How to determine the resistance of earth electrode?

WebThe ground electrode is surrounded by earth which conceptually is made up of concentric shells all having the same thickness. Those shells closest to the ground electrode have the smallest amount of area resulting in the greatest degree of resistance. Each subsequent shell incorporates a greater area resulting in lower resistance. WebFigure 1. Measuring circuit for Fall of Potential test. When wired as shown, one of the Fluke 162x series Earth Ground Testers forces a known current between the outer stake and the Earth electrode, creating a voltage gradient in the soil. The tester then measures the voltage drop between the inner stake and the earth electrode. irfc grand est
