Abstract
Partial discharge detection is a key technological means for gas insulated switchgear state diagnosis at present. This paper analyzes various partial discharge detection methods and considers that ultra-high frequency is provide with stronger anti-jamming capability and higher detection efficiency which may realize fault mode recognition and positioning. On the ba-sis of the above analysis,one GIS typical suspended discharge defect was discovered by applying partial discharge ultra-high frequency detection method. Afterwards,ultra-high frequency time-of-arrival location was used to ensure defect position and phase synchronous technology was used to confirm defect phase. By strip inspection,the result was verified agreed with diagnosis result of ultra-high frequency method.关键词
