WebJul 17, 2024 · Soil Resistivity: 15 Things (2024) You Need To Know. Soil electrical resistivity (or ER) is a significant indicator that indirectly determines both soil physical and chemical properties, including moisture, salinity, porosity, organic matter level, bulk density, and soil texture. As such, it is an important part of determining soil quality. WebThe maximum value of a single line to earth fault current is considered as 80 kA. Based on soil resistivity testing at various locations, average soil resistivity 12.46 ohm-m shall be considered for earthing system calculation which is done by wenner’s method.. Electric Resistivity in ohm-m = 2πRS
