Research on Characteristics of Surface Electric Field on Transmission Lines under Lightning Stroke

摘要：

Lightning is a major cause of power interruptions in power transmission lines.Nowadays the Leader Progression Model is an advanced method to evaluate the shielding failure probability of transmission lines.Calculating the surface electric field on phase conductors and ground wires precisely is important, because the surface electric field has great effect on the upward leader inception.In this paper, the influence of lightning current and some other factors on surface electric field were analyzed.
