Abstract: Lightning is one of the most significant source of overvoltages in overhead transmission lines. The lightning overvoltages could lead to failure of the devices connected to the transmission line. A fundamental constraint on the reliability of an electrical power transmission system is the effectiveness of its protective system. The role of the protective system is to safeguard system components from the effects of electrical overstress. Surge arresters are an important means of lightning protection in distribution systems. Therefore, it is necessary to analyze influence of such overvoltages in order to applying the line surge arrester for improving the reliability of transmission line system. The method used to analyze the increase in voltage due to lightning was done by using the ATP/EMTP software This paper is aimed at analyzing the lightning performance improvement of a transmission line after installing line surge arresters.
