How is spill containment managed for oil filled transformers?

Spill containment for oil filled transformers is managed through the implementation of secondary containment systems, such as bunds or dikes, designed to capture any leaks or spills. These systems are typically constructed from impermeable materials to prevent oil from contaminating the surrounding environment. Regular inspections and maintenance of the containment structures are essential to ensure their integrity and effectiveness in managing potential spills from oil filled transformers.
