Design of Distribution Transformers – e-lesson #19 – Standard classes, norms, certifications for distribution and high power transformers

This is lesson number #19 in the Design of distribution transformers course, authored and hosted live by Mario Salano. It is conducted on Master's level and you can save your seat here.

The course provided an overview of the crucial role of norms and certifications in distribution and high-power transformers. It discussed the historical context of unification efforts since the 1920s to standardize core sizes and components. As power systems rapidly developed, the need for robust norms became critical, especially for energy efficiency. The course covered the IEC 60076 standard, the "Bible" for transformer norms in Europe. It delved into the Eco-Design Directive, a regulatory framework aimed at achieving better energy efficiency and reducing emissions, including ambitious 20% efficiency targets by 2021. The presentation explored the legal obligations for manufacturers, the impact on the transformer market, and the potential for energy savings through improved design. It also touched on emerging trends towards decentralization, smart grids, and solid-state transformers, and the evolving standards driving these advancements.
