Understanding Soil Resistivity & Soil Resistivity Testing Methods

Ian getting ready

Understanding Soil Resistivity is critical to Electrical Earthing System Design. Soil Resistivity Soil resistivity is a measure of how much the soil resists the flow of electricity. So an understanding of the soil resistivity and how it varies with depth in the soil is necessary to design the grounding – earthing system in an electrical […]
