description: The final qualifying work consists of an introduction, seven chapters, a conclusion and a list of sources used. The first chapter provides a brief description of consumers and initial data, as well as identifies the main objectives of the thesis. In the second chapter, the calculation of electrical loads according to tabular specific indicators is considered in detail. In the third chapter, the choice of the number, power and type of power oil transformers is made. In the fourth chapter, the selection of the cross-sections of the power cables was made, and the cable lines were checked for permissible relative voltage losses. The fifth chapter describes the calculation of short-circuit currents based on the most severe conditions of their flow, namely: on the buses of high and low voltage switchgear. The sixth and seventh chapters are devoted to the selection of the main electrical equipment in the transformer substation and the main switchboards of electrical consumers. In the conclusion, the results of the work are summed up and the main conclusions are drawn.
