Soil resistivity and earth conductivity are two basic parameters often used in power system design, both of which typically need to be obtained by field testing. The soil resistivity and the earth conductivity are tested by generally adopting a direct current resistivity method, and the common device forms are Schlenbel and Wennan symmetric quadrupoles and the like. The soil resistivity is a commonly used parameter in the calculation of grounding engineering, and directly influences the size of the grounding resistance of a grounding device, the ground potential distribution of a ground grid, the contact voltage and the step voltage. The soil resistivity is an important factor for determining the resistance of the grounding body, and in order to reasonably design a grounding device, the soil resistivity needs to be actually measured so as to use the actually measured resistivity as a calculation parameter of the grounding resistance. One method for measuring the soil resistivity is to measure the grounding resistance of a grounding body, and then calculate the soil resistivity according to a formula after measuring the grounding resistance of the grounding body. The above method has a disadvantage that a large error may be caused due to the influence of the ground resistance, and if the ground structure is not uniform, the calculated soil resistivity also varies with the size and the burying manner of the ground body.
