Abstract

A two-dimensional finite-element model for potential and electrical-field calculation along an ice-covered composite insulator is presented. To find the influence of the ice on the potential and electrical-field distribution, various thicknesses of the ice and various lengths of the icicles are simulated in the condition of dry ice and wet ice, respectively. In addition, the present study investigates the influence of the discrete water film and the dry band on the potential and electrical-field distribution of the iced composite insulator. Finally, a comparison between the electric-field distribution along the ice-covered composite insulator and that of ice-covered ceramic insulator string is presented.
