Abstract 

Traditionally, the overhead transmission line  (OTL) can not function normally without special lightning protection. The article considers the main means and devices of lightning protection of OTL 110-750 kV according to the current normative documentation. The peculiarities of use and consequences of the establishment of certain protection means are indicated. A series of mathematical simulations was carried out, resulting in the level of overvoltages using the means and devices of lightning protection and their absence.

Keywords
