In order to calculate three-phase wattage, the voltage of each phase is multiplied by the current of each phase, which is then multiplied by the power factor, and this value is multiplied by the square root of three (the square root of 3 is equal to 1.732). To measure the three-phase power consumed by a loaded motor, a power analyzer is connected.
