Abstract

This paper describes analytical method for calculation of probability of appearance of certain values of phase to ground overvoltage which is caused by direct lightning stroke. The computer program for calculation of those probabilities is also explained and applied. Influences of the position of direct lightning stroke as well as influences of some line parameters on probability of appearance of certain value of phase to ground overvoltage are described and analyzed.
