Abstract
The aim of this paper was to study voltages on overhead single wire induced by lightning strikes to a tower located on a mountain, using the three dimension finite difference time-domain (3D-FDTD) method. The overhead wire is located at a close distance from the base of the mountain. The transmission line model extended to include a tall strike object was used to present the lightning channel and the tower. The case of the absence of the mountain is also analyzed. From the comparison between the two cases, it is shown that the induced voltages magnitudes and waveforms are significantly affected by the presence of the mountain.
