Abstract: Lighting Phenomena is one of the important considerations during the design of Extra High Voltage and Ultra High Voltage Transmission Lines. Most of the authors have discussed regarding the benefits of using Surge Arresters as a way to improve the performance. In this paper, simulation analysis is done on 400kV/220kV Gwaka Substation, AP, India for optimal, cost effective placement of surge arresters. The most difficult configuration has been identified. A new method of “Voltage-Distance curve” is proposed to evaluate different Surge Arrester installation configurations. Finally the way to determine the optimal surge arrester configuration for each line section is then introduced in this paper.
