Soil Resistivity and Grounding Electrode Design Explained
Knowing ground impedance is critically important for proper earthing electrode layout. Soil resistivity, often measured in ohm-meters (Ω·m), represents the ability of the soil to resist the movement of electric flow. Lower readings indicate a better ability to carry current, reducing grounding impedance. Grounding electrode selection must consider both the resistivity of the surrounding soil and the required grounding opposition. Various methods, like using multiple rods or enhancing ground conductivity with chemical processes, can be employed to achieve acceptable grounding functionality.
