WebJun 17, 2010 · Practical test methods and techniques are presented for measuring the electrical characteristics of grounding systems. Topics addressed include safety considerations, measuring earth resistivity, measuring the power system frequency resistance or impedance of the ground system to remote earth, measuring the transient … 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 ...

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. WebAug 20, 2024 · Figure 2. A plot of per-unit resistance of a grounding electrode and test probe. Table 1 and Figure 2 show an outcome when the layers of electrodes 1 and 2 interfere (overlap) each other. As we progress from electrode 1 in a straight line toward electrode 2, the ground resistance rises quickly in the first few layers and then flattens out. csc security controls
