Abstract CAD manufacturing features based modeling method is used in studying propagation of EM-field in gas insulated switchgear(GIS). We take inverting mode to simplify the model of GIS step by step. A precision analysis model was established based on a practical 252kV GIS blueprint, and the frequency characteristic of EM leakage has been simulated using the finite element method. Different levels of simplification based on manufacturing features were carried out on this practical GIS. After systematic comparison, the influence of manufacturing feature simplification on computation of leakage of EM-wave was studied. The balance between the calculation accuracy and computing speed is considered. The results offer a scientific and systematic simplification method for calculating EM leakage of the GIS for further GIS design or simulation. Because the construction processes of feature modeling and EM model are the same, the presented method for modeling GIS has general purpose.

Key words： Gas insulated switchgear(GIS) leakage of EM-wave propagation characteristics of EM model simplification finite element method(FEM)
