LED drivers, essential to the performance of any LED lighting, need to be sufficiently flexible to adapt to different conditions. Markus Rademacher of Tridonic explains how new technologies are helping

Readers will clearly be aware that at the heart of every LED luminaire is an LED driver and that the most important parameter of the LED driver is the output current. Essentially, in an LED circuit, mains voltage is converted to a constant voltage and the LED driver then converts this to a constant current. This current determines the operating temperature and therefore the lifetime of the luminaire.

Simplexity, or simplification of complexity, is the process of tying all the necessary IT, communications and support infrastructure equipment necessary for a data centre into easily deployed, scalable and manageable solutions. David O’Coimin, solution offer manager at Schneider Electric UK, explains

For anyone purchasing electrical equipment, the time-honoured way to do business has been via the electrical wholesaler and visits to the trade counter have become a part of a their everyday life. But the evolution of the electrical industry and the introduction of technology such as iPads and Smart phones mean that contractors have an expectation about the way they are able to do business

Measure for measure

My many thousands of devoted readers will recall that, over the years, I have become increasingly sceptical about the overall cost of the government’s commitment to see 53 million so-called smart meters installed in British homes and businesses in the next five years. I can quite see the value of the exercise to the Big Six electricity companies, who will be able to dispense with both meter readers and telephone complaint operatives. Confident that all bills sent to consumers will henceforth already be completely accurate.

As network operators and consumers become more and more aware of the importance of the security of supply in electrical power systems, they are becoming increasingly interested in the continuous measurement of power quality. In order to identify problems at an early stage and to be able to take appropriate preventative measures, the first step is to use a suitable measuring system to closely analyse the supply system or technical equipment over a longer time period. Depending on the specific facility and application, the requirements to be met by a suitable measuring system are very varied and include a wide range of different measurement functions.

Formerly Borri, Power Control (PCL) has received a glowing review for its electrical expertise and high performance UPS solutions from one of the world’s largest travel sites.

Due to continued business expansion, the global travel review company recently replaced its 60kVA, end of life unit with the purchase of two Borri B8000FXS 20kVA UPS units, which are now handling added capacity the company’s newest facility.

Electrical Review is launching a new reader survey and the team would be very grateful if you could take five minutes of your time to complete it.

We hope to discover your views on the electrical sector, its drivers and challenges, how you see the future of your business, which events you value.

Most of all, we want to know what you would like to see in Electrical Review in the future, which sections of the magazine you are most likely to read and your views on our website, supplements and e-newsletters.

Security is mortal’s chiefest enemy

Is every single British electricity-generating company now employing cyber security experts?  I understand American power companies are now under constant, accelerating attack, either from on line troublemakers. Or (more often) from state-sponsored players like China and Iran.

An investigation by the magazine USA today found between 2011 and 2014, there were no less than 362 reports of physical and cyber attacks on electric utility companies. Indeed in 2013 alone some 161 cyber attacks on the energy sector were reported to the US Department of Homeland Security. That is five times higher than just a couple of years before.

The September issue of Electrical Review will feature a dedicated lighting supplement.

The supplement will cover topics including energy efficiency, LEDs, recycling, emergency lighting, building controls and, very importantly, legislation.

Don't miss the chance to access this information. The supplement will be available in print, as a digital issue and at www.electricalreview.co.uk. Please visit the website to register.

The energy and life-cycle benefits of LED lighting have been well documented but less attention has been paid to the opportunity they offer for utilising Power over Ethernet. Andrew Pease of Mackwell discusses these additional benefits

Electrical Review will next month publish its 2015 Specification Guide.

The Electrical Review Annual Specification Guide is a publication aimed at electrical engineers, project managers, consultants, and electrical contractors. This specialist companion title from Electrical Review is a print and online resource and best practice guide to specifying electrical systems in buildings and industry, from plugs and sockets right through to HV substation installation and smart grids.

When specifying LED lighting it is important to be aware of all of the factors that impact on the performance of the installation. Simon Miles of Carbon8lighting highlights the key issues

Anyone who has even a passing interest in lighting cannot have failed to notice the rapid emergence of LED lighting, that has now become the light source of choice for many commercial lighting applications. However, what is less known is the fact that the latest generation of LED modules, coupled with luminaires designed specifically, are now delivering sufficiently high light outputs for many other applications. As a result, LED luminaires can now be specified with confidence for high bay and exterior lighting.
