GIS is the most important equipment in power grid. Partial discharge is the main cause leading to insulation breakdown. UHF detection is an effective method for PD detection in GIS. It is significant to obtain the electromagnetic propagation characteristics for the accurate analysis of detection results. The FDTD algorithm is present in this paper to study the electromagnetic signal in GIS. The amplitude and frequency characteristics are studied in this paper.
