Padmount Transformer External Inspection

The padmount transformer check is oil stains, rust, the lock, the pad, and a gauge you can read with the primary compartment shut. The technician writes the as-found reading and compares it with the last one on the asset. This work order does not authorize opening a primary enclosure. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. From outside the locked cabinet, look for oil stains, rust, damage and a settled pad
  2. Read the gauge you can see without opening the primary compartment
  3. Confirm the lock is the site's lock and the pad is not undermined
  4. This work order does not authorize opening a primary enclosure
  5. An oil stain or a broken lock is a finding for the switching authority

Why This PM Exists

The padmount transformer check is oil stains, rust, the lock, the pad, and a gauge you can read with the primary compartment shut. The technician writes the as-found reading and compares it with the last one on the asset. This work order does not authorize opening a primary enclosure.

What Skipping It Looks Like

A broken lock gets replaced with whatever is on the truck, and the oil stain never gets written for the switching authority. The round still closes, the number never lands on the asset, and the next person inherits a guess. This work order does not authorize opening a primary enclosure.

Setting the interval

Every ninety days, from outside the locked cabinet. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.
