WebGround resistance is the resistance between a grounding electrode and the earth. It cannot be measured without inserting the electrode into the ground. Since earth has comparatively low resistivity, a voltage drop occurs near the electrode from which the current used to make the measurement flows. Consequently, in order to accurately measure ... Webinterest in earth testing. Earth resistivity measurements can be used conveniently for geophysical prospecting — to locate ore bodies, clays, and water-bearing gravel beneath the earth’s surface. The measurement can also be used to determine depth to bed rock and thickness of glacial drift.
WebThe clamp-on methodology is based on Ohm’s Law (R=V/I). A known voltage is applied to a complete circuit and the resulting current flow is measured. The resistance of the circuit can then be calculated. The clamp-on ground tester applies the signal and measures the current without a direct electrical connection. WebTo perform the test, follow the procedure as: Firstly, place a clamp meter near the earth electrode. This eliminates any parallel resistance effects. Secondly, place outer and inner …
