Motor starting methods. (DOL. Assisted Start, Soft start Star/Delta With PLC Ladder Diagram )?

Question

Electrical

Answer 1

DOL staring if for low capacity motor ,preferably up to 5 hp.At the time of starting the current will be high  and may cause the system in trouble.That is why direct on line staring is used for low capacity motors

The star delta starter is used to limit the starting current.Start with a star connection and then put in delta will not cause the current to go high.if it is not done ,the fuse/relay may act,separating the circuit.
