Transformer Changeout Checklist

by Joe Wilson, from the Community

30+

This transformer changeout checklist helps utility and electrical maintenance crews document safe replacement of distribution transformers. Record service and work order numbers, capture nameplate photos, and log manufacturer, KVA rating, voltage, impedance, and serial numbers for both old and new units. Track meters served and obtain signatures to verify work. Use this form to standardize changeouts, maintain asset records, and support safety and compliance across power distribution operations.

Underground Electrical Inspection Checklist
This underground electrical inspection checklist helps engineers and field crews assess underground distribution assets. Record support structure numbers and equipment types, document transformer size and capture nameplate and interior photos, verify primary and secondary wiring, check wire labeling and sizes, and log pedestal presence, IDs, and condition. Use it to determine if components require replacement and to standardize data collection for maintenance and safety compliance.

High Voltage Transformer Inspection Checklist V2
This high voltage transformer inspection checklist helps utilities and electrical maintenance teams assess transformer condition and site safety. It covers access, enclosure integrity, fencing, signage, housekeeping, and base condition; checks for partial discharge and thermal anomalies; records oil level, leaks, and temperature; verifies silica gel condition; captures earth bank test results; and documents LV frame details including isolation method and securing. The template prompts comprehensive photo evidence of the transformer nameplate, interior and exterior condition, and surrounding area to support compliance and maintenance planning.

High Voltage Network Inspection - Transformer
This template helps teams inspect high voltage transformers across substations and networks. It guides users to record transformer details, access and enclosure condition, signage, cleanliness, base integrity, and grounding. Inspectors can capture oil level and temperature, check silica gel condition, look for leaks and partial discharge, review thermal imaging results, and document earth bank test results. It also covers LV frame presence and isolation method, and prompts for comprehensive photos including the transformer nameplate and site surroundings.

Instrument Transformer Test Record
Use this instrument transformer test record to capture device details, visual and functional checks, insulation resistance results (kV, duration, DAR, PI), and ratio test measurements. Log tester make and serial numbers, nameplate data, and drawing references to ensure traceability. Ideal for substation commissioning, maintenance, and compliance in power distribution and industrial facilities. Standardize documentation, improve safety, and keep evidence of test outcomes.
