| Abstract: | By means of on-line ultra high frequency (UHF) partial discharge (PD) monitoring system the catastrophic failures, which may occur in gas-insulated switchgears (GIS), can be prevented. In this paper the basic structure of on-line UHF partial discharge monitoring system and the partial discharge tests carried out in laboratory for the purpose of verifying this system are presented. In addition, two practical cases of applying this system to the substations in the Republic of Korea are given. Various UHF PD data in the environment of laboratory as well as on-site PD signals are stored in the database of this system, thus once this system is installed in substation, non-professional people can also judge the state of GIS. |
