This annual preventive maintenance template guides visual inspection and testing of high-voltage transformers with oil insulation. It captures site and asset particulars, manufacturer and serial details, thermographic survey findings, visual checks for overheating, corrosion, loose connections, damaged insulators and bushings, tap changer condition, cooling system operation, and warning signage. It includes oil sampling and testing, oil level verification, thermometer and indicator checks, pressure relief and sudden pressure relay checks, seal integrity, and cleanliness before-and-after photos. Technicians can rate condition, document defects, select standardized repair codes, estimate budgets, and set rectification timelines to maintain safe, reliable power distribution.
