This paper introduces the principle of detecting HV insulator states using uhra-violet ray emitted during insulator discharging. An on-line ultra-violet detecting method for HV insulator on high voltage transmission line is put forward. The structure and working principle of the on-line ultra-violet detector are also analyzed. Spark simulation experiment was carried out using the detector. Experimental result indicates that the detector features high sensitivity, quick response speed and high security. The proposed on-line ultra-violet insulator detector has bright application future.
