WebThree-phase electric power is a common method of electrical power transmission. It is a type of polyphase system mainly used to power motors and many other devices. A three-phase system uses less conductor material to transmit electric power than equivalent single-phase, two-phase, or direct current (DC) systems at the same voltage. WebThe three-phase system consists of a three-phase voltage source connected to a three-phase load by means of transformers and transmission lines. Two types of connections are possible, namely delta (Δ) connection and star or wye (Y) connection. The load and the source can be either in delta or star. The transmission line will be in delta connection.
