An Original Setup to Measure Grounding Resistances Using Auxiliary Circuits Buried Vertically in the Ground

Considering that grounding systems must be evaluated periodically by measuring their grounding resistance and that many of these systems are found in places whose neighborhood is congested, making it difficult or even impossible to use measuring leads in the external environment, a measurement innovative methodology is proposed to mitigate this problem. This paper presents a preliminary analysis of the feasibility of measuring grounding resistances using the auxiliary circuits buried vertically in the ground. Measurements on a reduced model using the auxiliary circuits vertically buried in the ground and a theoretical analysis of the problem are presented.
