(V)  = 3 × I(A) × VL-N(V)
