Description

Ground resistance detection device Technical Field The utility model relates to the technical field of detection devices, in particular to a ground resistance detection device. Background Ground resistance is a key parameter in measuring the effectiveness of grounding an electrical device or system. It represents the amount of resistance encountered when current flows from the ground engaging means to ground. The ideal ground resistance should be as low as possible to ensure that in the event of an electrical fault (e.g. a short circuit) the current can be quickly and safely conducted into the ground through the ground system, thereby protecting personnel and equipment safety, the ground resistance being applied to communication base stations, wind power plants, solar photovoltaic arrays, substations, mining etc. At present, the existing grounding resistor cannot be located in a place with gentle topography, but the grounding resistor can be detected only in a horizontal position when being detected, and if the grounding resistor is located in an inclined position in the detection process, the detection result of the detector is also deviated.
