What are the containment requirements for transformer oil?

Containment requirements for transformer oil are designed to prevent environmental contamination and ensure safe operation. These requirements typically include:

Secondary Containment: Transformers must be installed within a containment area, such as a bund or spill basin, capable of holding at least 110% of the oil volume in case of a leak or spill.
Leak Detection Systems: Monitoring systems should be in place to detect any leaks in the transformer, enabling quick response to prevent oil from escaping into the environment.
Proper Drainage: The containment area should have proper drainage systems to manage rainwater without allowing oil to escape. Any oil-contaminated water should be treated before discharge.
Routine Inspections: Regular inspections and maintenance of transformers and containment areas are required to ensure the integrity of the system and to identify any potential issues before they lead to spills.
Spill Response Plans: There should be an established spill response plan, including the availability of spill kits and trained personnel to handle any oil leaks or spills effectively.
