What are the requirements for transformer oil containment design?

In transformer oil containment design, it is essential to ensure that the containment system is capable of holding the entire volume of transformer oil, accounting for possible leaks or spills, and must be constructed from materials resistant to oil degradation. The design should provide adequate freeboard to accommodate potential rainfall and avoid overflow, alongside ensuring compliance with local environmental regulations. Access for inspection and maintenance is critical, requiring easy entry points. The containment area should also include a secondary drainage system to manage any accumulated water or contaminants, while facilitating ease of cleaning and regeneration of oil. Attention to proper drainage and ventilation is crucial to prevent environmental hazards, following best practices in industrial oil management.
