Soil Resistivity Lightning Current Model

Abstract:

Lightning protection dependents on the lightning current. According to the discharge characteristics of lightning current and the soil resistivity with different areas in Yunnan, the relationship between the earth resistivity and lightning current model was put forward. And comparison of the existing double exponential model, Holder model and impulse function model, then lightning parameters were analyzed. The soil resistivity model not only conforms to the lightning parameters measured in American, but also obtains the relationship among lightning current, the soil resistivity, the radius of the channel, and the response speed. The results provide fundamental theory for the research of lightning current.
