Voltage Optimisation

Voltage Optimisation

In the UK Voltage Optimisation / Voltage Power Optimisation is a particularly effective means of saving energy due to the national problem of over consumption of power used by electrical equipment. The declared electricity supply in the United Kingdom is now, as a result of European Harmonisation in 1995, 230V with a tolerance of +10% to -10%.

This means that supply voltage can theoretically be anywhere between 207V and 253V depending on local conditions. However, the average voltage supplied from the national grid (in mainland UK) is 242V, compared to the (nominal) average European voltage of 220V. (The average supply voltage in Northern Ireland is around 239V, and 235V in the Republic of Ireland.) Therefore, most electrical equipment manufactured for Europe and the UK is rated at 220V and may operate satisfactorily at voltages down to 200V.

By efficiently bringing supply voltages to the lower end of the statutory voltage range, voltage optimisation technology could yield average energy savings of around 13%, and the prolonged life of the connected equipment Over – voltage refers to voltage higher than the voltage at which equipment is designed to operate most effectively.

It causes a reduction in equipment lifetime and increases in energy consumed with no improvement in performance. The 17th edition of the Electricians Guide BS7671 makes the following statements in relation to overvoltage: “A 230V rated lamp used at 240 will achieve only 55% of its rated life” “A 230V linear appliance used on a 240V supply will take 4.3% more current and will consume almost 9% more energy.”
