ABB, the leading power and automation technology group, is well prepared for the new ecodesign transformer regulations that came into force within the EU`s internal market in June 2014. All new transformers put into service in the EU must fulfil minimum energy efficiency requirements from July 1, 2015, giving the industry and market a period of grace of less than one year to adapt.Large amounts of power pass through transformers, which account for 30-40 percent of the losses in transmission and distribution systems. Even a marginal increase in transformer efficiency can significantly reduce CO2 emissions.The new EU ecodesign regulation covers small, medium and large power transformers used in electrical transmission and distribution networks, and for industrial applications. However, it does not apply to all transformer products; for example, single phase transformers are unaffected.The new legislation is intended to prevent high loss transformers from being installed in the EU, but the first phase (Tier 1) of efficiency requirements that come into play in July 2015 are only the start. By 2021, a Tier 2 standard will require transformer designs to be about 10 percent more energy efficient than Tier 1.
