Voltage Optimisation

Apex Voltage Optimiser2In 1995, the nominal European voltage was harmonised at 230V, as a result all electrical equipment on the market within the EU is now designed to run at 220V.

In the UK however, the average voltage supplied from the national grid is 242V, with levels ranging as high as 253V, in some premises.

This ‘over voltage’ is not only costly but can also be detrimental to electrical equipment. Excess voltage produces excess noise, heat and vibration, causing stress on internal parts and especially to motors, which are vulnerable to overheating and wear out more quickly. Equipment such as chillers and air-conditioning units use motors to run their pumps and fans, therefore particularly benefit from voltage optimisation, as do incandescent lamps and T8 fluorescent lamps.

ECO-MAX-HOME-Main-Picture-New-Label-Max-Res_300x300Voltage optimisation is also invaluable in levelling out the peaks and troughs in supply from the national grid, which can be damaging to equipment – particularly sensitive IT components. These variances in the electricity supplied are caused by jumps and falls in demand on the national grid at certain times of the day. Volatility in levels is likely to increase, as more and more solar and wind micro-generation systems feed power into the grid, making the need to maintain a steady voltage supply more important than ever.

Optimising voltage to save energy

If a site is being supplied with electricity at a higher voltage level than needed, then it will likely be wasting energy, money and be responsible for more emissions than necessary. This is where voltage optimisation can help as electrical equipment can sometimes consume more power at higher voltages.

Voltage optimisation can be used alongside many other kinds of energy saving devices, such as lighting controls, solar panels and all types of heat pumps – air, ground and solar – whilst improving energy efficiency.

Companies have been seeing the benefits of voltage optimisation for many years, and the technology is a well-established and trusted method of reducing energy costs and carbon emissions.

Voltage optimisation systems are a highly effective ‘fit and forget’ technology for residential properties and smaller commercial sites.
