| Abstract: | According to the data collected in the tripping site of 220kV Jiang- Long east transmission line such as the sizes of towers and poles, protection actuation and ground resistance etc., electrical geometrical model of shielding failure and the theory of back flashover lightning impulse withstand level were adopted. The causes of line tripping were analyzed together with lightning current values of lighming flash to earth provided by GPS lightning information system and the corresponding suggestions for improvement were proposed. |
