Abstract:
In this paper, lightning performance of overhead lines based on different models of tower-footing vertical rod and tower is investigated. As we know, there are a number of models for vertical rods and tower from low-frequency to highfrequency.Hence at first overhead lines, tower, and vertical rod (with different models) are imported into electromagnetic transient program (EMTP), and lightning-induced voltage along lines are thencomputed. The obtained results show that the wide-band models in comparison with lowfrequency models results in considerable effects on the induced voltage.
