The theory behind voltage optimisation is simple.
There is a difference between the voltage supplied to a building in the United Kingdom and what is required to operate electrical equipment. On average the voltage in the United Kingdom is 242V and due to electrical equipment being manufactured to work anywhere in the European Union, this means that the optimum operating voltage required by electrical equipment to work most efficiently is around 220V.
This overvoltage is not only costing more than required, it can also shorten the life of electrical equipment. The surplus voltage produces additional heat, noise and vibration in appliances, causing stress on components, especially to motors, electronic systems like computers and lighting which are more vulnerable to over voltage and fail much sooner.
A VoltAce voltage optimisation system makes sure that a building only consumes and pays for the voltage level that it really needs rather than the overvoltage supplied from the grid. It does this by optimising the incoming voltage by up to -25V. This lowers electricity consumption, reduces electricity bills and reduces the wear and tear on appliances and electrical equipment. Voltage optimisation has the best results in organisations which have a high usage of electrical equipment. We adhere to guidance from the Carbon Trust

“A 230V linear appliance used on a 240V supply will take 4.3% more current and will consume almost 9% more energy …and … only achieve 55% of its rated life”

Voltage optimisation will not achieve any savings in High Frequency(HF) lighting, or thermostatically controlled equipment such as kettles or similar resistive loads. Savings on motors with variable speed drive controls (invertors) will also be lower than with fixed speed motors (4% to 8% instead of 12% to 20%). But it will achieve significant savings on motors, especially if these are not loaded at 100% of their capacity at 100% of the time.
