Voltage optimisation does pretty much what it says on the tin. The 2003 European harmonised standard for single phase voltage distribution is nominally 230 volts. Since that date all electrical equipment manufactured for a customer within the EU zone must comply with the new European Directive and be designed to function at the harmonised voltages.

The problem is that many electrical distribution networks especially in the UK have not upgraded their power distribution systems to deliver electricity to customers at the harmonised standard. This means that for the majority of sites equipment such as machinery, fans, motors, lifts, refrigeration, pumps, lighting, computers and everything else powered by electricity is being operated at a higher voltage than its design rating.

The main consequences of this situation is reduced operating life of the equipment and customers incurring higher energy costs to run the plant than what otherwise would have been the case.

One of the duties carried out by Epsilon as part of the site survey shall be to accurately measure the voltage at several locations in the premises and determine precisely how much saving in energy may be made by the installation of voltage optimisation equipment.
