What are the technical aspects of transformer oil uninhibited?

Uninhibited transformer oil lacks additives that prevent oxidation and degradation. This type of oil is typically less expensive but has a shorter lifespan due to increased susceptibility to moisture and thermal breakdown. The absence of inhibitors can lead to the formation of sludge and acids, compromising insulation properties and overall transformer performance. Regular monitoring and maintenance are essential to mitigate these risks and ensure reliable operation of transformers using uninhibited oil.
