What are the maintenance requirements for transformer oil?

The maintenance of transformer oil involves regular monitoring of its physical and chemical properties, including moisture content, acidity, and dielectric strength to ensure optimal performance and longevity of the transformer. It’s essential to conduct routine laboratory tests to detect any degradation, oxidation, or the presence of contaminants such as particulates and dissolved gases. Regular filtration or degassing may be required to remove moisture and particulate matter, while higher levels of acidity may necessitate oil regeneration or replacement to prevent damage to the transformer components. Additionally, maintaining proper storage conditions to protect the oil from contamination during servicing and ensuring that the oil’s operating temperature remains within specified limits can significantly enhance the overall reliability and efficiency of transformers.
