摘要

The measurements performed at different substations showed that the grounding resistance of small concrete foundations is comparable with the resistance of the ground rods. Hence, these foundations could sufficiently influence the overall grounding resistance of the substation. This paper presents a simple method for calculating grounding resistance of such a foundation. Calculation is based on the size of the foundation and the value of soil resistivity in the installation's location. It is not necessary to know the exact size and location of the reinforcement in the foundation and resistivity of concrete. The proposed method is confirmed by laboratory tests and field measurements.
