What is a Voltage Optimisation or Reduction Device?
The supply voltages to sites can vary dramatically over time and the distribution of electricity on site can further affect voltage e.g. a building at the far end of the site may have a much lower voltage than the site supply. This seriously affects the efficiency of rated equipment and savings are possible. Voltage reduction devices are often applied to the site supply, individual building supply and individual areas of equipment such as lighting. The concept makes use of the fact that all electrical devices are designed to operate at main voltage [today usually 220 v ac] within a tolerance. By reducing the voltage to the minimum permitted within the design tolerance the power used can be reduced thus saving energy without affecting the performance of the energy consuming equipment. Most devices allow systems to start on unreduced voltages and then control the voltage once stable operation has been achieved.
