A Calculation Method and Analytical Formula of the Earth High Frequency Zero Sequence Impedance

Songhai Fan, Linjie Fang, Yusheng Quan


This paper puts forward a method of calculating the high-frequency zero sequence impedance, and deduces the earth high frequency analytic calculation formula for the zero sequence impedance. In order to verify the validity of analytical formulas, this paper combined with a large field trial data. Analytic calculation formula in this paper, with simple forms and convenient application, will contribute to the analysis and calculation of lightning and transient characteristics of overhead transmission lines.
