Voltage Optimisation Devices

Voltage Optimisation Devices


The installation of domestic energy efficiency measures, such as Voltage Optimisation Devices and Smart Meters, is being boosted significantly by the Government’s Carbon Emissions Reduction Target (CERT) programme.


CERT expects to stimulate spending of up to £1 billion on intelligent energy saving equipment and ‘green technology’ over the next three years.


Reducing Energy Consumption

The UK electricity distribution network operates at a nominal 230 volts AC, although in practice average voltages are more likely to range between 240 and 245 volts AC.   Most household appliances are now designed to operate efficiently at 220 volts.  A 220V appliance used on a 240V supply will draw more current and will consume around 9% more   energy.  Therefore energy savings can be made by optimising and reducing the supply voltage within electrical installations.

Voltage Optimisation Devices can regulate mains voltage to a stable level, normally 220V in the UK, regardless of the incoming supply voltage.

The amount of energy saved is device specific and claims vary up to 15%.   Results show expected average reduction in household electricity bills of up to 10% but their effectiveness in domestic installations have been questioned.


VPhase is developing a range of energy saving Smart Voltage Management products based upon voltage reduction and stabilisation such as the VX1.


By working in conjunction with the consumer unit the VX1 reduces and regulates voltage on selected circuits that are most likely to deliver greatest savings.


Government Trials of these units are to be carried out in the UK during 2009/10.


The VPhase claim that their Smart Voltage Management devices can provide home owners and businesses considerable reductions in electricity costs, energy wasting and carbon emissions from generation sources.

I understand that a voltage drop develops within the optimizer to achieve the optimized voltage, What is the max %age V.D. with respect to the input voltage? Do you have taps on the out put side of the optimizer for different out put voltages?
