Abstract
This paper presents a 3D electric-field calculation model of the plusmn800 kV DC transmission line composite insulators based on finite element method. With this 3D model, this paper introduces the effect of the tower, transmission lines and the parameters of the corona rings on the potential and e-field distribution along the composite insulators, and optimizes the corona ring design in order to control the maximum e-field along the insulator surface and corona ring surface.
