Transformer Testing course – e-lesson #13: Temperature rise test

This lesson covers the important topic of temperature rise testing for power transformers. Temperature rise is a critical factor in transformer design and operation, as it impacts the lifespan of the insulation. The lesson will discuss relevant standards, definitions, and temperature rise limits. It will explain the different cooling methods used in transformers and how they impact temperature rise. The key aspects of measuring oil temperature rise and winding temperature rise will be covered, including the test setup and data processing. Additional tests like dissolved gas analysis and thermography will also be mentioned as useful supplementary techniques. This comprehensive overview will provide attendees with a solid understanding of temperature rise testing for power transformers.
