Abstract: Introduction was made to the model and categories of transformer partial discharge, as well as the online detection technology of partial discharge signals. Aiming at the fault diagnosis of transformer partial discharge, this paper designed a kind of expert system of transformer partial discharge based on fuzzy reasoning. This system was built on the traditional expert systems and fuzzy reasoning unit. The results of simulation experiments show that the improved expert system greatly raised the recognition rate of four typical partial discharge signals, which provides a reliable method for partial discharge pattern recognition.
         Key words: partial discharge; fault diagnosis; fuzzy reasoning; expert system
