Abstract

This paper presents the induced voltages produced by a lightning that hits the top of a mountain over a line placed parallel to the inclined surface, compared with the result found when the line is placed over a flat terrain. The electromagnetic fields produced by the lightning channel are calculated by means of the Finite Difference Time Domain Method (FDTD) and the lightning induced voltages are calculated with the Agrawal approach. This work shows that exists important differences in the lightning induced voltages when we take into account the topography.
