EU EcoDesign product information

  • The EcoDesign Directive of the European Union and the related Regulation 548/2014 for transformer losses requires manufacturers to publish on the internet information on rated power, load loss, no-load loss and weight and type of the major components of typical transformers, which are compliant with the Regulationon. Such typical values are specified under EU EcoDesign product information for Tier 1 requirements.
  • Load loss and no-load loss values are maximum values with 0% upwards tolerance. If a value exceeds at factory routine testing the maximum value, the transformer is not compliant with the Regulation and it is not allowed to use it in the EU.
  • Note that the values indicated for the weights depend on each sepcific transformer specification and may vary. The values also depend on the exact grade of electrical steel to be used. Transformer designs and materials used are constantly changing with changing materials prices.
  • Hitachi ABB Power Grids can also provide transformers according to Tier 2 loss requirements and even lower losses. Hitachi ABB Power Grids is the leading manufacturer for ultra-efficient transformers, as a company being itself fully dedicated to energy efficiency, and able to consult you for energy efficiency and sustainability.
