Abstract: According to the lightning electromagnetic field effects on transmission line,we put the lightning electromagnetic field in the transmission line equation understood as LC series parallel circuits,to calculate and analyze quickly and accurately the influence degree of the electric field on transmission lines. This study by using the equivalent circuit method on our deep understanding of lightning electromagnetic field on transmission line coupling mechanism is of great significance.

Key words: lightning, electromagnetic field, equivalent circuit method
