    Q1: What is ground resistance?
    Ground resistance is the resistance encountered when the current flows from the grounding device to the ground and then flows to another grounding body or spreads to a distant place through the ground. It includes the resistance of the grounding wire and the grounding body itself, the contact resistance between the grounding body and the resistance of the earth, and the resistance of the earth between the two grounding bodies or the earth resistance from the grounding body to infinity. sisco digital earth resistance tester is specially designed for measuring ground resistance, which can prevent ground faults.

    Q2: What is an earth resistance tester?
    A2: The earth resistance tester is a resistance measuring device, which is used to measure the grounding resistance and the resistance value of low-resistance conductors of various equipment in departments such as electric power, post and telecommunications, railways, communications, and mines. The resistance tester also measures soil resistivity and ground voltage.

    Q3: What is the earth resistance tester used for?
    A3: The ground resistance tester can accurately measure the grounding impedance, grounding resistance and grounding reactance of large grounding grids.

    • It accurately measures the surface potential gradient in the large-scale grounding grid area.
    • Earth resistance tester can measure the contact potential difference, contact voltage, step potential difference and step voltage of large grounding grids.
    • Measure the transfer potential of large-scale grounding grids and soil resistivity accurately.
    • Digital earth resistance tester is used to measure the on-resistance of the grounding down-conductor.

    Tips: What is soil resistivity?

    The soil resistivity tester is used to measure the resistivity of the soil. What is the resistivity of the soil?

    Soil resistivity is the average value of soil resistance per unit length. Soil resistivity is a commonly used parameter in the calculation of grounding engineering, which directly affects the size of the grounding resistance of the grounding device, the ground potential distribution of the ground grid, the contact voltage and the step voltage. Soil resistivity is an important factor in determining the resistance of the grounding body. In order to reasonably design the grounding device, the soil resistivity must be measured in order to use the measured resistivity as the calculation parameter of the grounding resistance. One of the methods of measuring soil resistivity is to measure the grounding resistance of the grounding body. After measuring the grounding resistance of the grounding body, the soil resistivity is calculated according to the formula. At present, the soil resistivity tester is one of the most effective equipments for testing resistivity.
