Soil Resistivity and Grounding Electrode Design Explained
Understanding earth conductivity is absolutely vital for safe bonding electrode planning. Soil resistivity, usually measured in ohm-meters (Ω·m), represents the capacity of the earth to resist the movement of power current. Lower levels indicate a better ability to carry current, reducing grounding resistance. Grounding electrode design must consider both the resistivity of the local ground and the needed grounding resistance. Various techniques, like using multiple electrodes or enhancing soil conductivity with chemical processes, can be employed to achieve acceptable grounding operation.
