What is the inhibitor content in transformer oil?

The inhibitor content in transformer oil refers to the specific additives included to enhance the oil’s performance and longevity by reducing oxidation and preventing the formation of sludge and corrosive acids. These inhibitors are crucial for maintaining transformer efficiency and reliability, as they help protect the insulating properties and overall health of the oil. Typically, the inhibitor content is formulated based on the desired lifespan of the transformer and the operating conditions, with common inhibitors including phenolic compounds, amines, and other antioxidant agents. Regular testing of the inhibitor content in transformer oil is essential to ensure optimal performance and to schedule timely oil regeneration or replacement as needed.
