Title: Power in AC Circuit
Post by: nusrat.eee on July 14, 2019, 07:42:54 PM

AC circuits are usually three-phase for electrical distribution and electrical transmission purposes. Single phase circuits are commonly used in our domestic supply system.

The total power of a three-phase AC circuit is equal to three times the single phase power. So if the power in a single phase of a three-phase system is ‘P’, then the total power of the three-phase system would by 3P (provided the three-phase system is perfectly balanced). But if the three-phase system is not exactly balanced, then the total power of the system would be the sum of the power of individual phases.
