description: The given work is devoted to the calculation of the protection of the transformer, which is part of the 5AN circuit of the substation switchgear. The calculation is performed for microprocessor protection cabinets for transformers and autotransformers manufactured by NPP EKRA SHE2607 041 LLC. The research set the following goals: Study of methods for selecting the main substation components. Calculation of shortâcircuit currents in two ways - analytical and using the RastWin software package. Selection of sets of basic and backup protections.Calculation of settings according to the manufacturer's manuals, as well as using the FSK EES methodological guide.Â Calculations were carried out. Decisions of the choice of the composition of the relay protection were made according to the results. Verification of calculations, as well as additional calculations were carried out using Â«RastrwinÂ» software, equipped with databases of necessary electrical machines and connections, as well as methods for calculating operating modes.Â The results of this work can be used to calculate the relay protection of substation transformers with the switchgear 5AN scheme at a voltage from 35 kV to 220 kV.
