About this file

This document is a detailed maintenance checklist for annual transformer oil pad mounted inspections. The checklist outlines seven specific maintenance tasks, each with an allocated labor time, including: examining the transformer exterior for damage, checking the ground system, recording oil level/pressure/temperature, verifying auxiliary device operation, drawing and testing an oil sample, cleaning the transformer and surrounding area, and completing a maintenance report. The tasks are designed to ensure comprehensive inspection and documentation of transformer condition, with a section for noting any discrepancies that may require follow-on work orders. The checklist also includes a condition index rating system (Green+/Green/Green- to Red+/Red/Red-) and spaces to record start/end times, date, and technician signature.
