Abstract :
In this paper, a measuring system for detecting partial discharge of generator stator bar based on ultra-high frequency method has been designed, and the test results in laboratory show that partial discharge in generator stator bar can be detected by this method. Furthermore, the results of on-line detection of power generator indicate that the ultra-high frequency method has the ability of detecting partial discharge without external interference coming from the exciter or transformer.
