Abstract. This paper presents simulation results of the electric field distribution along composite insulators used in I, II and V strings suspension and dead-end towers in 400 kV AC power transmission lines in Algeria. A two-dimensional model is built using COMSOL Multiphysics software based on the Finite Element Method. Corona rings are considered on both line and ground ends. Their parameters (ring radius, tube radius and distance from both ends) are kept invariable throughout the analyses. The impact of conductors and ground structure, insulator orientation (suspension and dead-end) and insulators surface state condition (dry and polluted) on the electric field distribution has been analyzed. General conclusions are displayed such as that the dead-end insulators experience higher electric field compared to those used in suspension lines. Finally, the influence of impulse voltage on the electric behavior of insulators is investigated.
