Guide
A field-oriented checklist for oil immersed and dry type transformer inspection, cleaning, temperature, and records.
Quick Answer
Transformer maintenance should track load, temperature, noise, oil condition or coil condition, ventilation, terminals, grounding, protection devices, and routine records.
Confirm load profile, voltage ratio, installation location, grid standards, cooling method, enclosure requirements, accessories, drawings, and test documents before releasing the purchase order.
A strong inquiry includes the single-line diagram, technical specification, transformer quantity, delivery location, preferred standards, and any acceptance testing requirements.
Inspection frequency depends on project rules, environment, and load profile. Industrial sites commonly keep routine visual records and schedule deeper checks during planned shutdowns.
Abnormal noise, high temperature, insulation smell, oil leakage, damaged terminals, protection trips, or repeated overload alarms should be reviewed quickly.
