Abstract (2. Language): 
Nowadays over voltages caused by lightning in transmission line located in mountainous regions are very important in power system transient studies. This study aims to present and investigate modeling 400 KV single circuit transmission lines. Hence this study, the performed analysis for assessing single phase ignition and back flash over, three common models of the tower in transient studies including Multistory, simplified Multistory and simplified wide line models have been used. The paper illustrates the benefit of ATP / EMTP to finding the best type of line against the lightning. The paper has proven that for negative polarity of current wave, range of overvoltage caused by lightning is the lowest for the Multistory model, Moreover the paper considering the same negative polarity, range of voltages from arms to earth is the lowest for Multistory model. Also results of this study show that Multistory is better and more acceptable than the other two models for the studied line.
