description: This paper presents a simplified approach to the design of relay protection of a node substation. The calculation of short-circuit currents at four points is performed manually in relative units. An approach to checking switching devices, current-carrying parts and measuring current and voltage transformers under conditions of long-term operation in normal modes and short circuits has been studied. The protection kits were formed in accordance with the standards of the Federal Grid Company (FGC) and the rules for the installation of electrical installations (PUE). The protection of the power autotransformer is considered in the most detail. The terminal BE 2607 542543 of NPP EKRA LLC was chosen as the terminal of the main protection of the autotransformer, after.
