By carefully controlling the voltage supplied to a premises or site by installing appropriate equipment, significant savings in the cost of operating electrical equipment can be achieved without compromising the operational effectiveness of plant and equipment.

A proven technique which has been understood for many years and reduces incoming voltage levels in a controlled way is loosely termed as Voltage Optimisation

In 1996 The Institute of Electrical Engineers (IEE) recommended that for safety, all electrical equipment is tested across the range 198V to 253V and should be capable of working within these voltage levels.

Voltage Optimisation Benefits and Savings

  1. BulletReduces energy consumption by up to 20%

  2. BulletReduces carbon emissions (see latest CRC legislation)

  3. BulletReduces circuit currents

  4. BulletReduces harmonic distortion

  5. BulletReduces Maximum Demand and Capacity Charges

  6. BulletImproves electrical efficiency (power factor)

  7. BulletImproves plant utilisation

  8. BulletExtends the life of electronic components and plant

  9. BulletProtects from Transients, Spikes and Surges

Light Circuit Energy Reduction - by Voltage Optimisation

Whilst our technology can reduce energy across a number of disciplines, in some applications such as Storage Facilities, Parking Facilities and Operations that rely on a high degree of lighting, the main reduction in energy may be gained form optimising the lighting circuits alone to maximise a return on the investment by targeting the areas that benefit the most. The system also works for highway and street lighting!

Voltage optimisation operates on the principal that it takes a certain level of voltage to ‘strike‘  or light a lamp and a much lower voltage to run a lamp with minimal or no detriment to the lighting levels or ‘Lux’.

Our lighting power optimiser can be matched to the demands of individual lighting circuits and is available for both single phase and three phase applications.

The technology is fully automatic and fully adjustable to enable the user to extract maximum savings form this proven technology.

Maximum savings are usually gained on the more common types of lighting and while the technology works on all types of lighting, it is less likely to return substantial savings on high frequency lighting.

Supply voltage can vary widely across the UK dependant largely on where your site or facility sits within the transmission grid. In the UK, voltage supplies have been standardised for many years at 240V +/- 10% whereas European supply voltages have been lower at 220V nominal.

Since June 2008 supplies have now been harmonised across UK and Europe at 230V (+/- 10%) i.e. 207 to 253 volts.  Some EU countries, including the UK, have adopted a stricter requirement of +10%, -6% (ie 216 to 253 volts)However, the average voltage across the UK is 242 volts due mainly to the constraints of the supply networks. This results in electrical equipment and plant operating well above the necessary voltage and causes higher energy costs, excessive kW/h losses and reduced life of electrical and electronic components.
