The impedance characteristics and equipotential pattern in ground surface of horizontal and grid configuration of grounding systems which are injected by frequency variable alternating currents?
In this paper is reported the result of laboratory experiments with the simulation of grounding systems in scaling down. The measurements in this experiments use the fall of potential method. Special grounding systems for body or casing of equipments, the impedance is small and this value can be obtained by buried the grounding electrode so deeply read more..
