What are the containment requirements for oil filled transformers?

Containment requirements for oil filled transformers are critical to prevent environmental contamination and ensure safety. These requirements typically include the installation of secondary containment systems, such as bunds or dikes, that can hold at least 110% of the transformer’s oil capacity. Additionally, regular inspections and maintenance of containment structures are necessary to detect leaks or spills promptly, ensuring compliance with environmental regulations and minimizing risks associated with transformer oil.
