Abstract

<abstract abstract-type="main"> <title>SUMMARY</title> <p>In this paper, representations of a perfectly conducting thin wire and an imperfectly conducting medium in the transmission line modeling (TLM) calculation are briefly explained. Then, the method is applied to analyzing surge responses of a vertical parallelepiped grounding electrode and a square‐loop grounding electrode. Surge responses calculated using the TLM method agree reasonably well with the corresponding responses measured and calculated using the finite‐difference time‐domain method. It is probably the first time that surge responses of grounding electrodes have been analyzed reasonably accurately using the TLM method.</p> </abstract>
