ELECTRICAL DISTRIBUTION NETWORK Russian patent published in 2025 - IPC H02J3/00 H02H5/10 

FIELD: electric power industry.

SUBSTANCE: invention relates to electric power engineering and can be used for power supply of groups of single- and three-phase consumers. To ensure electrical safety for consumers in a distribution electric network, which includes a three-wire branched line (1) connecting the supply and distribution elements, according to the invention, and distribution elements used are three-phase supply (2) and distribution (3) transformer substations, and group of three-phase consumers (4) with protective grounding (5), connected to three-wire branched line 1, and three groups of single-phase consumers (6). Three-phase supply transformer substation (2) has working grounding (7) of zero point of secondary winding of substation (2). At that, transformer windings of three-phase distribution substation (3) are connected according to star-star scheme, and each group of single-phase consumers (6) is connected by two conductors (8) to phases of three-phase distribution transformer substation (3), and the third conductor is connected to protective grounding (10) of the housing of the three-phase distribution transformer substation (3).

EFFECT: provision of electric safety of operation of electric distribution network.
