description: In this paper, the reconstruction of a transformer substation is considered. The essence of the reconstruction is an increase in transformer capacity, as well as the replacement of obsolete equipment with more modern and meeting technical requirements. An analysis was made of the technical specifications of PJSC Lenenergo, based on which a transformer of greater power was selected. Also, during the work, calculations were made of switching devices, according to the results of which the corresponding equipment was selected that meets the conditions of the rated current of the release. The calculation of short-circuit currents was carried out to further determine the elements of relay protection. The grounding circuit of the transformer substation was calculated to determine whether the condition required by the regulatory document of the EMP is fulfilled. Lightning protection measures performed during the reconstruction of a transformer substation are described. All calculation data were tabulated. A list of measures for the safe technical operation of electrical installations, as well as the commissioning of electrical installations. At the end of the work, a conclusion was made.
