Abstract

This research has studied a method to calculate the lightning tripping number of a transmission line by dividing this long line into many small units. In addition, the paper also considers the influence of design parameters and natural parameters of the line on the number of incidents caused by lightning on the tower positions of the line. From the calculation results, it can be seen that by considering all the above influence factors, the lightning tripping rate/lightning tripping number of the transmission line will be much higher than that using the average calculation method. Moreover, the number of incidents caused by lightning at different tower positions is so different. Therefore, when we need to reduce the lightning tripping rate or lightning incident number of a transmission line, it is necessary to calculate the lightning tripping rate or incident number at each tower position in order to propose appropriate solutions.
