description: In this thesis was determined technical solutions to connecting an additional load of NPO "Special Materials" at: Saint-Petersburg, st. Neftyanaya doroga h.5 letter.Ð. To connect additional load, namely, a mechanical assembly workshop with a total installed active power of electricity consumers 230,59 kW, a new power supply scheme from power grid of PJSC Â«LenenergoÂ» with a capacity of 750 kW and a voltage of 0,4 kV. In the thesis the following was done: â calculation of electrical loads for the production complex of NPO "Special Materials" was carried out, taking into account the connection of new consumers of electrical energy; â equipment selection of 6/0,4 kV substation, namely transformers 6/0,4 kV, equipment of switchgears 6 and 0,4 kV; â determined number and cross-section of 6 and 0,4 kV feeders; â confirmed requirements of equipment and feeders by calculations of short-circuit currents; â calculation grounding loop of 6/0,4 kV substation; â solutions of protection the environment during constructing 6/0,4 kV substation; â technical and organizational solutions to safe constructing 6/0,4 kV substation and its further safe operation (safety of people).
