- Abstract
In the presented article, by the method of planning an experiment, an analysis of the parameters that affect the stability of high-voltage overhead power lines to the effects of atmospheric overvoltages was carried out. The parameters that have a greater impact on the reliability of high-voltage overhead power lines from lightning surges are determined. Partially changing the design of the ground wire, a new effective method was proposed to increase the protection zone by winding longitudinal metal rods in the shape of the letter "V" on its surface. The possibility of increasing the lightning protection zone by placing these simple elements on the surface of the ground wire is shown, in addition, the possibility of further reducing the probability of the passage of the lightning channel bypassing the ground wire and directly falling into the conductor due to the increase in the inhomogeneity of the electric field between the ground wire and the lightning rod.
