What is the 4-Point Soil Resistivity Test? (Part 2)

E&S Grounding Solutions

In this episode, E&S Grounding Solutions President David Stockin continues a discussion on the Wenner four-point method for testing soil resistivity. Sounding should occur at least to the extent of the sphere of influence, which can be determined from the diagonal length of the grounding system. Selecting the proper intervals of test probe spacing is important to avoid a mathematical headache and obtain more accurate models of the soil resistivity. IEEE Standard 80 suggests taking soundings at a depth of up to three times the extent of the sphere of influence. It is very important to know how to safely handle the high-power equipment used to get the deeper soundings. For a video of this podcast, please visit our YouTube Channel at E&S Grounding Solutions.
