Earth Resistivity Test
The Earth Resistivity Test is conducted to determine the resistivity of soil which is essential for designing grounding systems (earthing), assessing corrosion risk, and subsurface characterization. The test is based on Ohm’s Law, measuring the potential difference created when a known current is passed through the soil. This test provides essential data for designing earthing systems, grounding grids, and lightning protection systems. The test is simple, non-destructive, and provides reliable data for power substations, industrial installations, and infrastructure projects.
Purpose of Earth Resistivity Test
- To determine soil resistivity for the design of effective earthing systems.
- To prevent electrical hazards by ensuring low-resistance grounding.
- To assess the suitability of soil for electrical, industrial, and infrastructure applications.
