What is a good ground resistance value? - Quora
WebApr 18, 2024 · From the standards for grounding by the International Electrotechnical Commission (IEC) 60364, the Electrical Equipment Technology Standards (EETS) are set up for the grounding resistance to be less than or equal to 10 for high voltage (above 750 V DC) and extra high voltage (above 7000 V) systems. WebDec 30, 1999 · The earth's ground resistance as determined by the fall of potential method is the resistance of the earth between the grounding electrode and voltage test stake. It is not the impedance of the ground fault return path. The earth resistance value is irrelevant as it relates to fault current flow and touch potential. change chocolatey install directory
