Abstract

Disturbances to power distribution lines are mainly caused by lightning. Due to the random nature of lightning, the estimation of overhead distribution lines lightning performance is obtained by statistical methods. This paper investigates the influence of the return stroke velocity and the statistical method used to estimate the indirect lightning flashover rates of overhead distribution lines.
