Section outline

  • Introduction:


    A single-phase AC power system consists of a generator connected through a pair of wires to a load. It contains two identical sources that are connected to two loads by two outer wires and the neutral. Circuits or systems in which the ac sources operate at the same frequency but different phases are known as polyphase. A three-phase system is produced by a generator consisting of three sources having the same amplitude and frequency but out of phase with each other by 120 degrees.
