Loss Measurements on Power Transformers and Reactors

By 2020 the EU aims to reduce its CO2 emissions by 20%. Improving devices that deal with large amounts of energy could significantly contribute to this goal, as even small increases in efficiency can lead to substantial reductions in energy waste. Estimates suggest, for example, that the equivalent of half of Denmark’s total electricity consumption could be saved simply through more efficient grid power transformer designs. To help implement such changes, the European Ecodesign Directive requires power transformer and reactor manufacturers to prove that their products comply with efficiency regulations to reduce grid losses. However, precise and reliable loss measurements remain a challenging task.

This project will establish highly accurate loss measurement systems for transformers and reactors, and develop prototype devices that significantly reduce measurement uncertainty. By enabling European manufacturers to produce high quality grid components and demonstrate compliance with the Ecodesign regulations, manufacturers will be able begin making steps toward meeting the EU’s 2020 energy objectives.
