Parametric Analysis of the Lightning Performance of Overhead Transmission Lines Using an Electromagnetic Transients Program

This paper presents the application of the ATP package to the study of the lightning performance of trans- mission lines using a statistical approach. The study is based on the use of the electrogeometric model and the application of the Monte Carlo method. Parametric studies have also been performed to determine the sensitivity of the flashover rate with respect some parameters of the transmission line and the return stroke.
