Soil Resistivity and Grounding Electrode Design Explained
Grasping soil resistivity is critically essential for safe grounding electrode planning. Soil resistivity, usually measured in ohm-meters (Ω·m), represents the capacity of the earth to oppose the movement of power charge. Lower readings indicate a higher ability to conduct electricity, reducing grounding opposition. Grounding electrode selection must consider both the resistivity of the local soil and the desired grounding resistance. Various techniques, like using multiple terminals or enhancing ground conductivity with chemical treatments, can be utilized to achieve acceptable grounding performance.
