This paper, although the 22.9 kV neutral multi-grounding distribution line has a large ground fault current, only a part of the fault current caused by a single line-to-ground fault current into the earth through the earth electrode close to the fault point, and the rest is return to the neural point of the power source through the multi-grounded neutral and earth. As a result of comparative analysis of document and actual measurement cases for the current split rate of the 22.9 kV multi-grounding distribution line, it was confirmed that there are many differences from the split rate generally applied in the substation grounding design.
