Package List
Tip: What is earth resistance?
Earth 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.
