There are two types of systems available in electrical, single-phase and three-phase circuits. In the single-phase circuit, there will be only one phase, that is, the current will flow through a single cable and there will be a return path called the neutral line to complete the circuit. So in single-phase minimum amount of energy can be transported. Here the generator station and the charging station will also be single-phase. This is an old system that has used since earlier times.
In 1882, a new invention has been made in the polyphase system, which can be used more than one phase to generate, transmit and for the charging system. The three-phase circuit is the polyphase system in which three phases of the generator are sent to the load.
Each phase has a phase difference of 120 °, ie 120 ° of angle electrically. Thus, of the 360o total, three phases are equally divided into 120o each. The power in the three-phase system is continuous since all three phases are involved in the generation of total power. The sinusoidal waves for the 3-phase system are shown below:
The three phases can be used as a single phase each. So if the load is single-phase, then you can take a phase of the three-phase circuit and the neutral can be used as ground to complete the circuit.
