Amps to kVA Calculation

Single phase amps to kVA calculation formula

S(kVA) => I(A) × V(V) / 1000
The apparent S (power) in kilovolt-amps is equal to I (current) in amps, times the V (voltage) in volts, divided by 1000.

3 phase amps to kVA calculation formula

Calculation with line to line voltage

S(kVA) => √3 × I(A) × VL-L(V) / 1000
The apparent S (power) in kilovolt-amps is equal to phase I (current) in amps, times the line to line RMS voltage VL-L in volts, divided by 1000.

Calculation with line to neutral voltage

S(kVA) => 3 × I(A) × VL-N(V) / 1000
The apparent S (power) in kilovolt-amps is equal to phase I (current) in amps, times the line to neutral RMS voltage VL-N in volts, divided by 1000.

Amps

Amps measure the flow of electricity as an electric current. Specifically, it measures the amount of electrons that flow past a certain point per second.

Kilovolt-amp (kVA)

The unit KVA (kilovolt amperes) is a measure of the power in an electrical circuit.
1 kilo-volt-ampere is equal to 1000 volt-ampere.
