Abstract :
Based on the circuit theory, this paper adopts the analysis model for the impulse characteristics of grounding device considering the nonlinear soil ionization phenomena in the soil neighbouring the grounding conductors. The impulse characteristics of a typical independence grounding device for lightning protection of electronic and electrical systems inside structures is discussed and the impacts of interval and length of vertical rods, and soil resistivity are also compared by the use of this model. Suggestions for the layout of this grounding device are proposed according to the calculated results.
