Soil Resistivity and Grounding Electrode Design Explained
Understanding earth resistivity is completely essential for safe earthing grid layout. Soil resistivity, typically measured in ohm-meters (Ω·m), represents the capacity of the ground to oppose the passage of power current. Lower levels indicate a better ability to conduct power, reducing grounding resistance. Grounding electrode design must consider both the resistivity of the surrounding ground and the desired grounding opposition. Various techniques, like using multiple terminals or enhancing soil conductivity with material processes, can be employed to achieve acceptable grounding operation.
