Lightning Performance of Non-Homogeneus Overhead Distribution Lines

Traditionally, on lightning induced voltages studies, distribution lines haven been considered with equal features along the line; the reality in many places is that distribution lines contains differences in its route that it is important to take them into account. In this paper, the effect of unequal heights of each pole, unequal insulation level and unequal ground resistances along the line will be considered in the calculation of the lightning performance of these lines. Some relevant conclusions will be presented.
