The oxidation stability of transformer oil is a critical factor in determining its performance and longevity in electrical systems. It refers to the oil’s ability to resist oxidative breakdown when exposed to heat, oxygen, and moisture over time. Oxidation can lead to the formation of acidic compounds, sludge, and varnish, which can compromise electrical insulation and lead to failures. Regular monitoring through methods like online dissolved gas analysis of transformer oil can help identify early signs of oxidation and potential issues, allowing for timely maintenance or oil regeneration. High-quality transformer oils often contain additives that enhance oxidation stability, extending their operational life. Proper storage and handling also play significant roles in maintaining the oil’s oxidation stability, ensuring effective performance in transformers.
