A TECHNIQUE OF MEASURING OF RESISTANCE OF A GROUNDING DEVICE

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...
