by

Amps (A) to kilovolt-amps (kVA) calculator.

Enter phase number, the current in amps, the voltage in volts and press the Calculate button to get the apparent power in kilovolt-amps:

Select phase #:  
Enter amps: A
Enter volts: V
   
Result in kilovolt-amps: kVA

Single phase amps to kVA calculation formula

The apparent power S in kilovolt-amps is equal to current I in amps, times the voltage V in volts, divided by 1000:

S(kVA) = I(A)× V(V)/ 1000

3 phase amps to kVA calculation formula

Calculation with line to line voltage

The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line to line RMS voltage VL-L in volts, divided by 1000:

S(kVA) = √3 × I(A)× VL-L(V)/ 1000 

Calculation with line to neutral voltage

The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line to neutral RMS voltage VL-N in volts, divided by 1000:

S(kVA) = 3 × I(A)× VL-N(V)/ 1000
