Title: Investigation on the Lightning Withstand Level in Case of Lightning Striking to the Tower Top with Consideration of Power Frequency Voltage
Abstract: Lightning withstand level is an important parameter in estimating lightning protection ability of the transmission line,1it effects the reliability and security of the power system.Regular method is used to research the influence of a.c.operating voltage on the lightning withstand level in case of lightning striking at the top tower with the voltage level varying from 110 kV to 500 kV.The results show that the effect of a.c.operating voltage on the lightning withstand level at lightning striking to the tower top of high voltage line enlarges with the increase of the voltage level.Thus the power frequency voltage must be considered in the designing of the HV and EHV lines.
