Abstract
Among the power system overvoltages, switching overvoltages are analysed in this paper, using EMTP(Electro-Magenetic Transient Program ) and TNA(Transient Network Analyzer ). From this analysis, the switching overvoltages are used to determine the BSL(Basic Switching Withstand Level) and the clearance of the transmission tower. Up to now the switching overvoltages were analysed by EMTP, but in order to determine the more exact value of BSL, not only digital but also analog method is required.
