This calculator is useful to you to find out kilo volt-ampere of any equipment. You can find kVA of single phase and three phase equipments.
How to use the calculator?
- From the drop down, select the phase.
- For this calculator, note down the voltage, rated current. 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 calculate kilo volts-ampere of equipments?
For single phase, kilo volt-ampere (kVA) is equal to rated voltage (V) multiply by current. Divide that result by thousand to get the final result in kilo volt-ampere.
Example: Let us say you have 230 VAC equipment and current is 100 amps. The calculated kilo volt-ampere is 23 kVA.
For three phase, kilo volt-ampere (kVA) is equal to square-root of three multiply by rated voltage (V) multiply by rated current (I) whole divided by thousand.
Example: Let us say you have transformer at LV side voltage is 415 VAC and rated current 2000. For this transformer, the calculated kVA is 1435.9 kVA.
