Single Phase kVA to Amps Calculation Formula

I(A) = 1000 × S(kVA)V(V)

S(kVA) – Apparent power in kVA.

V(V) – Voltage in volts.

For example, let’s find the current for a 230-volt circuit with 20 kVA of apparent power.

I(A) = 20 kVA × 1,000/230 V = 86.9565 A

3 Phase kVA to Amps Calculation Formula

Calculation with Line-to-Line Voltage

I(A) = 1000 × S(kVA)√3 × VL-L(V)

VL-L(V) – Line-to-Line voltage in volts;

S(kVA) – Apparent power in kVA.

For example, let’s find the current for a 400-volt three-phase circuit with 25 kVA of apparent power.

I(A) = 25 kVA × 1,000/1.732 × 400 V = 36.0854 A

Calculation with Line to Neutral Voltage

I(A) = 1000 × S(kVA)3 × VL-N(V)
