Ensuring the reliability of energy systems through the application of a new method for introducing soil-replacement mixtures during the installation of deep grounding devices

This paper discusses a method for using mixtures to optimize the electrical parameters of grounding devices during the installation of vertical composite ground electrodes. The authors propose a design for the coupling and tip for vertical composite ground electrodes. Various techniques for artificially reducing the resistance of the grounding circuit are examined. Results from vertical electrode soundings of the soil at grounding locations are presented. The proposed method allows for the introduction of a mixture simultaneously with the vertical composite grounding electrode, including designs for the coupling, tip, and auxiliary device. Experimental studies of the proposed design have been conducted, and results measuring the resistance to current spread of such grounding devices are presented for both standard and proposed couplings.
