This paper presents a methodology proposed in international literature by the IEEE std 1410 2010 like a guide to evaluate the effect of nearby lightning strokes on distribution lines, calculation induced transients and analysis performance of overhead distribution lines in EPM for a type of study. According to topology constructive of electrical network, there is a answer in the performance of overhead line; likewise, it is presented the results of a parametric study that determine the significant influence of the lightning's basic parameters in the induced transients originated in a overhead distribution network.
