How powerPerfector was able to help Manchester Hilton Hotel

Following a process of evaluation to confirm the level of Optimisation and suitability of the Manchester site for a powerPerfector unit, a pP560kVA / 800A unit was installed. A scheduled shut down of the site was required, with the work carried out over a weekend. Following installation all electrical equipment has operated normally and there have been no reports of any problems. With further observation over time, our clients tell us that equipment life can be noticeably extended. The hotel has a varied load, with televisions; heating, ventilation and air conditioning, and lighting circuits. The hotel is likely to have a high load factor considering the long working hours.

Getting the source right

powerPerfector is the world’s only Voltage Power Optimiser, giving  energy, carbon and cost savings by efficiently optimising a site’s supply voltage. By optimising the voltage, electrical equipment runs more efficiently and consumes less energy. The declared electricity supply in
the United Kingdom is now, as a result of European Harmonisation, 230V with a tolerance of +10% to ‐10%. This means that effective voltage can be anywhere between 207V and 253V depending on local conditions. Most electrical equipment manufactured for Europe and the UK is rated at 220V and operates more efficiently at this level. Forcing appliances to operate at a higher voltage in the UK (242V is the average supply level) leads to significantly higher energy consumption, increased heat losses and a reduced life span. As a result of equipment specification and the range of voltage supply, there is an opportunity to achieve cost savings by optimising voltage at source and at the same time improve the operation and lifespan of a site’s electrical infrastructure. It is estimated that 90% of sites in the UK are operating at too high a voltage and could therefore benefit from installing a powerPerfector.

Voltage Power Optimisation. The less obvious benefits

Reduced maintenance, longer life
All electrical equipment has an optimum voltage at which it works best. A powerPerfected supply delivers that optimum and reduces the strain on your electrical equipment, leaving it to work more reliably and for longer.

Better quality power supply
Some things you may have accepted for years, but product faults can turn out to be caused by a poor quality power supply. For instance, the life of incandescent light bulbs is almost doubled when the supply voltage is optimised. Now imagine that in relation to an IT network or an expensive piece of manufacturing equipment.

Missing the penalty kick
Power factor penalty charges – which are now uncapped in the UK – can be avoided if your power factor is above 0.95. If your power factor is at around 0.9 at the moment, powerPerfector could remove your exposure to these charges by improving the electrical efficiency of your site. 

Lower harmonic distortion and reduced neutral currents
powerPerfectors are able to filter harmonics on the mains incomer. Harmonic distortion is on the increase and can lead to random failures of electronic equipment – particularly computers.

Protection
Common transients – very brief spikes in voltage from the grid – are eliminated by powerPerfector. Transients at this level can cause catastrophic damage to equipment, but smaller, more common transient events will also shorten the life expectancy of electrical equipment over time.
