With the development of the power industry, the scale of the power grid is also expanding. Lightning strikes on high-voltage overhead lines also occur frequently, because it is more and more important to improve the lightning protection of high-voltage overhead lines in North China. In this paper, an overseas power grid accident caused by lightning strike is analyzed in detail, and the defects of lightning protection for overhead high voltage lines in China are analyzed statistically. Based on this, the improvement measures of lightning protection for overhead high voltage lines are put forward.
