WebOne 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 … Webresistivity of soil are the parameters that involve in determining the corrosivity of the soil. The concentrations of the soil parameters are found to have the following properties: pH (1.76- 5.6), temperature (25-50°C), moisture contents (20 – 40%), and resistivity (<1000 Ω.cm). Corrosivity of the soil samples were evaluated using the
