      B3.2.3 Power Calculations in Balanced Three-Phase Circuits. The total power in a three-phase balanced circuit, i.e., power delivered by a three-phase generator or absorbed by three-phase load is determined by adding the power in each of the three phases. In a balanced circuit this is the same as multiplying the power in any one phase by 3 since ...

      Power in a three-phase system is constant rather than pulsating and three-phase motors start and run much better than single-phase motors. A three-phase system is a generator-load pair in which the generator produces three sinusoidal voltages of equal amplitude and frequency but differing in phase by 120( from each other.

      The power company will specify where in the system their responsibility ends. The data needed is the line to line voltage (VLL), short-circuit kVA (kVASC), and X/R. Obtaining the voltage is simple enough. Short-circuit kVA is the power available at a bolted three phase fault. Bolted means all three phases connected together with no added impedance.
