HVACR (Heating, Ventilation, Air Conditioning / Refrigeration) How To Check 3 Phase Power For An Air Conditioner Or Refrigeration System (Electricity101) How To Check For Three Phase Electricity / 3 Phase Electrical Troubleshooting / Check 3 Phase Power With A Multimeter 208-230 Volts AC
Three-phase electric power is a common type of alternating current 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.
Three-phase electrical power was developed in the 1880s by multiple people. Three-phase power works by the voltage and currents being 120 degrees out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency.
A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Three-phase power is mainly used directly to power large induction motors, other electric motors, and other heavy loads. Small loads often use only a two-wire single-phase circuit, which may be derived from a three-phase system.
