E-Power – The Next Generation of Voltage Optimisation and Stabilisation What is Voltage Optimisation? Voltage Optimisation is the foundation of every energy efficiency programme. It makes the single biggest impact to assist you in achieving your energy saving and carbon reduction targets. E-power optimises voltage, dealing with the discrepancy between the actual supply voltage you receive (207V - 253V) and the optimum voltage your electrical equipment requires (220V).
Voltage Optimisation cuts your energy use and carbon emissions by 20% Voltage Optimisation cuts your energy use and carbon emissions by up to 20% and also your maximum demand by up to 15%, it also prolongs the life and reliability of all equipment in your premises that runs on electricity, this can range from a laptop to a £1m lathe.
Voltage optimisation is a unique proven technology Incoming voltage is typically between 230V-250V for sites in the UK yet the optimum operating voltage for most equipment is mainly 220V. The installation of E-power will ensure that the equipment downstream is supplied with it‟s optimum voltage thus consuming less energy than with the over-voltage conditions normally prevalent in the UK. For the first time it gives businesses, local authorities, government, manufacturers, schools and both small and large organisations the opportunity to micro manage and improve their own power supply. For example, in motors over-voltage drives the core into saturation, which wastes energy as heat. The E-power corrects this with 99.9% efficiency across its entire operating range, so the resulting savings are not offset by energy losses in the unit itself.
Voltage Optimisation protects the entire electrical infrastructure of your site Voltage Optimisation creates a more efficient, robust and reliable electrical supply for site, protecting the entire electrical infrastructure. An increasing number of electrical phenomena adversely affect and degrade equipment that, in the case of power spikes, can cause catastrophic damage. You may never have experienced these, but such spikes are on the increase and will
become more common as the national gap between supply and demand closes. To help fill this, the National Grid has to switch sources at times of high demand. An E-power unit will protect you from these spikes, all the way up to 25,000 volts.
Voltage Optimisation isn’t the same as voltage reduction Voltage Optimisation is a unique technology, designed specifically to save energy whilst addressing the problems of over-voltage and poor power quality on today‟s grid
GUARANTEED BENEFITS of Voltage Optimisation

Suppress harmful harmonics that damage sensitive equipment. 10 year guarantee and a 30-50 year life cycle. 24/7 operation and NO maintenance
WHY E-POWER ? E-power is fully controllable via the intelligent e-controller within the machine. There are 4 selectable saving modes that are accessible on the machine but can also be accessed remotely from a computer. E-power uploads and logs all consumption data to a central server where you can view real-time usage. You can overlay graphs with the real-time consumption and what the usage would currently be without E-power. This is effectively smart metering with all the benefits which also include records of all usage history. E-power is completely safe due to the patented automatic bypass. Any incurred problems which lead the conditions of the supply working outside the parameters which have been set up, will see E-power take itself out of line and ensure the incoming supply remains. If you install another form of VO kit, there is a major risk of loss of power to your building and machines which could have a direct impact on the general day to day running of your business. NO OTHER VOLTAGE OPTIMISER HAS AN AUTOMATIC BYPASS,
Voltages on the three supply phases are balanced by the regulating effect of the Epower’s unreferenced star point. Phase balancing of over 20% has been observed with E-power, which dramatically increases the efficiency of 3-phase AC motor equipment, particularly common in air distribution systems. A harmonic filter is integrated into the design of the E-power, giving attenuation in Total Harmonic Distortion (THD) and a marked reduction in 3rd, 5th and 7th harmonics. As harmonics are potentially damaging to electronic equipment and known to reduce the efficiency of HV transformers, this is an important function that delivers tangible energy-saving benefits. As a result of the improvements in power quality, a typical E-power installation will improve the Power Factor of a site between 4-10%. This may alleviate the need for additional Power Factor Correction (PFC), although the E-power is fully compatible with this type of equipment. Considerable reductions in reactive power have been achieved, often reducing penalty charges from electricity suppliers. The E-power will additionally protect a site from transients up to 25kV, these voltage spikes having a devastating effect on sensitive electronic equipment. As transients become more common, due to increased switching on the grid, this provides a vital defence for critical IT systems. E-power really is tomorrow‟s technology today and should be a consideration for all large
consumers of electricity. The KWH savings, which also translate into Co2 savings, are of particular relevance in what are both economically and environmentally challenging times.
Optimise or Reduce? The UK has a significant opportunity to save energy. As a result of European harmonisation, our equipment is manufactured to work most efficiently at EU voltage levels, about 20V below our national grid‟s average of 242V. Our over-voltage has wide ranging negative effects, from increased energy consumption to reducing lifespan of electrical equipment .
Transformers
The level of voltage can be changed with a transformer. Most transformers in use on the electricity grid are the sort of conventional 'dual wound' transformers. These have primary and secondary windings, and are used to take voltages down from the 11,000V found on the grid, to the level you need from your plug socket. For reducing your voltage to 220V, however, a dual-wound transformer is inappropriate. In terms of efficiency, cost-effectiveness - plus does not counteract such issues as the distortion effects of harmonics and transients - because a conventional transformer is not designed to do this.
Auto transformers
An alternative way of reducing voltage is to use an autotransformer. These come in two types: fixed ('tapped') and variable (sometimes known as a 'variac'). Having only one winding on each phase. The major disadvantage, however, is that neither type is designed for energy efficiency, nor neither technology was conceived with the idea that it would be installed on your mains supply: the most critical part of your electrical infrastructure. Variable autotransformers have their own problems, due to the means by which they produce a stable output voltage. Since the incoming voltage (from the grid) will always be fluctuating around a given value, the transformer has to constantly change the percentage by which it is changing the voltage. To do this, the entire electrical supply to a site must be passed through a single, delicate, moving part, making them unreliable and adding risk to your supply. With a fixed / tapped autotransformer, the problems relate to design, build quality and inherent inefficiency. The electrical load of a building varies throughout the day, and unfortunately autotransformers do not sustain their full efficiency across their whole loading range.
For example, they may be quite efficient when 50% loaded, but may get hot when the load gets higher. If the build quality is not top-notch, this poses a serious risk to your electrical supply, and the only way autotransformer suppliers have found to address this is to install a continuous online temperature monitor that alerts you if your site is at risk. Also, autotransformers cannot help improve power quality, they are simply a voltage reduction technology. E-power, however, was conceived, designed and manufactured with energy efficiency in mind and to be the new era in energy saving, bringing not just the energy saving but the “at point monitoring” and the ability for absolute control. E-power is the only machine of type to be 100% safe. E-power is a completely passive unit, with no moving parts, made from ultra-high-purity materials which give it a 99.9% efficiency or higher, from 15% - 100% loading. It has a wide range of optimisations; from 3-12% and should you need a more drastic drop, we can have units custombuilt to your specifications. Being so efficient E-power does not require cooling units and operate barely above room temperature. Without even addressing the other qualities of the E-power, on this like-for-like basis the difference between a transformer's reduction and a E-power optimisation is enormous. On top of this, E-power has various other functions that make it the only true Voltage Optimiser: harmonic suppression, three phase balancing and transient protection (up to 25,000V). Just as important as the design, though, is the construction of the unit. Construction to demanding EU standards means that E-power is developed and built in our state of the manufacturing facility in Italy using only the very best components. With E-power Voltage Optimisation you can fit the technology with absolute confidence that the integrity of your supply will be improved, and your site will be running as efficiently as possible.
90% of British organisations pay for more energy than they need So the short answer is, yes very probably. An E-power applied building will make an average saving of 13% but it can be as high as 20%.
Can you afford not to optimise your energy supply? This is a technology where the percentage Return on Investment (ROI) is typically 25% -100%. With these levels of return and fast payback everyone can afford to install the technology. Should you not have the available capital, Public sector and higher education establishments can access funding through SALIX, private companies, spending less than £500,000 per year on electricity, may qualify to borrow from the Carbon Trust to install E-power. Loans are unsecured, interestfree and repayable over up to 4 years. We can help you with these.
Can you afford to pay for up to 20% more energy than you need? Why is it necessary ? Because of the colossal hidden cost to the entire UK arising from the discrepancy between the voltage needed to run electrical equipment at peak efficiency and the actual voltage that arrives on site. You can produce savings equivalent to 5% more sales In headline terms, if your power is not optimised, you are paying for up to 20% more electricity than you need and at the same time, emit up to 20% more CO2. According to the Carbon Trust, Voltage Optimisation this is worth the equivalent of an extra 5% in sales to your business. Reduce your carbon output in line with legislation The government‟s Climate Change Bill joins other legislation designed to move Britain towards a low-carbon economy; its ambitious goal to give the UK a net carbon account for the year 2050 at least 80% lower than 1990. E-power gives you the chance to reduce your carbon output by up to 20%, literally overnight. Improving power quality protects machinery and data Most electrical equipment in the UK and Europe is designed and manufactured to run at 220V. 90% of premises have an average of 242V. Quite apart from the waste of energy this represents, without Voltage Optimisation your electrical infrastructure isn‟t protected from a range of hazards. These can produce results as gradual as the slow degradation of your IT equipment, to the potentially catastrophic loss of data or expensive machinery in a power spike – an increasingly common occurrence. Higher productivity, less maintenance, longer life Many people blame reliability problems and short life cycles on inherent faults in the product – and live with it. However electrical equipment running on a power supply that hasn‟t been optimised breaks down more often, requires more maintenance and has to be replaced sooner. The capital cost to business of replacing equipment early, coupled with the loss in productivity when it has to be maintained or repaired, is incalculable. E-power is an all-in-one solution to a number of common power supply problems. It is utterly different to auto-transformers or „variacs‟ which cannot get anywhere near - let alone replicate the reliability, versatility or savings of Voltage Optimisation technology. It requires no moving parts or electronics. E-power is truly the next generation of VO and is unmatched by any technology available in the UK today. E-power is not just a dumb machine it is intelligent, controllable and SAFE. The E-powers main feature is its ability to optimise and improve the incoming voltage for a whole site and therefore cut energy costs. This reduces energy bills and also improves the efficiency of electrical equipment.
We can supply a range of E-power to meet the needs of smaller enterprises up to the largest industrial consumers.
