EU Regulation No. 548-14 on energy performances of power transformers

Teacher Angelo Baggini

Description

On July 1st 2015 the new European Regulation N 548/14 on power transformers entered into force. Also, it is the first time ever in the World when minimum energy performance of large power transformers has been regulated.

The Regulation establishes ecodesign requirements for placing on the market or putting into service power transformers with a minimum power rating of 1 kVA used in 50 Hz electricity transmission and distribution networks or for industrial applications.

Transformers are strategic assets in the electrical networks, playing an important role in achieving the ambitious energy efficiency targets set by the most industrialized countries. Considering Europe only, 16,7 terawatthours (corresponding to 3,7 megatons of CO2) will be saved in 2025 through reduction of no-load and load losses.

Although transformers are among the most efficient electrical devices, even slight improvements in their energy performances shall be highly valued, considering the amount of installed units and the fact that they are designed to operate for decades before being replaced.

In this lesson the requirements, the exceptions and market surveillance consideration of the regulation are presented and discussed in details.

Target Audience

energy regulators, energy market surveillance staff, transformer specialists
