Earth Resistance Testing


resistivitySoil resistivity is a measure of how much the soil resists the flow of electricity. It is a critical factor in design of systems that rely on passing current through the Earth’s surface. An understanding of the soil resistivity and how it varies with depth in the soil is necessary to design the grounding system in an electrical substation, or for lightning conductors. It is needed for design of grounding (earthing) electrodes for substations and High-voltage direct current transmission systems.

CPTWest can carry out earth resistance testing, using the Wenner Array method, or alternately, the client site representative can use our equipment which will be carried on board our CPT rig at all times.
