Reduced voltage in Buetzow

Tralec GmbH - BU EcoMaxx

BUETZOW - The Eckernfoerder road was explained now as the test area for Buetzow. The city in Mecklenburg-Western Pomerania examines if energy cost of street lighting can be reduced significantly through the installation of additional technology. Therefore streetlights in Buetzow are run with reduced voltage since middle of December 2007.

A compact coil, a relay and a bit of electronics - this together constitutes in principle the system EcoMaxX. "The savings coil reduces the voltage of 230 V by ten per cent down", explains Juergen Nebel. The engineer from Neuburg near Wismar is selling EcoMaxx systems, which is a product comes from Hamburg based company Tralec GmbH.

Electronics are regulating the safe operation of this system. At first the lamps are run with full tension of 230 V. "After approximately seven minutes the tension is lowered", explains Mr. Nebel. Less tension means less perfromance, less performance results in reduced energy consumption. The fact that the lamps shine less brightly is hardly to be seen, insures Mr. Nebel. He speaks of an energy conservation by 20 per cent with the system used in Buetzow. The system regulates at present 19 streetlights in the Eckernfoerder road. According to data of Juergen Nebel up to 50 lamps could be run by one system. The city paid approximately 1500 euro for the technology.

"We will see in spring after having checked the real energy if the desired saving effect could be achieved" to chief of Buetzows building authorities, Mrs.Doris Zich. The city had spent approximately 100.000 euro 2007 on the road lighting. Three years before they had spent 82.000 euro only. "In the entire city there is somewhat more than 1.000 streetlights", says electrical engineer Andreas Vigenschow.
