kVA Calculator
English

kVA is kilo-volt-ampere. It is an unit of apparent power used in obtaining the electrical capacity of circuit breakers and wirings. One kilo-volt-ampere is exactly equal to 1000 volt-ampere. Here volt is an electrical pressure and amp is an electrical current. Use our online Single, Three Phase kVA Calculator to find the KVA value. To calculate Kilovolt-amps (kVA), select single phase or three phase connection from the drop down, and convert the KVA calculation for Volts (V) and Amps (A).

Formulas Used:

Three phase = I x V x 1.732 / 1000 One / single phase = I x V / 1000
Where, I = Amps V = Volts

Example:

Calculate kVA value for three phase voltage of 5 v and 8 amps.

Solution:

Kilo-volt-ampere = (8 x 5 x 1.732) / 1000
= 0.06928 kVA.
