On 21 May 2014, the European Commission adopted Regulation (EU) n° 548/2014 implementing Directive 2009/125/EC with regard to ecodesign requirements for small, medium and large power transformers.
It entered into force on 11 June 2014 and shall start applying from 1 July 2015.
Regulation (EU) n° 548/2014 applies to power transformers with a minimum power rating of 1 kVA used in 50 Hz electricity transmission and distribution networks or for industrial applications. Ecodesign requirements have been defined according to the types of transformers identified in table that can be viewed in the above linked PDF file.
1. Specific ecodesign requirements (two phases: from 01/07/2015 and from 01/07/2021)
Small power transformers: No specific ecodesign requirements.
Medium power transformers: Ecodesign requirements are related to maximum allowed load and no-load losses or to minimum Peak Efficiency Index (PEI) values depending on the type of medium power transformers.
Large power transformers: Ecodesign requirements are related to the minimum PEI values only.
There are other types of transformers which are not covered by specific ecodesign requirements due to their specific function (see art. 1.2 of the Regulation). However, they are covered by information requirements.
2. Product Information requirements (from 01/07/2015)
Information requirements shall be included in any related product information, including manufacturers’ free access website, and, in some cases, on the rating plate of power transformers.
