Abstract :
Electro-geometric (EGM) model is now the most popular method for the shielding failure flash-over rate (SFFOR) calculation. In this paper, the Lightning protection theory of the negative angle protective pin is studied on basis of this method, and Installing the negative angle protective pin on the hillside or the peak of the 35 kV transmission line in order to reduce the ground shielding failure which is the main cause of lightning flash-over of 35 kV transmission lines in DeXing Copper Mine in Jiangxi Province. It was suggested that this research must be considered as one of the important factor in the lightening protection of transmission lines.
