Maintenance of Earthing Systems
-
Regular Inspections
- Visual Checks: Inspect for signs of corrosion, physical damage, and loose connections.
- Grounding Pits: Inspect and clean grounding pits to ensure good contact and prevent contamination.
-
Testing and Monitoring
- Resistance Measurements: Conduct periodic earth resistance tests to detect changes in the grounding system’s performance.
- Thermal Imaging: Use thermal imaging to detect hotspots and potential issues in the grounding grid.
-
Record Keeping
- Documentation: Maintain detailed records of the earthing system’s design, installation, and maintenance activities.
- Compliance: Ensure compliance with relevant standards and regulations.
