A new approach to partial discharge testing of HV cable systems
TLDR
In this article, the authors describe the application of an innovative partial discharge detection and analysis approach to the diagnosis of HV polymeric cable systems and present the results of PD measurements performed off-line on cable systems, rated from 220 to 400 kV.Abstract:
This paper describes the application of an innovative partial discharge (PD) detection and analysis approach to the diagnosis of HV polymeric cable systems. The results of PD measurements performed off-line on cable systems, rated from 220 to 400 kV just after laying or after some time in operation, are presented. PD generating defect identification and location are discussed, also in relation to forensic observationsread more
