Influence of Lightning Channel Impedance and Nonuniform Tower Footing Resistance Distribution on Line Surge Arrester Energy Duty
This paper describes a detailed transmission line model for a transient analysis. Line surge arrester energy sharing and importance of complete transmission line modelling is explained. Lightning channel impedance and tower footing resistance are important parameters that influence line surge arrester energy duty. Therefore, energy stresses of transmission line surge arresters due to different values of lightning channel impedance and nonuniform distribution of tower footing resistance are considered.
