Voltage optimization is an energy saving technology that is used to regulate, clean and condition the incoming power supply in order to reduce the voltage supplied to the optimum level for the on-site electrical equipment and appliances.
The concept behind voltage optimization is simple. In general, power from the energy grid is supplied at a higher voltage than necessary due to old electrical distribution networks in place which were designed to operate at higher voltage levels, as well as electricity suppliers being required to ensure all buildings are supplied voltage within set parameters.
If a building is being supplied at a higher voltage than necessary it will likely result in a mass of wasted energy, excessive levels of carbon emissions, and higher than necessary electricity bills in addition to power quality issues, including increased wear and reduced lifespan of electrical equipment.
In addition to reducing energy consumption, cutting carbon emissions and providing savings on electricity bills, voltage optimization can also improve power quality by balancing phase voltages and filtering harmonics and transients from the network operators supply.
Voltage optimization technologies are typically installed in series between the distribution transformer and the main low voltage distribution board, allowing all of the consumer’s electrical equipment to benefit from an optimized power supply.
There are two types of voltage optimization system which are generally referenced when discussing this approach; ‘Fixed’ Powerstar LITE, which optimizes the voltage by a set amount and matches the incoming profile, or ‘Electronic-Dynamic’ Powerstar MAX, which uses intelligent controls to optimize the voltage and maintain it at a constant level.
For larger sites that operate their own HV/LV infrastructure, Powerstar HV MAX can be installed on the HV side to correct the incoming power supply issues at source through replacing the current HV transformer with a super-low loss amorphous core transformer and integrating this with voltage optimization technology.
Dr Alex Mardapittas, inventor of the VIRTUE energy storage solution and Managing Director of Powerstar, emphasises how electricity supply issues have become an increasingly common problem within the UK electricity network. Recent power failures at multiple airports highlight the dangers of unprotected supplies in a world reliant on technology. With modern advances in technology, increasing...
