Abstract

In this paper the indirect-lightning flashover rate of a distribution line is obtained following the procedure described in the IEEE Std. 1410 – 2010, but using other parameters of the first stroke distributions (peak current and front time) adopted by CIGRÉ.  These parameters were taken from the measured currents of the Morro do Cachimbo Station in Belo Horizonte – Brazil, which are representative of the tropical zone.  As a result, the calculated flashover rate with the data of tropical zone is higher than one obtained with the CIGRÉ curves. Such increments could be in the most extreme case of 70%.
