Abstract :
In this paper, the effect of soil ionization due to lightning strike on wind turbine grounding electrodes is investigated. The developed ionization model is validated and subsequently used to investigate the influence of several parameters on the phenomenon studied, namely, the soil type, the electrode type and the crest value of the impulse current. All simulations are performed using EMTP computer program.
