Investigation into the Performance of Aluminum Wound Distribution Transformers

By

Wed, 05/22/2013 - 20:31

The stresses responsible for transformer failures, creep behavior of aluminum conductor, operating conditions, frequent magnetic inrush current and their effects on the life of distribution transformer (DTs) are being investigated. It is being investigated by conducting experiments that hot spot temperature, creep behavior of aluminum conductor, and frequent switching of DTs in the field may be responsible for excessive failures.

Efficiency and Loss Evaluation of Large Power Transformers

By

Bruno De Wachter

Mon, 05/20/2013 - 23:00

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.

Fri, 05/10/2013 - 22:43

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.

Energy Efficiency Self-Assessment in Industry

By

Didier Wijnants

Tue, 05/07/2013 - 17:15

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.

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.

Heat Pumps for Larger Buildings

By

Keeran Jugdoyal

Fri, 04/05/2013 - 11:15

Heat pumps are increasingly being used in medium and large buildings to provide both heating and cooling. If specified and installed correctly they present a very good opportunity to save energy and reduce carbon emissions compared to traditional building heating and cooling technologies. This application note provides an overview of the types of heat pumps available along with the advantages and constraints of installing them in larger buildings.

While having considered the energy saving opportunities by increasing the size of cables, Japan faced the urgent needs to save energy any possible way due to the aftermath of the Earthquake and Tsunami on March, 2011. “Dual Wiring” is the immediate solution without a large scale renovation or construction, yet to get the same result of cable upsizing. This paper talks about what is “Dual-Wiring” and theoretical study behind it.

Best Practices in Designing and Implementing Energy Efficiency Obligation Schemes

By

Wed, 03/27/2013 - 15:52

An energy efficiency obligation (EEO) is a regulatory mechanism that requires obligated parties to meet quantitative energy saving targets by delivering or procuring eligible energy savings produced by implementing approved end-use energy efficiency measures. The requirement to meet quantitative energy saving targets distinguishes EEOs from other similar mechanisms, such as a general requirement to acquire all cost effective energy efficiency with no target specified.

The properties of LED lighting

Incandescent lamps are cheap but tend to have short lifetimes. The light emitted by incandescent sources is perceived as particularly pleasant because these hot radiators generate a continuous (or full) emission spectrum. Nevertheless, as hot radiators they waste much of the electrical energy supplied to them.

Spreading the Net: the Multiple Benefits of Energy Efficiency Improvements

By

Wed, 03/20/2013 - 16:43

Improving energy efficiency has long been advocated as a way to increase the productivity and sustainability of society, primarily through the delivery of energy savings. The impact of energy efficiency measures can go far beyond energy savings, and energy efficiency improvements can be an important contributor to economic growth and social development.

Nearly Zero-Energy Buildings and Offsite Renewables

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 single new building as nearly zero energy building, and even only 6 years to go for nearly zero energy public buildings.

Tue, 01/29/2013 - 18:14

Energy efficiency has been a key topic for many years now, yet there still remain opportunities to reduce energy use in existing buildings. With existing buildings making up a significant proportion of Europe’s building stock, reducing the energy they consume can help make inroads to meeting carbon reduction targets.

The year 2012 was a year of transition for the IEA Demand-Side Management Implementing Agreement. It was the last year of our current term and so we started the process of applying for an extension from the CERT.

For the Implementing Agreement that is more than going through the motions. We looked back, evaluated our work and now we are designing the path for the next five years.

The Scope for Electricity & Carbon Saving in the EU through the use of EPM Technologies

By

Thu, 01/10/2013 - 15:46

Electromagnetic processing of materials (EPM) provides significant opportunities for saving primary energy and reducing carbon emissions in industrial thermal processes. The use of electricity for industrial thermal processes has a current market share of around 10% in Europe and is divided in numerous different applications and industrial branches, where today the share between fossil fuel and electricity used as the end energy carrier is absolute different.

In the whitepaper 'Coping with the Energy Challenge / The IEC’s role from 2010 to 2030', smart electrification is seen as the key to a sustainable and efficient global energy system. By opting for renewable energy sources and using electrical energy in a smart and controlled manner, electricity can play the major roll in decarbonizing the global economy. This is not a business-as-usual scenario.

The impact of energy-saving installations in European homes on the life cycle cost

By

Tue, 09/11/2012 - 10:23

The energy-saving measures most often applied in homes relate to better insulation of the outer shell. Nevertheless, other technologies and installations can drastically drive down the energy consumption of a home. These include, amongst others, the solar boiler, heat pump, and integrated home system. Some of these less well-known techniques do even better than additional insulation, depending, of course, on the climate, the type of building (apartment or house), and the age of the building (new construction or renovation).
