Local Electric Field Analysis for Evaluation of Charge Transfer System Using Sequential Sub-window Techniq

유한요소법을 이용한 쌍극자 공간전하 방전분산형 피뢰침 정전유도구체의 국부전계 해석

In this study, in order to increase electric field intensify near a lightning rod a floating conductor is adopted. If a floating conductor is located near the lightning rod, the positive and negative charges are equally induced on the lightning rod and the floating conductor, and the local electric field intensity near them increases. This increase of electric field intensity can ignite easily the ionization process of the surrounding air and the corona phenomenon begins there. It occurs before the usual lightning process begins on the top of the conventional rod. The charges of the ground or some buildings are omitted during the corona process through the floating conductor. Therefore, the probability of the main lightning on the conventional rod can be reduced.
