Description
technical field [0001] The invention relates to a power system measuring device, in particular to a high-precision and low-power-consumption grounding resistance testing device. Background technique [0002] The grounding resistance tester is a common instrument for testing and measuring grounding resistance, and it is also an indispensable tool for electrical safety inspection and completion acceptance of grounding projects. Since the ground resistance tester is mostly used in the field, the distance between each measurement point is relatively long, and the measurement personnel need to carry the instrument to run between each measurement point. The field is complicated and not suitable for vehicles such as cars; Manually and quickly shaking the generator shaft of the ground resistance tester consumes a lot of physical strength and is inconvenient to use. Contents of the invention [0003] In order to solve the above problems, the present invention provides a high-prec...
