Abstract :
The line surge arrester with series gap can effectively improve the lightning protection performance of the transmission line, and guarantee its safe operation. This paper discussed the design of two different series gap structures, and their influence on the line surge arresters. The so-called "transverse discharge" between the grading ring of the insulator to the upper discharging electrode of the series gap is discussed. At last, the paper introduced the application and effects of line surge arresters in China. Line surge arresters have achieved good application effect, which have become the main lightning protection measures of transmission lines.
