European Union (EU) regulation in the area of ecodesign is evolving to meet the requirements of the Ecodesign for Sustainable Products Regulation (ESPR), which places greater emphasis on the circular economy. This leads to the question of whether the energy performance levels of distribution transformers should be further improved. The answer must take the wider context into account, basing its calculations over the entire lifetime of the units concerned and including the impact on power generation capacity needs. After garnering fresh insights, the International Copper Association has reviewed and fine-tuned its earlier analysis published in the April 2024 edition of Transformers Magazine. The new assessment, comparing a range of scenarios and design strategies, identifies the most favourable options, offering a 5% reduction of no-load losses and a 10% reduction of load losses compared to prevailing values.
