description: In this paper, the lightning protection of substations from incoming waves from incoming lines is investigated from the point of view of installing such protective devices as nonlinear surge arresters (OPN). The results of the study are compared with the recommendations of the PUE, which are mainly focused on the use of outdated and outdated valve arresters (RV).Â The study of lightning protection of substations was carried out for voltage classes 110 and 220 kV on the example of typical schemes of open switchgear (ORU): "Transformer-line block" (110 and 220 kV), "Bridge" (110 and 220 kV). All calculations were carried out using the Minsk software package. The reliability indicators of lightning protection of substations are determined depending on various factors, namely: the distance between the protected object and the protective apparatus, the resistance of the grounding devices of the supports on the approach to the substation, the presence or absence of a protected cable approach and the type of lightning protection scheme of the substation.Â Â Â Â Â
