Statistical Analysis of Lightning-Induced Voltages in Case of Linearly Rising Channel-Base Currents and Lossy Ground

This paper proposes a statistical analysis of the lightning-induced voltages on overhead lines in case of lossy ground. The analysis, which assumes three random input variables, namely channel-base current peak value, front time, and line to strike distance, allows identifying parametric distributions able to describe the statistical behavior of the lightning-induced voltages; the lightning performance of the line is evaluated, too
