3732: Guidelines for Grounding Stations and Lines in High Resistivity Earth Conditions
Low ground electrode resistance effectively dissipates fault currents into the earth. This reduces the ground potential rise (GPR) and, consequently, the touch and step potentials that a person may be subject to during normal and fault conditions. The resistance value depends primarily on the soil resistivity and the grounding grid’s area and depth. In practice, these parameters often have less than ideal values. For example, the grounding grid’s area may be limited, natural soil conditions may
