Means and devices of lightning protection of overhead transmission lines of voltage class 110–750 kV
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.
