Abstract
It has been well known for many years that grounding resistance has a current-dependent characteristic due to soil ionization. Moreover reinforced concrete poles should be treated as a kind of grounding electrode against lightning strokes. However, these characteristics were seldom taken into account for lightning-protection designs. If these characteristics are represented in EMTP models for lightning protection designs, the rationalization of the lightning protection designs for distribution lines is expected.<br>In order to clarify transient behaviors of a system of a grounding electrode and a concrete pole, experiments were conducted with full-scale grounding systems. In this study, the paper described a composite model of a reinforced concrete pole and a grounding electrode for distribution lines and compared the calculated waveforms with measured waveforms of the experiments. The results show that it is necessary to take a current-dependent characteristic into account and treat concrete poles as a kind of grounding electrode.
