Earth Resistance Measurement By Fall Of Potential Method at Hamish Gellatly blog

Earth Resistance Measurement By Fall Of Potential Method. First, the earth electrode of interest must be disconnected from its connection to the site. In order to test the resistance using this method, two test electrodes and an earth resistance tester are required. The measurement of earth resistance is made by the potential fall method. Fall of potential method : Shape and material of earth electrode or electrodes used. The below shows the circuit. The resistance area of the earth electrode is the area of the soil around which a voltage. The method uses three electrodes, among which one electrode is under test and the other two are auxiliary electrodes. Second, the tester is connected to the earth electrode. The basis of this method is ohm’s law. 3.the specific resistance of soil surrounding and in the neighbourhood of electrodes. The fall of potential method accurately tests the resistance of a grounding electrode. Depth in the soil at which the electrodes are hurried. One of these electrodes is used to inject current into the ground and the other (potential electrode) is used to check the voltage. The specific resistance of the soil is not constant but varies with one type of soil to another.
