I want to discuss a practical case of three phase induction motor.
Due to faliure in H.V three coils have been by passed out of 120.And a high no load power is taken from motor,specifiacly 68% more than it should.No load power is increased by 3Amps which is okay.There are 4 parallel paths in the machine.
I want to know the exact reason why this much no load power is taken.
Also do the bypassing of coils increase the magnetic noise?
