The PD on-line monitoring method of high voltage transformer in nuclear power plant is introduced by the authors in this paper.The principle of different partial discharge detection methods of transformer is discussed.The different technologies are analyzed and compared.The method of transformer partial discharge detection and location analysis is researched.

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.
