What are the design specifications for transformer oil containment?

The design specifications for transformer oil containment typically include a secondary containment system capable of holding at least 110% of the transformer’s oil capacity. The containment area should be constructed from impermeable materials, such as concrete or steel, to prevent leaks. Additionally, it must incorporate drainage systems to manage rainwater and potential spills, and comply with local environmental regulations. Regular inspections and maintenance protocols are essential to ensure integrity and functionality.
