Maximum load and no-load losses for three-phase dry-type medium power transformers as per Regulation (EU) n. 548/2014 and 2019/1783
![Maximum Load and no load losses IMG 1](https://www.imefy.it/images/Maximum_Load_and_no_load_losses_IMG_1.jpg)
In case of different voltage ratios in the windings or in case of double voltage in one or in both windings, the load losses and no-load losses will be corrected as described in table I.3 of EU Regulation 548/14, as amended by EU Regulation 2019/1783.
Transformers with a power greater than 3.150 kVA must comply with the minimum values of the peak efficiency index (PEI) as shown in table I.8 of the EU Regulation 2019/1783.
