Paper: Lightning Protection of Electric Distribution Lines

This paper is a report of methods used by Southwestern Public Service Company to reduce momentary interruptions due to lightning. This required the determination of the optimum spacing of arresters to protect distribution lines from lightning by applying arrester stations to two different locations in the same area. Each line represents a different average spacing of arrester stations. These lines are compared to a shielded line and an unprotected line, also in the same area.
