| Abstract: | The partial discharge live detection of GIS can detect the problems like internal bad contact,insulationdegradation,it can prevent the defect moving forward and guarantee the safe operation of equipment and the system.The principal of ultrahigh frequency and ultrasonic method and the application in partial discharge live detection ofGIS are introduced,and the application case in 500kV transformation station is illustrated. In the case,the dis-charge type is classified with discharge waveform and the discharge location is determined with the amplitude loca-tion method and time difference location method. The detection and analysis are verified by the offline disassembly of the equipment. |
