Editorial Message
Dear Readers,
Half a year ago, in the editorial message of the magazine’s Vol. 6, Issue 1, I mentioned a discussion on the Eco-Design Regulation, held at a conference, and how that discussion catalysed some unanswered questions about the Regulation, such as the effectiveness of the total cost of ownership (TCO) which was taken as a measure for transformer specifications in the Regulation. Two key reasons for introduction of the Regulation were the reduction of greenhouse gas (CO₂) and the reduction of energy consumption.
