| Abstract: | The inner ultra high frequency discharge sensor is widely used in GIS partial dischargedetection for the advantages of high sensitivity and strong anti-interference. However, the manufac-ture and installation of the inner sensor has the high demands, in the operation process, the imperfectinstallation technique may cause the discharge defection of the sensor itself. Aiming at the problem ,the suspended defection at the contact place of inner ultra high frequency discharge sensor is locatedin 363 kV GIS equipment by the method of partial discharge live detection, and the causes wereanalyzed. Finally the solutions were presented. |
