摘要
Abstract
The detection methods for inter-turn short circuit fault of generator rotor are various, but most of them are not sensitive enough to detect small inter-turn short circuit faults. The paper introduces a convenient and sensitive method for inter-turn short circuit faults detection, namely the RSO technique, and it also intro-duces the operating principle and advantages. In an electrochemical impedance spectroscopy (EIS) test of 660 MW thermal power generating units, it is preliminarily determined that there is inter-turn insulation fault in the rotor; by using RSO test method, the fault is diagnosed and located, and the diagnosis result is verified through endoscope examination.关键词
