Earth/Ground System Test Services
Grounding is to eliminate dangerous voltages (like Step Contact Voltages) completely. In order to secure the continuity of the electrical systems and the human life, the electrical parts are insulated. It is inevitable that an error occurs in the form of deterioration or puncture due to various reasons in the insulation against earth. In such an error, the measurement of grounding resistance must be carried out periodically to secure human life. Our services about Earth System Tests;
- Specific Earth Resistance Measurement
- Plant Earth Resistance Measurement
- Equipment Earth Resistance Measurement
- Lightning Rode Earth Resistance Measurement
- Earth Resistance Measurement with SELVAZ (Selected Voltage-Ampere-Impedance) Method
- Step Voltage Measurement
