How to Measure Soil Resistivity: Detailed Process Explained
Measuring soil resistivity is essential before designing a grounded earthing system for a substation. Because this measurement determines how well the ground can dissipate fault currents. If the soil resistivity is high, the grounding system needs some changes. It requires denser earthing mesh and more conductive electrodes. A well-designed earthing system prevents intolerable voltage buildup. … Read more
