Soil resistivity test standard
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 finding the best location of a transmitter working on low frequiencies (VLF, LF, MF and lower shortwave) as such radio stations usually use ground as counterpole. An understanding of the soil resistivity and how it varies with depth in the soil is necessary to desig… WebNov 1, 2024 · Standard Test Method for Measurement of Soil Resistivity Using the Wenner Four-Electrode Method 1.1 This test method covers the equipment and procedures for the …

WebOne of our Principal Engineers completed a PhD in soil resistivity testing and analysis before joining ERM, including the development of the recommended range of Wenner spacings that are used in the British Standard and throughout the industry today. They subsequently contributed to the testing section in BS EN 50522. WebPrior to further investigation, soil samples were air dried for two weeks and all the tests were done in accordance with the British Standard Code of Practice (BS1377: (British Standard, Citation 1990)). The soil samples were run through a test sieve of No. 40 (425 m) in order to conduct the Atterberg limit tests (liquid limit, plastic limit ...
