WebMay 22, 2024 · One of these alternative methods is variation of depth, or the three-point method. Here, ground resistance measurements are repeated in correlation with incremental increases in ground rod depth. This technique forces more test current through deep soil, and changes in resistivity can be noted at each depth. The most important precautions to be taken before starting the measurement is Step1:Disconnect the electrode from the load so that we can get the actual value of the earth.
