Compared to single phase power, three-phase power has many advantages. Three-phase transmission lines require fewer wires than an equivalent set of three single phase lines. For single-phase power, the instantaneous power delivered to a load pulsates, but for three phase power, it is constant, which decreases generator vibration and increases ...
