Study on cause analysis and detection method of inter-turn short circuit fault of large turbine generator rotor – presentation

1. The RSO is sensitive and accurate in the diagnosis method of the insulation failure between the rotor turns in the shutdown state.
2. The detection coil waveform method is accurate and effective. It is recommended that the power plant be equipped with a detection coil sensor, which is carried out regularly during operation.
3. Other methods, such as operating parameter comparison method, AC impedance method, etc., can be used as auxiliary methods for fault diagnosis.
