Question

Explain the necessity of starter.

Answer 1

Answer:

The three phase induction motors are self-starting due to rotating magnetic field. But the motors show tendency to draw very high current at the time of starting. ... Hence there should be a device which can limit such high starting current. Such a device which limits high starting current is called a starter.
