Package List
Q1: What is ground resistance?
A1: 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 the three-wire method of a ground resistance tester?
Find two independent grounding bodies RB and RC near the grounding body RA to be tested, and measure RA and RB respectively. The values of RA and RC, RB and RC are calculated to obtain the value of RA. This is the three-wire method of the ground resistance tester.
