The main content of this work is to develop transformer protection in accordance with the needs of the power plant itself. Problems that were solved during the design: 1) Design of the electrical part of the power plant: selection of power equipment (generators, transformers), distribution cabinet diagrams and basic electrical connection diagrams of the thermal power plant; 2) Calculate the short circuit current and protection settings of the transformer.; 3 )Complete the selection of electrical equipment such as circuit breakers, generator breakers, current transformers, voltage transformers, wires and busbars. During the design, three-phase short circuit currents were calculated, based on which further selection of equipment and current-carrying parts was made for 220 kV switchgear and 6 kV SN switchgear. The parameters of the disconnector ELK - 220 / 3150 UHLI, GIS SPE - 1000, technical characteristics of EGRU NES 7 were used.
