Abstract
In the article the analysis of the proportion of lightning strikes in the towers and the upper phase wire of the span of overhead transmission lines without ground wire, made in accordance with different applicable in the Russian Federation, regulatory documents of lightning. Built zone protection of the towers on transmission lines lines without ground wire depending on the span length and the height of the towers. Seem significant differences of the results of assessments by different techniques. The results of the builds were revealed the need to refine existing methods to determine the fraction of lightning strikes in the towers and phase wirles.
