What are the requirements specified in iec 296 transformer oil specification?

The IEC 296 transformer oil specification outlines several key requirements for mineral insulating oils used in power transformers. These include parameters such as dielectric strength, viscosity, flash point, pour point, and acidity. Additionally, the specification mandates limits on water content, sediment, and oxidation stability to ensure optimal performance and longevity of the transformer. Compliance with these requirements is crucial for maintaining electrical insulation and preventing transformer failures.
