Liquid-immersed transformers have their core and coils sitting in insulating oil, which insulates them and carries heat away. Tanks and radiators can start leaking oil, most often at connections, headers and individual pipes. Bushings can also leak through a gasket, a soldered or welded seal, or a cracked insulator, and a falling oil level is a warning sign. Spilled oil that reaches land or waterways puts human health, drinking water and natural resources at risk. Oil leaks are serious maintenance and environmental problems, so treat them with care and get them repaired instead of ignoring them. Regular infrared scans and physical inspection of tanks, radiators, pump piping and heat exchangers help find leaks early. In the United States, the EPA Spill Prevention, Control, and Countermeasure rule (40 CFR Part 112) aims to stop facilities from discharging oil into navigable waters and their shorelines.
<!-- review notes
- sentence 6: support check: partial - Passage supports yearly IR scan and physical inspection of radiators and tanks and inspecting pump piping and heat exchangers for leaks, but IR scans are not stated for pump piping or heat exchangers and are not tied to finding leaks early.

Transformer inspection
Periodic IR scans and physical inspection of tanks and radiators, plus inspection of pump piping, connections and heat exchangers for leaks, catch oil leaks early.
review note: review: partial - The passage covers leaks in tanks, radiators, pump piping and heat exchangers and says to correct them, but it ties the periodic IR scan to finding plugged radiators rather than leaks, and never says inspection catches leaks early.

Transformer oil leak repair proposed
Leaks may be stopped by peening or welding, or by draining the tank or removing the radiator first. The source says leaks must be corrected, not ignored.
