Earth potential rise
WebEarth Potential Rise (EPR) What happens when current flows into the ground? How and where do touch voltages appear? How do I determine the optimum model? When should I use multi-layer soil models? The Earth Fault Circuit Where does earth fault current actually flow? Are interconnections to other earthing systems helpful or hazardous?
