Soilresistivityis a measure of how much the soil resists the flow of electricity. It is a critical factor in design of systems that rely on passing current through the Earth's surface. An understanding of the soil resistivity and how it varies with depth in the soil is necessary to design the grounding system in anelectrical substation, or for lightning conductors. It is needed for design ofgrounding(earthing) electrodes for substations andHigh-voltage direct currenttransmission systems. It can also be a useful measure inagricultureas a proxy measurement for moisture content.+ Read More
