## kVA to Amp Calculator

How to use the calculator?

• From the drop down, select the phase.
• For this calculator, note down the voltage and kVA of the equipment. You can find details from the equipment’s nameplate.
• Enter the data collected in respective fields.
• The calculator would show automatically the calculated value.

## How to convert kVA to Amps?

### Single Phase formula to convert kVA to Ampere

For single phase, amperes (I) is equal to kilo volt-amperes (kVA) multiply by 1000 whole divided by Voltage (V). Multiplying by thousand would convert kilo volt-amperes into volt-amperes. Example: Let us say you have 50 kVA transformer with LV side rated voltage is 230 VAC  input current of transformer is 43.478 amps.

### Three Phase formula to convert kVA to Ampere

For three phase, amperes (I) is equal to kilo volt-amperes (kVA) multiply by 1000 whole divided by Voltage (V) multiply by square root of 3. Example: Let us say we have 5000 kVA transformer with LV side rated voltage is 6.6 kV then the rated current of transformer at LV side is 757.576 amps.
