| Abstract: | In order to analyze the wave process of the transmission tower struck by lightning,the equivalent model of a transmission tower was studied.Based on the correlative theory of taper antenna,the equivalent wave impedance model of a single tower stanchion was also studied.Firstly,the tower was regarded as a four-conductor system in consideration of the fact configuration of a tower,the equivalent wave impedance of the four-conductor system was derived from a single vertical conductor.Secondly,considering the d... |
