| Abstract: | According to operating characters of 500 kV oil-filled cable of a storage power station,the integrated scheme of on-line partial discharge monitoring system for 500 kV oil-filled cable is presented in this paper.Moreover,the all hardware and software of system are developed.The system had been applied on the AB link line terminal of a station of the storage power station.The monitoring results indicate that the system not only can calculate and display seven discharge parameters exactly,but also can display four charts,furthermore,can estimate discharge states of insulation effectively. |
| Keywords: | oil-filled cable partial discharge on-line monitoring |
