A TECHNIQUE OF MEASURING OF RESISTANCE OF A GROUNDING DEVICE
Electrical Engineering & Electromechanics, 2016 Introduction. Measurement of resistance of the grounding device (GD) by means of a three-electrode system. This requires not only the right choice of installation locations of measuring electrodes, but also the determination of the point of zero potential. Implementation of these requirements quite time-consuming, and in some cases impossible.
