In this paper, a new method for obtaining partial discharge (PD) characteristic based on ultra-high frequency (UHF) measurements is presented. According to electromagnetic theory, the PD electromagnetic radiation can be regarded as the dipoles radiation. Based on which, the radiation model of partial discharge pulse current is established. The waveform parameter of PD pulse current can be obtained...
In this paper, a new method for obtaining partial discharge (PD) characteristic based on ultra-high frequency (UHF) measurements is presented. According to electromagnetic theory, PD electromagnetic radiation can be regarded as the dipoles radiation. The PD pulse current waveform can be deduced from its radiating UHF signal, based on which, PD characters such as the apparent discharge quantity, waveform...
