Abstract :
IT IS OFTEN DESIRABLE to test the effectiveness of the interlaminar insulation in a generator stator. Iron damage may be sustained as a consequence of mechanical abrasion or arc burning during a winding insulation failure. A simple flux test can be made to determine if the interlaminar insulation has been impaired within a damaged area which might develop into a hot spot when the machine is restored to service.
