How to Convert kVA to Amps

kVA, short for kilovolt-amps, is a measure of the apparent power in an electrical circuit. 1 kVA is equal to 1,000 volt-amps and are most commonly used for measuring apparent power in generators and transformers.

Amps are a measure of electrical current in a circuit.

In order to convert from kVA to amps we’ll also need the voltage of the circuit, and then we can use the formula for power

The formula to convert kVA to amps is:
Current(A) = (1,000 × Power(kVA)) ÷ Voltage(V)

This means that amps are equal to the kVA times 1,000, divided by the voltage.

For example, let’s find the current for a 220 volt circuit with 25 kVA of apparent power.

Current(A) = (1,000 × 25 kVA) ÷ 220 V
Current(A) = 113.64 A

How to Convert kVA to Amps in Three-Phase Circuits

The formula to convert kVA to amps in a three-phase circuit looks like this:
Current(A) = (1,000 × Power(kVA)) ÷ (√3 × Voltage(V))

So, amps are equal to 1,000 times the power in kVA divided by the square root of 3 (1.732) times the voltage.

For example, let’s find the current for a 440 volt three-phase circuit with 50 kVA of apparent power.

Current(A) = (1,000 × 50 kVA) ÷ (1.732 × 440 V)
Current(A) = 65.608 A
