Maximising energy savings EMSc ltd is improve energy efficiency ratings with VO
A high voltage transformer utilising electronic-dynamic technology to provide a variable voltage output can help achieve better efficiency and higher energy savings on any site – even new builds, says Phil Newell UK sales manager at EMSc (UK) Ltd.

n the campaign against rising energy costs, architects have to be pragmatic in their approach and are treating energy considerations as a critical factor in their designs. One solution available to them that is immediately beneficial and easy to implement is voltage optimisation, an electrical energy saving technique in which a device is installed in series with the mains electricity supply to
provide an optimum supply voltage for a site's equipment. While the principles of the technology are generally understood and accepted, the reality is that not all voltage optimisation systems are created equal. In addition, as each building is different, with its own unique infrastructure and specific load requirements, a bespoke voltage optimisation solution is required to maximise the benefits. With the latest voltage
optimisation technology – a low- loss amorphous core high voltage transformer, which, combined with electronic-dynamic technology ensures that voltage is supplied to a site at a constant, stable level regardless of the input voltage instability. This guarantees that when the grid voltage varies the technology is able to hold the site voltage at the optimum level and maintain a higher level of savings – a vital feature for sites with critical loads, secure data and important operations that require high levels of reliability and security such as supermarkets, data centres, hospitals, hotels, education facilities and retail outlets.
What sets this system apart is its amorphous metal core. Older transformers have high levels of standing losses and the majority of modern transformers used on commercial sites use Cold Rolled Grain Oriented steel within their core, which result in significant losses for buildings in comparison to amorphous steel transformers. The solution is ideal for sites with older transformers, and those that have previously been faced with physical space restrictions that make voltage optimisation installations difficult to implement. It is also particularly relevant for new build developments where, until recently, voltage optimisation systems appeared to offer fewer savings benefits than other sustainability measures. Here, it can be a valuable tool in helping new build projects achieve sustainability marks and high energy efficiency ratings through accreditations such as BREEAM, the world’s leading design and assessment method for sustainable buildings. In addition, the system is fully designed and manufactured in the UK to be 98 per cent recyclable – an important BREEAM
measurement.
In terms of savings the super low-loss transformer coupled with electronic-dynamic intelligent voltage optimisation technology reduces standing losses by up to 75 per cent and offers annual energy consumption savings of 12 per cent. It also offers benefits such as reduced carbon emissions, guaranteed savings, simple installation, and a payback period of less than five years. While architects are increasingly incorporating voltage optimisation into their designs, it is important that they consider the different options available – the right system will deliver on its energy and carbon reduction promises, and offer a host of other benefits to boot. ■
