The UHF method is widely used in online diagnosis of partial discharge in the gas insulated switchgear (GIS). The UHF method is based on the detection of the EM wave which is excited by the partial discharge. It's important to study the EM wave propagation characteristics in GIS.
Based on finite element method (FEM), the propagation characteristics of EM wave which propagates in the GIS structure are studied. A high precision model of GIS for analyzing EM wave was established based on a practical GIS b...
