Soil Resistivity and Grounding Electrode Design Explained
Knowing earth resistivity is absolutely vital for safe grounding grid layout. Soil resistivity, typically measured in ohm-meters (Ω·m), represents the capacity of the earth to oppose the passage of electrical flow. Lower values indicate a more ability to carry electricity, reducing grounding impedance. Grounding electrode design must consider both the resistivity of the local ground and the required grounding resistance. Various approaches, like using multiple electrodes or enhancing soil conductivity with material treatments, can be employed to achieve acceptable grounding operation.
