description: Based on the results of the final qualifying work, the electrical part of a built-in 10/0.4 kV transformer substation was designed in the Vasileostrovsky district of St. Petersburg. During the work, the electrical loads of the substation were calculated, a block diagram of the substation was drawn up, and the main electrical equipment and cable lines were selected, taking into account the necessary requirements for the reliability of power supply to receivers. The work carried out a calculation of a three-phase short circuit on the buses of the main distribution board of the designed substation and outgoing connections. Based on the calculated currents and short-circuit currents, the circuit breakers of the main distribution board were selected and the settings for the releases were selected. The choice was made taking into account the necessary reliability requirements. The developed substation is capable of reliably supplying consumers with electricity, power equipment can operate in nominal mode for a long time, and switching devices can reliably protect the substation and consumers from emergency conditions.
