Beschreibungen/Notizen

• We developed an Ultra high frequency (UHF) partial discharge fixed and portable monitoring systems to prevent a catastrophic failure of gas-insulated switchgears. The system has been tested in the laboratory and on-site for detection of various tested in the laboratory for detection of various UHF PD signals. We also performed detection sensitivity verification tests and compared them with conventional IEC60270 method. This system were verified a lot of instance which detect to failure on-site.
