How to calculate the kVA of an electrical device?
Single Phase formula to calculate kVA
For single-phase, kilo volt-ampere (kVA) is equal to the rated voltage (V) multiplied by current. Divide that result by a thousand to get the final result in kilo volt-ampere.
Three Phase formula to calculate kVA
For three-phase, kilo volt-ampere (kVA) is equal to the square root of three multiplied by rated voltage (V) by rated current (I) whole divided by thousand.
