Question

what will happen if two fuses of a 3 phase induction motor blow off during run?​

Answer 1

Answer:

A phase failure is an interruption of a single conductor. The motor then continues running with two phases and can suffer damage. The cause is, for example, blown fuse.

Explanation:

If a three-phase motor is operating and loses one of the phases, the motor will continue to operate at a reduced speed and experience vibrations. The current will also increase considerably in the remaining phases, causing an internal heating of the motor components.
