The life expectancy of an oil-filled transformer typically ranges from 25 to 40 years, depending on several factors such as operating conditions, maintenance practices, and the quality of the insulating oil used. Regular monitoring and maintenance can significantly enhance longevity, as aged oil may require regeneration or replacement to ensure optimal performance. When comparing oil vs dry transformer technology, it’s crucial to note that while oil-filled transformers may have a longer service life under the right conditions, dry transformers generally require less maintenance and may offer longer-term reliability by eliminating issues associated with oil degradation and leakage.
