Three-phase electric power (abbreviated 3ϕ ) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power.

WhatsAppThree-phase electricity uses three conducting wires instead of one. It produces alternating current in three waveforms, separated by 120 electrical degrees, to ensure the electricity is constant. If that seems confusing, an easier way to think of that is that each of the three is separated by ⅓ of the time for a complete cycle (360°).
