Abstract
It is widely known that the ultra high frequency (UHF) method that detects the electromagnetic wave of the PD pulses in the gas insulated space is one of the most competitive methods for its high sensitivity. From the above point of view, this paper describes the noise suppression methods and the PD measurement results of the in-service substation by the developed UHF PD measurement system which consists of the external UHF coupler, the UWB LNA and the digital storage oscilloscope. As results, it was found that the effect of the noise suppression methods were verified and that the developed external UHF coupler showed a better detection sensitivity than a conventional external coupler.
