description: This work is devoted to the modernization of one of the main substations supplying the Kurortny district of the city of St. Petersburg, due to the lack of free transformer capacity for the technological connection of new consumers, as well as changing the switchgear circuit to remove equipment for repairs without removing the operating currents. The work was carried out based on the rules for electrical installations, regulatory and technical documentation, as well as organizational standards provided by the branch of PJSC Rosseti Lenenergo âSt. Petersburg High Voltage Networksâ. As a result, new equipment from domestic manufacturers was selected to modernize the switchgear circuit, short-circuit current calculations were carried out, and relay protection and automation were replaced.
