This is the second e-lesson in the entire course and on basic / introductory level. To see the entire syllabus, consult the Transformer oil course brochure. Then you can choose the level which suits your needs best.
This lesson covers the critical functions and desired properties of transformer oil during its lifetime. The oil faces adverse conditions like heat, moisture, and oxygen that can degrade its performance. Key properties like viscosity, thermal conductivity, and dielectric strength are crucial for cooling, insulation, and stability. Measurements like dielectric dissipation factor and acidity provide insights into oil contamination and degradation. Compatibility with transformer materials and the oil's role as an information carrier on transformer health are also discussed. Environmental and safety considerations like fire point and recyclability are important requirements. The lesson concludes by highlighting the importance of understanding international standards for transformer oils in the next session.
