Abstract:In this paper, the electric field is calculated by the finite element method. By calculation and analysis of the 500kV AC transmission lines model, this paper draws a conclusion that the electric field intensity is less than the national standard limit at 1.5m above the ground. In the calculation, the mesh generation with the freedom coupling method on interfaces is adopted to model the thin transmission lines and the large surrounding air region, and is appropriate for calculating electric field of transmission lines. This method is able to reduce the demand of element numbers and increase the calculation accuracy heavily.
