What are the methods for transformer oil containment in power transformers?

Methods for transformer oil containment in power transformers include the use of bunded areas, which are secondary containment systems designed to capture any leaks or spills. Additionally, oil containment systems can incorporate drip trays and absorbent materials to manage minor leaks. Regular inspections and maintenance of seals and gaskets also play a crucial role in preventing oil spills and ensuring the integrity of the transformer oil containment system.
