According to the research of l0kV distribution line located at Shaoyang mountainous regions,it is found that the coordination weakness between lightning protection and insulation defects.The reasons of lightning damage differences under different topography were analyzed based on the finite element simulation software,and appropriate simulation model was set up.The simulation results show that lightning damage for distribution lines and topography are closely related.The distribution lines,which hill inclination is greater or the soil resistivity is lower,the lightning damage is more frequent ...
