A Study on the Electric Field Analysis of Extra-High Voltage Oil-Filled Cable Accessories

This paper presents an algorithm for electric field analysis which is essential to insulation design of extra-high voltage oil-filled cable accessories using finite element method. Governing equation is induced by electromagnetic equation. Variational method is adopted for FEN formulation. Automatic mesh generation which saves time and labor is introduced for the input data. The application results of proposed algorithms were used for insulation design to develop 345kV cable joint.
