WebSoil Resistivity (:m) Magnitude X0 R0 Fig. 4. Impact of soil resistivity (ˆ) on line parameters. soil resistivity at different depth levels in soil. For example, the soil resistivity of a small section of the ROW for a transmission line is shown in Fig. 6. As can be seen, this data is tagged with GPS coordinates and can be readily used Web325 C1.3 Electrical resistivity of multiphase materials Pure materials are rarely found in the Earth and most rocks are a mixture of two or more phases (solid, liquid or gas). Thus to calculate the overall electrical resistivity of a rock, we must consider the individual resistivities and then compute the overall electrical resistivity.
