three phase charging
Three-phase electric power (abbreviated 3ϕ) is the most widely used form of alternating current (AC) for electricity generation, transmission, and distribution. It is a type of polyphase system that uses three wires (or four, if a neutral return is included) and is the standard method by which electrical grids deliver power around the world.
In a three-phase system, each of the three voltages is offset by 120 degrees of phase shift relative to the others. This arrangement produces a more constant flow of power compared with single-phase systems, making it especially efficient for transmitting electricity over long distances and for powering heavy loads such as industrial machinery. Because it is an AC system, voltages can be easily increased or decreased with transformers, allowing high-voltage transmission and low-voltage distribution with minimal loss.
Three-phase circuits are also more economical: a three-wire system can transmit more power than a two-wire single-phase system of the same phase-to-phase voltage while using less conductor material. Beyond transmission, three-phase power is commonly used to run large induction motors, other electric motors, and heavy industrial loads, while smaller devices and household equipment often rely on single-phase circuits derived from the same network.
Three-phase electrical power was first developed in the 1880s by several inventors and has remained the backbone of modern electrical systems ever since.
