description: During the work, the following main tasks were solved: 1) analysis of the current state of the substation, loads, main power equipment; 2) determination of short circuit currents and testing of switches and cable lines; 3) analysis of necessary measures within the framework of technological connection of the consumer; 4) assessment of the influence of the consumerâs motor load and reconstruction measures on the magnitude of short-circuit currents. The power switches were checked for electrodynamic and thermal resistance, and the cable lines were checked for permissible core heating. All substation equipment after reconstruction was tested according to the specified criteria. Based on the results of the final qualifying work, a project was developed for the reconstruction of a 6/0.4 kV distribution transformer point in the Leningrad region.
