Ecodesign Transformers

Slaters supplies new three-phase distribution and power transformers that comply with Tier 1 of EU Ecodesign directive 548/2014, implemented in July 2015.

For decades many transformers have been designed for peak efficiencies of around 98-99%. This directive banned less efficient designs by setting maximum permissible energy losses for all new transformers placed in the market. New transformers over 500kVA are now more than 99% efficient.

From July 2021, Tier 2 of the directive requires a further reduction in energy losses, thereby increasing transformer efficiency incrementally by about 0.33% for 500kVA’s and 0.05% for 20MVA’s.

The legislation covers all EU countries and we expect this standard to survive within UK, post Brexit. Similarly, the US Department of Energy required a 2-tier increase in transformer efficiencies in 2010 and 2016.

The directive does NOT apply to existing installed transformers, nor secondhand transformers reinstalled in to service.

Eco Transformer for Anaerobic Digestion Plant

Eco Transformer for Anaerobic Digestion Plant

  • Slaters 2.5MVA ecopower eco design HV distribution transformer installed
  • Ecopower transformer allowed step-up in voltage from 433V to the 11,000V
  • Installation of the new transformer was completed within eight weeks of the initial order
Neil Hunter, managing director at Local Generation, said
"Slaters impressed us with their technical knowledge and expertise. This alongside the short lead times and quality of the response to our initial enquiry, helped to secure the order."
