چکیده:

Lightning is one of the most important causes of over voltage disturbances in the DC Light Railway Transportation (LRT) system, which, its effect is not considered, would cause serious problems for devices, staffs and passengers. Lightning arrester is a useful device to eliminate and mitigate this problem. In this paper the effect of lightning strike on LRT is analyzed in two cases: including surge arresters installed in different locations of electrical DC supply and without arresters. Simulation results carried out with ATP software is presented for both cases. It is assumed in this paper that the lightning dose not strike the DC line, directly.
