What happen if we re-start H.T motor whose rotor is running at 40% rated speed. Is it will damage motor winding?

If an induction motor is restarted before its rotor stop rotating, then what will be the amount of current drawn? Is this current will be the same as motor starting current?

without any theoretical calculations, can u approximately tell the current rating of a motor(above 30hp)working at 415VAC.

what is meant by negative sequencing in power system.explain in detail
