Title: An integrated backflashover model for insulation coordination of overhead transmission lines
Abstract: The lightning performance of overhead transmission lines is measured with the probability of backflashover. This probability is affected by (a) tower type, (b) grounding arrangement, (c) soil resistivity and (d) lightning activity and lightning parameters of the area. This paper presents an integrated model of the transmission towers, tower grounding and overhead line conductors. The model is utilized in a Monte Carlo simulation for the purpose of predicting the lightning performance of a transmission line. This paper presents the models and the simulation method. Typical results for typical transmission towers and grounding arrangements are provided. The model reveals that the grounding arrangement as well as the surge impedance of the transmission tower are important parameters affecting line performance.
