Abstract
UHF PD sensor has some disadvantages in measuring void discharges due to their frequency characteristics lower than 300MHz. Therefore, in this study, the possibility of VHF sensor in measuring partial discharges(PD) in GIS was investigated using simulated experiments. As a result, by installing VHF sensors to the copper bus of the encloser in GIS, it is confirmed that partial discharges could be perfectly detected, which means that VHF PD measuring technique can be the alternative of UHF PD method.
