HV Earthing Preventive Maintenance Checklist
by Patrick Vandeleur, from the Community
This HV earthing preventive maintenance checklist supports annual service reporting and visual inspections for high-voltage earthing systems. Record facilities and assets, capture equipment details, rate condition from P6 to P1, and confirm continuity under 1.0 Ohm using a calibrated low-ohm meter per AS/NZS 3760. Log test results, add photos before and after cleaning, and summarize overall condition. Use structured repair codes to describe defects, plan rectification, estimate budgets, and set due dates. Ideal for hospitals, airports, utilities, schools, and commercial sites.
