Polyphase:
More than one meaning 2 phase, 3 phase, and 6 phase is called polyphase
Single Phase:
The alternator producing a phase supply consists of a vending. In this case, the value of voltage and current does not change
2 Phase:
The alternator producing two-phase supply consists of two vending. It is facing both ways in such a way that the phase difference between them is 90 degrees. Now if the value of the voltage between phase and neutral is 200 v, then two The phase voltage will be 200 * √2V
3 phase:
3 phase alternator is arranged in three ways so that the phase difference between them is 120 degrees. Now if the value of the voltage between a phase and neutral is 200 v then the voltage between any two phases = 200 * √3v will be
