DY1000/DY1100 in the measurement of a grounding system with loop, does not require breaking down the grounding wire, and need no auxiliary electrode. It is safe, fast and simple in use.It can measure out the faults beyond the reach of the traditional methods, and can be applied in the occasions not in the range of the traditional methods. DY1000/DY1100 can measure the integrated value of the grounding body resistance and the grounding lead resistance.
DY1000/DY1100 are equipped with either a long jaw or a short jaw, as indicated in the figure below. A long jaw is particularly suitable for the occasion of grounding with the flat steel.
