Voltage optimisation is an electrical energy saving technique which is mainly installed in series with the mains electricity supply to provide a reduced supply voltage for the site's equipment. Typically, voltage optimisation can improve power quality by balancing phase voltages and filtering harmonics and transients from the supply, although not always. Voltage optimisers are essentially transformers used to deliver power at a reduced voltage from the raw mains supply.







Electrical equipment is designed to accept a wide range of input voltages about its nominal design center. However, if the actual supply is higher than necessary the equipment will consume more power than needed and in many cases, equipment life is reduced, effectively increasing the cost of ownership.

A 230V linear appliance operated at 240V will consume approximately 9% more energy than necessary. A voltage reduction within statutory limits can produce up to 25% (subject to load) reduction in energy consumption and in addition will extend the life of many types of electrical equipment.

By reducing supply voltages to a controlled, site adjustable level, our Voltage Optimization Unit (VOU) allows equipment to operate at optimum efficiency. The result is lower overall running and ownership costs and reduced carbon footprint – each kWh of electrical energy saved is equivalent to 0.537kg of CO2.

Most VO units are installed in commercial premises, in between the raw mains transformer and main low voltage distribution board. However, this provides for no selectivity and in electrical engineering terms is considered a poor solution. A full study should be undertaken by the facilities manager and VO company , to select which supplies could benefit the owner by reducing the voltage and which supplies would give no commercial benefit. This way the owner only purchases a VO of the correct size and not one that's for all supplies. Installing a VO unit to optimise all supplies would give a longer return on investment, a higher capital outlay and makes no commercial sense.
