In order to ensure power supply reliability and reduce a variety of power supply failure, we analyze the development status, advantages and disadvantages of partial discharge detection techniques about the various Gas -insulated Metal-enclosed Swith Gear (GIS). We put forward the application of ultra high frequency (UHF) technology for GIS partial discharge online monitoring technology methods to solve the problems of the difference of the pulse current method of anti-interference ability and ultrasonic sensitivity the problem of low. According to the deficiency of the traditional ultra high frequency sensor, we developed a new window type of ultra high frequency sensor, and compared with conventional in vitro type UHF sensor. Experimental results show that that the window-type UHF sensor sensitivity and anti-jamming capability are superior to conventional high-frequency sensor
