What is Soil Resistivity?
Soil resistivity is a measure of how much the soil resists the flow of electricity. Soil Resistivity Testing is determining that measure. Therefore, is a critical factor in the 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 electrical earthing systems. In an electrical substation, or for lightning conductors. Also for the design of earthing electrodes for substations and high-voltage direct current transmission systems needs this measurement. Because most substations, use the earth to conduct all or, a significant portion of fault current when there are earthing faults on the system.[Read more…] about Importance of Soil Resistivity Testing for Electrical Earthing Design
