Three-phase electric power - Wikipedia

WebThree phase AC power is the most common form of industrial voltage service. Polyphase power is produced and consumed with care given to balance the various legs to preserve power quality. “Polyphase” means “many phases,” describing a form of AC electrical system where multiple sinusoidal voltages exist that are not in step with each other. WebThe current which changes its directions periodically, such type of current is called alternating current. Their magnitude and polarity also change along with the time. In such types of current, the free electrons (electric charge) moved in the forward as well as in the backwards direction.
