Proper grounding is essential for ensuring the safety of both people and equipment. It plays a critical role in preventing electrical hazards and protecting sensitive electronics from damage. Grounding systems must be carefully designed and maintained to ensure their effectiveness. In practice, regular inspections and maintenance are necessary for all types of grounding devices. Temporary checks should also be conducted based on specific conditions or environmental changes. The standard maintenance schedule for grounding systems typically includes an annual measurement of the grounding resistance for substation grounding grids and equipment grounding systems within factories. This helps verify that the system meets required standards and allows for analysis of any changes over time. For other grounding systems, measurements are generally carried out every two years. However, the frequency may increase depending on factors such as the size of the grounding system, its importance in the electrical network, and seasonal variations. Key inspection points include: 1) Checking if the grounding wire is broken, damaged, or severely corroded. 2) Ensuring that the connection between the grounding branch and the main trunk is secure. 3) Looking for signs of soil disturbance around the grounding point due to external forces. 4) Verifying that the grounding wire, grounding body, and connections remain intact. 5) Inspecting all bolted connections for looseness and tightening them if needed. 6) Excavating the area around the grounding electrode to check for corrosion on the underground section up to 0.5 meters deep. If significant corrosion is found, immediate replacement is necessary. 7) Confirming that the grounding wire’s clamps and jumper wires are in good condition. 8) Checking for flaking paint on fixed grounding lines and repainting if necessary to maintain clear markings. 9) Examining whether the grounding body has become too close to the surface due to water erosion or other factors. If so, repairs should be made promptly. 10) Keeping detailed records of all maintenance, inspections, and measurements performed on the grounding system. Regular attention to these aspects ensures the long-term reliability and safety of your grounding system, reducing the risk of electrical failures and potential harm.
