Abstract :
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.
