What are the technical aspects of substation transformer oil containment?

The technical aspects of substation transformer oil containment involve designing systems to prevent oil spills and leaks, ensuring environmental protection and compliance with regulations. Key components include secondary containment structures, such as bunds or dikes, which must be impermeable and capable of holding at least 110% of the transformer’s oil volume. Additionally, regular monitoring and maintenance of containment systems, along with the use of oil leak detection sensors, are critical for early identification of potential failures.
