  • [Introduction] The current releasing density is one of the key parameters for the performance of DC vertical earthing electrode. [Method] Based on the structure characteristics of vertical DC earthing electrode, study of the influence of sub-electrodes number, sub-electrodes length, sub-electrodes gap distance and electrode well section on the current releasing density and its evenness were carried out. [Result] The study shows that the current releasing density is related to the total length of sub-electrodes, and it is not related to the number of sub-electrodes and the gap distance between them. However, the unevenness of current releasing density is related to the gap distance and the electrode well section. [Conclusion] Optimized vertical electrode structure is presented according to the study results.
