Lightning performance improvement of 132 kV transmission line by using line surge arresters

Abstract

Lightning is a natural phenomenon and this condition of lightning surge may cause the travelling waves and cause the temporary increase in voltage in the transmission line system. The line voltage increase is harmful because it can destroy the equipment in transmission line system. One of the methods to improve the lightning performance of transmission lines in services is by applying the transmission line arresters. Therefore, it is necessary to analyze such as the increase voltage in order to design surge arrester that suitable for investment and select the best configuration to ensure the good performance for lightning performance improvement in transmission line system. One of the applications of ATP/EMTP simulation software are design, analyze and study the lightning activities and performance in 132 kV transmission line circuit. J.Marti model is one of the overhead lines model while Heidler model is used for simulation for fast front lightning surge. Tower model for this study is referred to model proposed by Masaru Ishii. Therefore, it is important to analyze the surge arrester configuration for the good performance of the transmission line system. The best lightning performance is configuration produced zero backflashover voltage and used less transmission line arrester.
