PROTECTIVE GROUNDING OF ELECTRICAL INSTALLATIONS Russian patent published in 2021 - IPC H01R4/66 H02H9/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to protective grounding of electrical installations. The technical result is achieved by the fact that the protective grounding of electrical installations consists of one or more electrically connected ground wires covered with electronegative metals or their alloys and located in the ground, the grounding bus for the electrical connection of ground wires to the electrical installation, additionally contains a polarized screen installed in the ground near the grounding electrodes, as well as a potential displacement station connected by the positive pole to the grounding bus, and the negative pole to the polarized screen.

EFFECT: ensuring a reduction in electricity consumption by cathodic protection stations, increasing the service life of anode ground wires, as well as providing the necessary reserve stock of cathodic protection converters in current and power
