Ecotran

The European Union has established a framework for setting Ecodesign requirements for energy-related products (Directive 2009/125/EC). The main target is a 20% improvement in the EU’s energy efficiency.

In 2008 it was estimated that transformer losses amounted to 93.4TWh per year. In contrast, by 2025 the savings in losses has been estimated at 16.2TWh per year by using Ecodesign transformers. This equates to a CO2 emissions saving of 3.7Mt.

What this means to our customers

The lower losses are achieved by using lower flux density in the iron core, lower current density in the copper or aluminium windings, and grades of core steel, which have lower specific losses than standard grades coupled with innovative design techniques. In essence, these changes mean that more active material has to go into the manufacture of the transformer. In order to comply with the requirements of the Ecodesign Directive, Winder Power has developed a range of innovative transformer designs in Ecotran that do not unduly increase the selling price of low loss transformers.

TransformerThe main advantage to the customer is that their power consumption will be reduced providing cost savings and an improvement in CO2 emissions. The Ecotran transformer range will also have much lower noise levels due to the reduced flux density in the core.


Typical Cost Savings of the Winder Power Ecotran transformer

  •  Savings of circa £4.5k per annum through improvement of combined transformer losses.
  • Potential savings of 8-10% through enhanced output voltage adjustment.
  •  Substantial reduction in CO2 emissions of circa 19 tonnes per annum.

With 12 years expertise to call upon in this area the design team is already actively working on the next generation of efficiency and performance gains, which will offer even greater savings to customers.
