Calculation of lightning flashover rates of overhead distribution lines, a comparative study

The estimation of the lightning performance of overhead distribution lines presents many uncertainties due to the random nature of the lightning phenomenon and the lack of reliable data. Because of this, simplified methods to calculate the number of flashovers in an overhead line can be very useful and as effective as a rigorous simulation with advanced models. This paper presents a comparative study of some approaches proposed for calculating lightning flashover rates of overhead distribution lines.
