A polyphase network is a type of electrical power distribution system that uses multiple phases of alternating current to transmit power. In a polyphase network, the power is distributed through two or more wires, each carrying an alternating current that is out of phase with the others. The most common type of polyphase network is the three-phase system, which uses three phases of alternating current that are 120 degrees out of phase with each other. Polyphase networks are widely used in industrial and commercial applications because they are more efficient and reliable than single-phase systems. They are also used in high-power applications such as electric motors and generators, where the use of multiple phases can reduce the size and cost of the equipment.
