Inspection and Treatment of Interturn Short Circuit of Hydraulic Turbine Generator Magnetic Pole Coils

This paper puts forward that the interturn insulation damage failure of magnetic pole coil accounts for a larger percentage in failures of hydraulic turbine generator sets of various water power stations at normal operation, and it often becomes serious safety hazard. Therefore, it is crucial for prevention, inspection and treatment of rotor interturn short-circuit failure by a quick and correct method. Several common interturn short-circuit situations and treatment methods of rotor magnetic pole coils are briefly described here by practical example. It provides some reference.
