Abstract

This paper proposes a simple transmission line model adopted with the partial element equivalent circuit (PEEC) method for lightning surge analysis. The proposed approach is employed for calculating tower surge responses and voltages across insulators of an actual transmission tower. The proposed approach increases the efficiency of the method in terms of computation time because of reducing a number of elements in the PEEC method. Comparisons of the simulation results by the proposed approach in the time domain, and by the PEEC method without a transmission line model and available experimental data shows satisfactory agreement not only for amplitudes but also for waveshapes.
