description: This work includes an analysis of the reliability of substations against incoming waves from incoming lines in the presence of protective devices, such as surge arresters, as well as the use of a lightning protection wire to improve the reliability of lightning protection. A comparative characteristic of the obtained data with the permissible indicators, regulated by the PUE in terms of the reliability of the electrical equipment of the substation, is made. The work is based on the assessment of lightning protection for such voltage classes as 110,220 kV. Tasks solved in the course of the study: 1. Study of the reliability of electrical equipment depending on the distance to the protected device. 2. The influence of the presence of a lightning wire on the reliability of the lightning protection of the substation. 3. Analysis of the use of the installation of protective devices with 3 or more outgoing overhead lines. 4. Development of conditions for increasing the reliability of the number of years of trouble-free operation of equipment As a result of the work, statistical calculation results were obtained and a comparative characteristic of the number of years of trouble-free operation of equipment when using a lightning wire and when dismantling it was given. Based on the studies carried out, it was concluded that it is advisable to use a ground wire at all sections of the substation.
