Lightning Stroke Shielding of Electric Railway Overhead Catenary Feeding Systems

This paper describes shielding of overhead power feeding systems for electric railway. Some additional shield wires are determined to prevent lightning flashes from terminating on phase conductors. The electro-geometric model is employed in order to find the perfect shielding angle where the location of the shield wires is optimized according to the guide of IEEE T&D committee. A typical double-track railway overhead catenary feeding system is examined.
