Lightning induced voltages on power lines: a new statistical approach

The indirect lightning performances of distribution lines are related to two main aspects: the induced overvoltages calculation and the statistical treatment of the obtained results. In the paper, both the aspects are treated. In particular, an exact closed form solution will be used to calculate the induced overvoltage, and the consequent statistical treatment will be carried out taking into account all the random parameter involved in the analysis, which is a more complete approach with respect to the usual one adopted in literature.
