Transformer Oil – e-lesson #3 – International Oil Standards – Basic Concepts and Key differences

This lesson provides an overview of international standards for transformer oils, including key differences between the IEC and IEEE standards. It covers the functional requirements of transformer oils, such as heat dissipation and electrical insulation, and discusses important oil parameters like viscosity, pour point, and dissipation factor. The lesson also examines the recent revisions to the IEC 60296 standard, including the integration of virgin and recycled oils, and compares the specifications and emphasis of the IEC and IEEE standards. Additives and their role in improving oil stability are discussed, as well as the differences between paraffinic and naphthenic transformer oils. The presentation concludes by summarizing the main takeaways and addressing audience questions on topics like the correlation between oil properties.
