Tables are provided for Soil Electrical Resistivity values for different Soil Types, Geology, and Surface Layers Materials in Substations.
Soil Resistivity Values for Different Types of Soil
One key determinant of a good earthing installation is the soil resistivity of the soil where the earth electrode is installed. If you are involved in earthing buildings and electrical installations, here is a list of the typical soil resistivity values for different types of soil that you might encounter:

2020年8月28日 · Table 2 exhibits resistivity values for some types of soils and rocks, expressed in common terms and measured by different methods. Observe the full range of values for each type of soil. The actual resistivity can vary within the maximum and minimum values quoted there. Table 2 Resistivity of different soils
Abstract: Soil electrical resistivity is the property of the soil that impedes or resists the flow of electric current through it. It is a function of the soil moisture and the concentrations of the soluble salts present in the soil and is one of the most comprehensive parameters to test soil corrosivity.
Resistivity is basic parameter to measure the conductive property of materials. Resistivity of the soil, which varies with parameters such as moisture content, temperature and depth effected earth resistance value.
