Effective length of horizontal grounding electrode

Abstract

In this paper, the influences of the length of grounding electrodes on the lightning transient characteristic were analyzed. The effect of effective length of grounding electrodes is demonstrated for 2.6/50 µs and 4.5/50 µs time duration of the wavefront. The effect of the soil ionization has been taken into account by dynamic change of the radius of the grounding conductor.
