Amps (A) to volt-amps (VA) calculator and how to calculate or how to use it.
Enter phase number, the current in amps, the voltage in voltsand press the Calculate button,
to get the apparent power in volt-amps:
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)
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)
