It works by reducing the average voltage of 242V (although it can be as high as 253V), supplied from the National Grid, down to the nominal UK voltage of 230V. Most electrical equipment manufactured for Europe and the UK is rated at 220V and may operate at an even lower voltage. The process corrects the over-voltage so it corresponds with the actual needs of the on-site equipment. Typically, a 5% voltage reduction produces at least 10% in energy savings. Other benefits include improved equipment lifecycle as operating at a higher voltage reduces its durability, reduced maintenance costs and unique software that provides real-time monitoring of energy use. The system also cleans up the power supply by balancing phase voltages and filtering harmonics and transients. |
