Application of a time-domain partial element equivalent circuit method to lightning surge analysis

摘要

This paper presents the application of a partial element equivalent circuit (PEEC) method neglecting retardation in the time domain for calculating tower surge responses and insulator voltages of an actual transmission tower, and transient performance of grounding electrodes. A comparison of the simulation results by the PEEC method in the time domain with simulation results calculated by a full-wave PEEC method in the frequency domain and experimental data shows satisfactory agreement not only for amplitudes but also for waveshapes.
