Surge Arresters

Surge arresters are commonly applied across all system voltages to protect critical equipment insulation from failure due to high voltage surges. This paper presents the effectiveness of applying polymer housed line surge arresters to eliminate momentary interruptions caused by lightning.

The appropriate selection and design of a line surge arrester is critical to ensure proper protection and performance are achieved. Utilizing line surge arresters can serve as an economical alternative to retrofitting lines with an overhead shield wire or completely rebuilding a line. Using this technology can improve performance, while also extending the useful life of valuable assets.
