The influence of fault current & soil resistivity on the substation grounding grid behaviour

The effects of fault current and soil resistivity on grounding performance are shown in this work. The fault current and soil characteristics are modified from the real values in a case study based on an actual main intake substation grounding grid utilizing CDEGS simulation software. Grounding grid...
