Surge propagation on nonuniform conductors has been investigated on the basis of finite‐difference time‐domain (FDTD) simulations. It has been confirmed that an inclined conductor above the earth is represented following the image theory based on transverse electromagnetic (TEM) wave propagation by two angled (nonparallel) conductors in a free space. Nonparallel conductor systems above the earth show a wave propagation characteristic quite different from that of the TEM mode, and thus steady‐state and transient phenomena on the nonparallel conductors cannot be appropriately analyzed by a circuit theory and by simulation tools such as the EMTP based on the circuit theory. © 2016 Institute of Electrical Engineers of Japan.
