description: In this paper, a study of measures to improve the lightning protection of 220 kV overhead line "Zhaksy-Perekatnaya" without a lightning cable is carried out when using 220 kV OPN. In the course of the work, the main parameters of lightning, methods of protection against them and the consequences of lightning strikes on the line were considered. To conduct experiments in the EMTP software package, a model of an overhead line, a model of a support, linear isolation and an overvoltage limiter were modeled. A current source with an oblique pulse was used to simulate a lightning strike. The analysis of lightning protection of 220 kV "Zhaksy-Perekatnaya" overhead line with nonlinear surge limiters (OPN) and without with different grounding resistances of supports was carried out. The energies released on protective devices when lightning strikes the support and the phase wire were also calculated. The analysis of the impulse strength of the line, performed using a simulated model, showed the effectiveness of using the OPN. According to the results of the study, it was found that such factors as: the grounding resistance of the support, the pulse duration and the location of the lightning strike have a strong influence on the lightning resistance of the overhead line.
