description: This work is devoted to the design of a 10 / 0.4 kV transformer substation. The substation is made in a complete kiosk version of the KTPn-1000/10 / 0.4 series, which includes switchgears of two voltages 10, 0.4 kV, and a section for installing a 10 / 0.4 kV transformer. The calculation and selection of a power transformer of the TMG21 630/10 / 0.4 U1 brand has been performed. Inside each switchgear, two switching and protective devices provide emergency shutdown in emergencies. A 10 kV switchgear is equipped with a VNA / TE-P (p) -10 / 630-ZnP autogas load switch with the use of PKT-10 series fuses. A 0.4 kV VA-99 circuit breaker rated 1000 A protects the transformer, and VA44 series circuit breakers of the corresponding rating protect outgoing overhead power lines. In the course of the work, the code-dependent parameters of the SIP-2 brand wires, with a cross section from 50 to 95 mm2, on the 0.4 kV overhead lines leaving the substation were also selected. The short-circuit currents were calculated, on the basis of which the permissible values of the protection devices were selected. In the final chapter, the issue of grounding the designed electrical installations to meet the requirements of standards is considered.
