Laborelec at the 2013 CIRED Conference

From June 10 to 13, 2013, Laborelec will play a prominent role in the 22nd CIRED Conference in Stockholm (Sweden). CIRED is the leading forum for the international electricity distribution community and is dedicated to the design, construction, and operation of public distribution systems and large installations using electrical energy in industry, services, and transport. Laborelec has always been a major contributor to these conferences. For this year’s edition, Laborelec will have six experts presenting eleven papers in the fields of network components, power quality, planning of power distribution systems, and the electricity marketplace and impact of regulation.

For more information and a complete overview of all the papers that will be presented: www.cired2013.org

What are the limits to reducing power grid loss?

Multidisciplinary investigation uncovers issues for African grid operator

Can grid losses be limited to 6 percent for a local grid that experiences proportionally increasing loads? That was the challenge Laborelec accepted from the grid operator of a rapidly expanding African metropolis. The limitation of grid losses is necessary in order to extend the grid operator’s management contract until 2014.

Assessing the impact of a new high voltage (HV) power line

Belgian HV grid operator Elia is planning the installation of a 380 kV line between the cities of Lillo and Zandvliet. Many companies located in the region between these cities have contacted Laborelec regarding the impact of the planned HV line on their pipelines. Laborelec has started carrying out assessments at each industrial site, especially focusing on the safety of staff that are in contact with the pipelines, as well as on pipeline corrosion.

Get more out of your transformer

Transformer solutions, from purchase till end-of-life

How can one select the best transformer, take the correct maintenance actions, and deal with equipment failure? Laborelec has developed a transformer package that offers advice and support for all kinds of transformers throughout their entire lifetimes. This enables industrial customers to reduce unforeseen future costs and get more out of their transformers.

Alliander confirms trust in Laborelec’s cable quality assessment

The Dutch distribution network operator Alliander has renewed its contract with Laborelec for quality checks for its medium voltage cables. Laborelec uses an accelerated water tree test that makes it possible to better monitor cable condition, increase cable availability, and evaluate the quality of new cables. Quality assessment is becoming more and more important as cables are increasingly ageing and experiencing more stress due to growing decentralized energy production. In addition, new cable manufacturers are entering the market, but their quality is not yet known.

Presenting new transformer ageing method at Cigré in Paris

Laborelec is one of the few laboratories worldwide that has developed a method for using methanol as an ageing marker for transformer insulating paper. The method allows for more accurate condition and lifetime assessment of transformers, including the new generation. We have already applied the method in the nuclear sector and were invited to present the results of our first application at the 2012 Cigré (International Council of Large Electric Systems) Session in Paris.

Laborelec has been selected to monitor the performance of 75 electric vehicles

A Dutch consortium consisting of the city of Rotterdam, Stedin, and Eneco has selected Laborelec to monitor 75 electric vehicles (EV). The goal is to gain insight in the vehicles’ energy consumption, their energy exchange with the electrical grid, and the loading behaviour of their batteries. Laborelec’s experience with EVs was a main contributor to its selection. Our experts are actively involved in EV research; for instance in the Flemish LINEAR project. We are also conducting an EV monitoring campaign for Electrabel and Cofely Services.
