Energy Transition and Circular Economy-related regulations are popping up around the world. Both energy efficiency and material efficiency are to be optimised. In electrical applications it is not always apparent how a trade-off between these goals can be avoided. The sustainable peak load concept for public distribution transformers does exactly that: it is beneficial to transformer energy efficiency as well as material efficiency, with no need for compromise.

This webinar will present the concept, several case studies, a thorough transformer loading survey carried out in US and a modelling exercise for the EU.

Key messages

• The total annual energy losses of a sustainable peak load unit are similar to those of a conventional unit. This is due to the fact that the average loading in public distribution networks is low, resulting in a higher relative importance of no-load losses compared to load losses.
• The material savings potential of sustainable peak load transformers is substantial, with reductions in total weight of 11 – 15%.
• The purchase cost of a sustainable peak load transformer is comparable to that of a conventional transformer if all other parameters are kept the same.
