Electrical Resistivity Survey

Soil resistivity testing measures the capacity of the ground to pass an electrical current. This property utilizes the electrical power industry for assessing the design requirements of earthing systems. STS provides soil resistivity testing services to assist in the design and installation of power generation plant, substations and engineering infrastructure.

The correct measurement of soil resistivity is particularly important in high resistivity ground. Specifically, where electrical currents do not dissipate readily. In such ground conditions achieving a good earth can be problematic. Information on ground resistivity is required in much greater depths for the successful installation of an earthing system.
