What is the design of a transformer oil soak pit?

The design of a transformer oil soak pit typically includes a containment area constructed from impermeable materials to prevent oil leakage. It features a sloped bottom to facilitate drainage and collection of spilled oil. The soak pit is often lined with gravel or sand to enhance absorption and filtration. Additionally, it may incorporate a drainage system connected to an oil-water separator to manage any contaminated runoff effectively, ensuring environmental compliance.
