Soil Resistivity and Grounding Electrode Design Explained
Knowing ground impedance is completely vital for effective grounding grid planning. Soil resistivity, usually measured in ohm-meters (Ω·m), represents the tendency of the earth to resist the flow of electrical flow. Lower readings indicate a more ability to transmit 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 electrodes or enhancing ground conductivity with additive treatments, can be employed to achieve acceptable grounding operation.
