How To Check Earth Resistance Value at Bret Stephen blog

How To Check Earth Resistance Value. Using ohm’s law (v = ir), you get an accurate measurement of the resistance of the earth electrode. A practical earth electrode that provides a low ground resistance is not always easy to obtain. But from experience gained by others you can learn how to set up a reliable system and how to check the resistance value with reasonable accuracy. Earth resistance is an important parameter for designing and maintaining earthing systems. Determining effectiveness of “ground” grids and connections that are used with. Connect the ground tester as shown in the picture. Earth resistance is measured in two ways for two important fields of use: It involves taking a number of resistance measurements at various earth system to voltage electrode separations and then plotting a curve of the resistance variation between the earth and the current. Recommended grounding resistance per ieee and nfpa standards is typically < 5 ohms, also applicable to telecommunications. Touch potential is determined by first measuring the resistance to earth of the object in question, using techniques similar to those used to measure the resistance of an earth electrode. It depends on various factors such as soil resistivity, electrode size, shape, depth, material, etc.
