Analysis on structural parameters and electrical performance of dc deep well grounding electrode

The Journal of Engineering, 2019
Deep well-grounding electrodes (DWGE) have advantage of smaller occupied area, and the number of sub-ground electrodes is less than that of the vertical grounding electrodes, thus has a good development prospects.
