Webρ = soil resistivity in Ohm meters (assuming a uniform soil). L = length of electrode buried in soil in meters. A = area in square meters. From the above, if the soil resistivity is known then the theoretical resistance of a single vertically driven earth rod can be approximately calculated using the formula below. Where: Several methods of resistivity measurement are frequently employed: For measurement the user can use Grounding resistance tester . Wenner method [ edit] The Wenner four-pin method, as shown in figure above, is the most commonly used technique for soil resistivity measurements. See more Soil resistivity is a measure of how much the soil resists or conducts electric current. It is a critical factor in design of systems that rely on passing current through the Earth's surface. It is a very important parameter for … See more Because soil quality may vary greatly with depth and over a wide lateral area, estimation of soil resistivity based on soil classification provide only a rough approximation. … See more Soil resistivity is one of the driving factors determining the corrosiveness of soil. The soil corrosiveness is classified based on soil electrical See more Electrical conduction in soil is essentially electrolytic and for this reason the soil resistivity depends on: • moisture content • salt content See more • Wenner, Frank (1916).
