Abstract

This paper presents the influence of the lightning overvoltage and the shielding effects of overhead grounding wire on the DC railway system. Modeling of Railway system is established in ATPDraw to perform simulation. The result of simulation reveals that the shielding effects of overhead grounding wire has over 90% than the case which has not it. Therefore it is evaluated that overhead grounding wire should be installed in the DC railway line.
