Insulation failure prediction in AC machines using line-neutral voltages

This paper presents a novel technique to detect insulation failure in polyphase AC machines. The machine must be star connected and have the neutral accessible. The mathematical theory of the technique is provided and supported by an experimental validation-turn faults in the stator of an induction...
