Background

The ground resistance is a resistance encountered by a current flowing from a ground device into the ground and then flowing through the ground to another ground body or spreading to a distant place. The value of the grounding resistance represents the degree of good contact of the electrical device with "ground" and reflects the size of the grounding grid.

The grounding resistance meter mainly comprises a hand-operated generator, a current transformer, a potentiometer and a galvanometer. The accuracy of the test value of the grounding resistance is one of the important factors for judging whether the grounding is good or not. Once the test value is inaccurate, manpower and material resources are not wasted (the measured value is larger), and potential safety hazards are not brought to the grounding equipment (the measured value is smaller). The traditional grounding resistance detection mostly depends on the direct detection of an electric pen, but due to the long-term use of the grounding resistance, related impurities are often attached to the surface of the resistance, and the measurement is inaccurate.
