Why is ester oil used in transformers and how is it processed?

Ester oils are used for their biodegradability, high flash point, and thermal stability, making them safer than mineral oils. GlobeCore systems filter and degas ester oils to maintain their quality and extend transformer service life.

Ester oils are increasingly favored in transformers due to their excellent biodegradability, high flash point, superior thermal stability, and non-toxic nature, which enhance safety compared to traditional mineral oils. The processing of ester oils involves filtration and degassing, essential for removing impurities and moisture. GlobeCore systems effectively filter and degas these oils, ensuring optimal performance and extending the service life of transformers by preventing degradation and maintaining electrical insulation properties. Regular maintenance with these systems can significantly improve transformer reliability and efficiency.
