Background
Faults and damages of rotating electric machines are mostly caused by damages of the winding insulation, wherein the turn-to-turn insulation of the winding takes up about 50% and the consequences are severe once damaged. The turn-to-turn insulation short circuit is basically caused by the fact that the turn-to-turn impulse voltage value of the motor exceeds the working voltage of the turn-to-turn insulation of a part of windings under various overvoltage actions, a part of the short circuit is caused by mechanical damage of the coils and the windings in the manufacturing process, and in addition, the short circuit is caused by partial discharge generated by the internal gaps of the high-voltage motor windings and corona corrosion of the high-voltage windings.
