Voltage optimisation is needed to purely correct supply issues caused by the High Voltage infrastructure in the UK. Voltage optimisation can reduce your energy use by up to 20% and reduces carbon emissions by up to 15%.
Why is it required?
Most electrical equipment is designed to run at 220V. However, in the UK 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.
Voltage 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.
How Does Voltage Optimisation Work?
Voltage optimisation works by reducing the voltage of the electricity supplied to equipment, minimising consumption while remaining within the operating conditions specified by the manufacturer.
After installation the incoming power from the National Grid is reduced to a level more suited for the building, typically around 220V, which results in reduced costs as the site is only provided with the amount of voltage it needs and increased lifespan on electrical equipment as it is not being overpowered by excess voltage supply.
