Abstract：In this paper, an analytical method of the Time-Frequency characteristics of horizontal electrode under lightning strike is presented based on EMTP, a transmission line model of horizontal electrode with the consideration of soil ionization is designed. It is easy to analysis the time-domain characteristic of horizontal electrode by using this model. Moreover, the impulse current and voltage are transformed by FFT analysis, then, the frequency impedance and effective length of horizontal electrode can be calculated, furthermore , the relationship of the magnitude and rise time of lightning with the frequency impedance can be gained.
