Earthing design



In order to conduct earthing design, we need to know…
·the current earth resistivity,
·the site dimensions (from diagrams, etc.), and
·the existing earth resistance.

Works example
Earth resistivity measurement: checking the surrounding environment, such as understanding the inherent resistance value of the soil, and determining the material and equipment delivery route.
Produce ρ−a curve: calculate average earth resistivity and understand electrical tendencies of the soil on site.
Propose design after consideration of prevailing conditions (site dimensions, required earth resistance, physical limitations, etc.)
