3-Phase kVA Calculator | Easy & Accurate

Determining apparent power in a three-phase electrical system involves multiplying the voltage and current, then factoring in the square root of three (approximately 1.732) for balanced loads. For instance, a system with 480 volts and a current of 20 amps per phase would have an apparent power of (480 20 1.732) / 1000, resulting in 16.6 kVA.
