Cables are important components in the transportation and distribution of electricity. Due to the increased need for power, but also because overhead power lines are often replaced by (underground) power cables in densely populated areas, the importance of power cables has grown over the years.

Ageing networks: consume, prolong or replace

By Hans De Keulenaer / Published on Sat, 2007-01-27 17:41

The components of electricity networks are ageing. It is expected that within a horizon of 15 years, the performance will deteriorate significantly, while the costs for operating the networks will increase enormously. The main problem is that a significant part of the population of the assets is installed in the same period, resulting in a highly concentrated number of failures in a short time.

Is it necessary to replace all transformers by high efficiency ones?

By Roman Targosz / Published on Wed, 2006-12-20 01:00

Over the past decades, losses in transformers have continued to decrease. Old transformers therefore have relatively high losses. In some cases, it may be worthwhile to consider to replace these older transformers. The cost for purchasing these new transformers needs to be recovered through electricity savings. When replacing existing transformers by high efficiency models, you need to verify whether the additional volume or weight of transformers will not cause problems.

Should I replace working motors with HEMs?

By Sergio Ferreira / Published on Sun, 2006-01-01 02:00

This is rarely economic, except for very old motors. But if you wait until a motor fails, then the economics are likely to be much more favourable, since the difference in cost between a new and a repaired motor may not be very much.
