Gas Insulated Switchgear （GIS） is an important equipment of the power system transformer substation, however, its insulation fault will seriously disturb the security and stability of the system. The most common electrical failure is characterized by a partial discharge occurring before the GIS completely shut down. In this paper, Finite-Diffrenee Time-Domain algorithm （FDTD） is used to simulate the UHF signal in GIS partial discharge, and analyze the partial discharge characteristics. Compared to the measured UHF signal, FDTD algorithm is ...
