tower[13]-[16]. However that can't be achieved by IEEE
FLASH program.
In this paper, The IEEE method is adopted, with
consideration of the actual structure of each tower,
lightning activity, geographical environment, insulation
coordination and other factors. The lightning performance
of six 500kV transmission lines in southern China is
analyzed with the help of Lightning Performance
Analyzing System for Transmission Line (LPTL)[17].
With comparative analysis of their operation experience,
an available method is proposed to assess the lightning
performance of 500kV transmission lines in southern
China.
