Efficiency and Loss Evaluation of Large Power Transformers

All power transformers have very high energy efficiency—the largest are probably the most efficient machines ever devised. However, there is still scope for improvement. Any improvement in the performance of large transformers offers the potential of genuine economic benefits because their throughput and their continuous duty mean that the energy they waste is likewise enormous.

Webinar - Nearly Zero-Energy Buildings and Offsite Renewables

Date : 29th May 2013

Summary : The energy performance of buildings is key for reaching the European Union’s very ambitious climate targets. “Nearly zero energy building (nZEB)” is the term for a building standard that complies with this ambition.

Living in 2013 we have 8 years to go until every single Member State will have to build every new building as nearly zero energy building, and even only 6 years to go for nearly zero energy public buildings.

8.6 Energy savings with special T8 lamps

It has been right three times already during recent years that the company Philips attracted attention releasing two new T8 lamps and one additional gadget. The first one was simply a compatible retrofit solution with a lower power rating for luminaires equipped with both magnetic or electronic ballasts – but which prove to be not quite as simple as that.

The end-users as starting point for designing dynamic pricing approaches to change household energy consumption behaviours


The increasing deployment of intermittent resources, decentralised generation, and the expectation of further electrification pose a number of challenges to DSOs and TSOs in relation to the balance of supply and demand. The increasing interest in demand reduction and demand shifting has resulted in discussions about how dynamic pricing can be used to best encourage household end-users to change their energy behaviours - more specifically to shift (and reduce) energy consumption.

Energy Efficiency Self-Assessment in Industry

Industrial companies seeking ways to reduce energy consumption often call upon external advisors to assess the energy efficiency of a plant. While this is generally a good idea, it is unwise to leave this task entirely up to the external advisor. Identification of promising opportunities for saving energy requires thorough insight into the plant’s processes and a profound knowledge of the process design. Plant engineers and operators generally have a much greater insight into their plant than external advisors.

Incentives to improve energy efficiency in EU Grids

This paper investigates the energy efficiency aspects in the network design and operation based on the Energy Efficiency Directive (2012/27/EU) and its provisions related to network tariffs and regulation.

The analysis on the possible technical efficiency measures to reduce losses (chapter 2), shows that a variety of both equipment replacement and operational improvements can lead to greater efficiency.

Case Study: Dynamic modeling of the performance of safety electrical circuits during a fire

The conductivity of copper is a factor of 5 less during fire. However, this is not taken into account in the current fire safety standards for cables. Consequently, a simulation case study was carried out on safety cables during a fire based on the design data of an actual large building—the GaleriaTarnovia shopping mall in Tarnow, Poland—in order to investigate cables’ properties in this situation and ensure future cable effectiveness.
