What is the difference between uninhibited and inhibited transformer oil in power transformers?

The difference between uninhibited and inhibited transformer oil in power transformers lies in their chemical composition and performance characteristics. Uninhibited transformer oil lacks additives that prevent oxidation, making it more susceptible to degradation over time. In contrast, inhibited transformer oil contains specific additives that enhance its oxidation stability, prolonging its lifespan and improving its overall performance in power transformers. This distinction is crucial for maintaining transformer efficiency and reliability.
