چکیده مقاله:
Line surge arresters used to improve transmission line performance when a lightning strike hits the shield wire or the top of a tower. In these studies, surge arresters location is very important. So, simulate these positions and predict the overvoltage caused by lightning current is essential. Therefore, should be choose some positions in order to obtain optimal performance. This paper done above study for all positions on a part of a high voltage 220kV double-circuit overhead transmission line to compare and evaluate the optimal positions. Therefore, the modified IEEE recommended dynamic model for surge arrestersis chosen. In order to do this study, EMTP-RV program is selected and the results are compared. Based on the simulations, recommendations for transmission line performance improvement are made
