Abstract

Partial discharge (PD) detection is significant to the insulation diagnosis in gas insulated switchgear (GIS). The ultra-high frequency (UHF) method was proposed for PD detection, and has been proved to be effective and applicable. However, it is difficult to calibrate the apparent charge quantity in partial discharge detection. This paper deal with the relationship between time-frequency representation of PD-induced UHF signal and PD current pulse. A simulation model of GIS is built based on Finite Difference Time Domain (FDTD) method. The time-frequency representation of different UHF signal induced by Gaussian pulse with different discharge length, pulse current amplitude and pulse width are compared. It is effective to detect the charge quantity in partial discharge.
