3731: Guidelines for Reducing Ground Resistance for Different Electrode Designs
Low ground electrode resistance effectively dissipates fault current 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 ground grid’s area and depth. In practice, these parameters often have less than ideal values. For example, the size of the area may be limited, natural soil conditions may hav
