New supply chain videos simplify CPR message
The Approved Cables Initiative (ACI) has developed an online video campaign to highlight Construction Products Regulation (CPR) requirements and how they affect the cable industry. The campaign targets four audiences and complements a range of animated videos launched by the ACI earlier this year. Part of the ACI’s further involvement in content marketing, the four videos target contractors, wholesalers and distributors, speciﬁers and designers, and manufacturers spelling out each group’s speciﬁc responsibilities and what changes from 1 July. Peter Smeeth, of the Approved Cables Initiative said: “We are using this medium to support our existing communications activity. Our target audiences look more and more to online material to ﬁnd answers and there are a wide range of channels for sharing this information. The ACI has been concerned by the level of misinformation around CPR and to this end we have produced these videos to offer a succinct explanation of what is required. “It is also to remind those in the supply chain that the ACI will proactively police the market for non-compliant cable product and bring to the attention of relevant UK authorities all breaches of CPR Certiﬁcation and Approval. “Trading Standards will also make market checks and there are penalties for putting product on the market that is not CPR compliant.” The videos will be hosted on the ACI’s website and its YouTube channel and it is hoped that all cable industry associations will share the content with members and followers. The videos can be watched at www.aci.org.uk The ACI launched in 2010 to address the issues of unsafe, non-approved and sub-standard cables entering the UK market place.

Confusion over waste lamps Eucolight survey shows consumers struggle to identify different types of waste lamps EucoLight, the European Association for lighting WEEE compliance schemes, has conducted a multinational consumer survey. The survey concluded many consumers were unable to distinguish between different lamp types. The results reveal that citizens from the six countries surveyed were not sure how to distinguish between energy-saving, LED, incandescent and halogen lamps when shown images of the lamps. The ﬁndings were very similar in all the countries surveyed. In the case of energy-saving lamps, between 27% and 42% of respondents identiﬁed them correctly, as opposed to 18%-35% who confused them with LED bulbs. When asked to identify an LED lamp, only between 14% and 23% of
Electrical Review | July/August 2017
respondents classiﬁed it correctly, whereas between 31% and 45% thought it was an energy-saving light bulb. Recolight CEO Nigel Harvey, who is also a director of Eucolight said “These ﬁndings mirror the situation in the UK. Most consumers have difﬁculty in differentiating different lamp types. That is why it is logical for all waste lamps to be collected in the same container”.
RECYCLING AWARENESS VARIES WITH CONSUMERS ACROSS ALL COUNTRIES Respondents were also asked if they know where they should deposit lamps for recycling. Spanish and Belgian citizens scored highest, with around 50% suggesting local authority waste facilities or recycling plant, and more than 10% suggesting the retail
outlet where they purchase their lamps.
IMPACT OF THE FINDINGS The results of this survey conﬁrms the EucoLight position, that all types of lamps should be collected together in the same container. This would avoid the risk of consumer confusion between lamps leading to a decrease in recycling efﬁciency and a possible decline in the recycling rate. It also conﬁrms that it is appropriate for LED and other lamps to be recorded within the same category or subcategory under the WEEE directive. Nigel Harvey added: “We will continue to advise all our collection partners, both consumer and commercial that LEDs can be placed in the same container as ﬂuorescent lamps. At Recolight we collect all lighting in scope of the WEEE regulations.”

Electrical apprentice of the year announced George Maynard from Leicester has been named winner of the 2017 NICEIC and ELECSA Apprentice of the Year competition, sponsored by Scolmore Group. The 25-year-old was one of eight competitors to reach the Grand Final, which Scolmore was very proud to host at its headquarters on Tuesday 6 June. Maynard said: “I was shocked when they called my name out. I thought all the lads in the ﬁnal produced some great work and they were all top guys. I think getting to the ﬁnal was a great achievement to be honest. It’s a lovely way to
round off all the hard work I have put in over the last three years.” The ﬁnalists were put through a gruelling day of challenges comprising nine separate tasks designed to assess their abilities across a range of disciplines including testing, fault ﬁnding, conduit bending, tray manufacturing and safe isolation. This year’s ﬁnal challenge also included a Virtual Reality test followed by an interview with Certsure’s technical standards director, Alan Wells. As well as hosting the grand ﬁnale of the competition at the company’s head ofﬁce

GOSSAGE Undress, and get an internship Czech power generation conglomerate CEZ had 10 bikini-clad female high-school graduates pose for the TV cameras in a cooling tower of its 2,000-megawatt Temelin nuclear power plant. It was – I am glad to report – closed for maintenance at the time. It then asked Facebook users to vote for their favourite, with the most popular teenager winning a fourteen-day internship at the plant, itself based just 55 miles north-east of the anti-nuclear German state of Bavaria. The criteria for success did not apparently include any assessment of the competitors’ technical qualiﬁcations. In a press release CEZ likened the photoshoot to its previous cultural enrichment programmes, such as hosting the Bohemian Philharmonic at the plant in South Bohemia. The statement said the experience was greatly enjoyed by the girls, who were required to wear – in addition to their bikinis – hard hats and enclosed shoes at all times. “This competition is absolutely outside the bounds of ethics. In 2017, I ﬁnd it incredible that someone could gain a professional advantage for their good looks,” harrumphed Czech human rights lawyer Petra Havlíková. The power plant was not the ﬁrst to link the wonders of nuclear energy with the revealing bathing suit. Russia used to host an annual beauty contest open to women working in nuclear industries or studying in nuclear-related subjects in Russia and former USSR countries. Women aged 18 to 45 would pose in front of a nuclear power plant. For that matter, the French inventor of the bikini named it after the Paciﬁc nuclear test site Bikini Atoll, in the hopes that it would create an “explosive commercial and cultural reaction” like the newly-developed atom bomb.
UK AEA not OK AEA There may still be a few who naively think that nuclear scientists have their feet solidly on terra ﬁrma. Deal with solid facts not outlandish claims are not given to political hyperbole, but it seems this is now far from the case should they be promoted to the higher echelons of the UK Atomic Energy Authority (UKAEA). First example: Professor Roger Cashmore the present UKAEA chair. When discussing the possibility of the UK ceasing remaining a full Euratom member after Brexit, Cashmore told a press conference that, if so, by 2025 “you could be doing your writing by candlelight on a typewriter”. The inference presumably being that, if some older nuclear plants had to close prematurely, there will be no electricity available any more. This is total nonsense. In fact, nuclear now provides just 20% of current electricity. With overall sales of electricity having already dropped 16% over the past decade, the lights won’t be going out at all. Second example: Professor Ian Chapman, present CEO of UKAEA. Subject to the EU extending the UK’s contract to host beyond 2018, the UK government has agreed to continue underwriting its “fair share” of JET – the Joint European Torus project ‘s running costs, which is based at the Culham Centre for Fusion Energy in Oxfordshire. Chapman has welcomed this with these effusive words: “UKAEA are pleased that the UK Government is committed to exploiting JET, as we prepare to break fusion records in the next few years.” Bearing in mind that, after over ﬁfty years of taxpayer funded research, there is still no sign of a single productive kilowatt-hour emerging from nuclear fusion research, it is surely absurd to claim there are as yet any records to break.
Lost in translation Insecure passwords used by managers at nuclear power plants have been found in two lists of stolen credentials being traded on Russian hacking sites. Employees of Electricité de France (EDF) Energy, which operates the UK’s 15 civil nuclear reactors, used the passwords “Nuclear1” and “Rad1at10n”, most likely to sign up to the business networking site LinkedIn. They hold senior positions at nuclear plants. The passwords are insecure because they are based on easily guessable words relating directly to the employees’ jobs. The lists of credentials were put together from hacks of social media and other sites over the past decade, and were traded privately before being made public. It has been revealed that, as well as EDF nuclear bosses, they contained passwords of cabinet ministers, ambassadors and senior police ofﬁcers. Security experts warned that if the passwords had been re-used they could be exploited to compromise government accounts, or to blackmail ofﬁcials using material from private email or social media accounts. EDF refused to comment on the leaked passwords but retorted that the company was “continually reviewing its defences and preparedness in this area”. The ﬁndings come as a conﬂict emerged between guidance from the National Cyber Security Centre (NCSC), the government’s top information security agency, and password policies used by the UK Atomic Energy Authority and the Ofﬁce for Nuclear Regulation, plus the Houses of Parliament, the Metropolitan Police and the National Crime Agency. All ﬁve organisations require users to change passwords regularly. Meanwhile in America, hackers have succeeded in brieﬂy closing down the Wolf Creek nuclear power station in Kansas. Energy Secretary Rick Perry describes the perpetrators as “state sponsored.”
Back to the future Yet another delay regarding the ﬁnal demise of Gaz and Leccy, those intensely irritating cartoon prototypes for the 53 million smart meters supposed to be installed in every household and small business. I have long mused about the obsolescence already of many of these so-called “smart” meters, rendering the entire £14bn exercise of very limited beneﬁt to users. I am indebted to Jon Ferris of Utilitywise for reminding me that when the regulator OFGEM approved the detail of the smart meter design-phase back in 2011, it was the iPhone3 that was the mobile phone of choice. If that original nine-year programme was like offering consumers a Nokia 1100 at the time of the iPhone3, extending its completion deadline to 2005 is the effective equivalent of returning to the days before text messaging. Truly much ado about very little. Electrical Review | July/August 2017

How UPS efficiency can contribute to data centre PUE Alan Luscombe, director at Uninterruptible Power Supplies Ltd, D .RKOHU FRPSDQ\ ORRNV DW WKH VLJQLĂ&#x20AC; FDQFH RI 3RZHU 8VDJH (IIHFWLYHQHVV 38( IRU GDWDFHQWUHV DQG DW KRZ PRGHUQ HIĂ&#x20AC; FLHQW UPS design can contribute to this metric.
s data centre size, energy costs and green legislation demands increase, so does the pressure to improve efďŹ ciency in data centres. One popular metric for checking this is Power Usage Effectiveness, or PUE, which was ďŹ rst introduced in 2006 and then promoted by the Green Grid in 2007. PUE compares a data centreâ&#x20AC;&#x2122;s total electrical energy consumption â&#x20AC;&#x201C; when power conversion, cooling, lighting and other overheads are accounted for â&#x20AC;&#x201C; with the amount taken by the ICT equipment performing useful data processing and communications tasks. It is expressed as:
Total datacentre energy ICT equipment energy
This means that an ideal data centre would have a PUE of 1, where all incoming energy is consumed by useful computing tasks. While real facilities cannot attain this value, they have been approaching it steadily over recent years. Googleâ&#x20AC;&#x2122;s entire ďŹ&#x201A;eet of data centres has achieved a comprehensive trailing 12-month PUE of 1.12 for all seasons,
including all sources of overhead. There are limitations to be considered when applying PUE or comparing data centres. For example, data centres around the world are subject to widely varying climactic conditions. A facility in a hot country will have a large cooling load compared with an identical installation in a more temperate zone. This is signiďŹ cant, as cooling can account for up to 30% of a facilityâ&#x20AC;&#x2122;s power. Loading on the data centreâ&#x20AC;&#x2122;s servers is also a factor, as server utilisation levels affect efďŹ ciency.
UPSS AND PUE In Googleâ&#x20AC;&#x2122;s PUE calculations, as well as those of most other operators, the UPS installation is considered as part of the infrastructure overhead; therefore, improving its efficiency will reduce PUE. Accordingly, letâ&#x20AC;&#x2122;s look at the UPS efficiency options available to data centre operators. The first step is to review your UPS installation, as it may have some surprises. It could be older than you think, and possibly using transformerbased technology rather than the
transformerless approach that has now replaced it. This has significant energy implications, as eliminating the transformer increases UPS efficiency by around five percent, and possibly more if the UPS is only partially loaded â&#x20AC;&#x201C; see Fig.1. Further savings arise as increasing the UPSâ&#x20AC;&#x2122;s efficiency also reduces the cooling load. Note that the transformerless UPS efďŹ ciency curve remains relatively ďŹ&#x201A;at over the entire load range. This means that even in a â&#x20AC;&#x2DC;1+1â&#x20AC;&#x2122; redundant system, where no UPS is more than 50% loaded, efďŹ ciency remains high. Some modular UPS systems also offer a smart operating mode â&#x20AC;&#x201C; known as the Xtra VFI mode on UPS Ltdâ&#x20AC;&#x2122;s PowerWAVE 9500 DPA â&#x20AC;&#x201C; which automatically switches excess modules to standby if the load drops. They remain on standby and ready to resume active operation immediately if the load recovers or the mains fails. This measure is especially effective for loads of less than 25 percent of full capacity. Another possibility, suitable for some but certainly not all installations, is to run the UPS in Eco mode. Power from the incoming mains supply bypasses the UPS conversion stages to feed the load directly by default, only routing through these stages if power problems arise. Eliminating power conversion losses allows UPS efďŹ ciency of up to 99% to be achieved, but loads are exposed to any mains-borne spikes or other problems during normal operation.

The next generation: Human centric lighting (HCL) Human comfort is affected by thermal factors; physical factors and personal factors. Another factor that can affect human comfort is the visual of the room and its light intensity. Paul Jones of BEG explains
ccording to research, exposure to natural daylight can increase productivity, reduce stress and improve sleep and circadian rhythms which improves the overall health and wellbeing of individuals in the workplace. Exposure to natural sunlight is also thought to increase the brain’s release of the hormone serotonin. This is associated with boosting mood and helping a person feel calm and focused. Scientists identiﬁed a third light receptor in addition to rods (twilight vision) and cones (colour vision) back in 2002. These cells are both photosensitive, meaning that they respond to light, but are also non-visual; they only react on
The next generation of human centric lighting the ambient brightness and regulate your body clock as a result. Artiﬁcial lighting, therefore, has a huge role to play in assisting the body clock with determining what time of day it is and ultimately in stabilising our biological rhythms. Human Centric Lighting has a lot of buzz surrounding it, at the moment, as manufacturers work towards providing a number of solutions for the public and private sectors. In the UK, we are noticing a huge interest from facilities managers who have begun to explore smart lighting to maximise the use of natural daylight to enhance the vision, well-being and performance of its employees in the workplace. There is evidence that in learning spaces, in particular, being able to programme in or Electrical Review | July/August 2017
control a lighting scheme instantly impacts the classroom environment so this is very relevant for the education sector too for use in schools, colleges and universities. For example, exposure to bright natural light in the morning reduces sleepiness and increases alertness. Alternatively, having the ability to dim the lighting in a learning space, will create a more calming atmosphere. At BEG, we are the ﬁrst in the industry to develop a wellness multi-sensor that controls the lighting based on time, presence and circadian rhythm with its ‘tuneable white function’. It works by adjusting the colour temperature over a 24-hour period from warm white to daylight white and the illumination intensity from 500 to 1500 lux. The dimming of the individual lights is continuous and harmonious so that
the change is not directly visible. This signiﬁcantly improves the quality of the artiﬁcial light, mimicking the daylight and improving well-being and health. Energy consumption is also optimised. At the lower end of the scale, from 2000K to 3000K, the light produced is called ‘warm white’ and ranges from orange to yellowwhite in appearance. Color temperatures between 3100K and 4500K are referred to as ‘cool white’ or ‘bright white’. Lighting manufacturers use daylight as the benchmark to which to compare colour rendering of electric lights and we use an index called the CRI or colour rendering index as a quantitative measure of the ability of a light source to show the colours of various objects accurately, when compared with a natural light source. Using these measures and combining them with research, the lighting industry is completely transforming workplaces. This latest generation of smart lighting is allowing facilities managers to maximise the comfort and performance of their employees down to a task by task basis. For example, rather than one type of lighting being used across an entire ofﬁce, control panels can now be used to select lighting quality based on various types of activity or the age of employees taking part (research has shown that the older you are, the more light you need). Research papers continue to be released with compelling results showing how biological beneﬁts such as alertness, cognitive performance, and good sleepwake cycles are all being affected positively. Even emotional beneﬁts such as improved mood are being recorded, so there will be much more noise around Human Centric Lighting to come. We hope everyone in the industry continues to push the boundaries of innovation and discovery to bring even more new technologies to the forefront.

How to Reduce Costs When Installing Enclosures By Paul Metcalfe, Rittal’s Product Manager for Enclosures
itting out the interior of an enclosure creates a number of challenges for switchgear manufacturers. First, there are the high packing densities of the enclosure’s many components and second, there are typically very short project times. The internal components in question include power distribution systems, switchgear, automation components, clamps etc, and their requisite cabling. Placing all this logically inside the enclosure is both an art and a science! Engineers need to create an easy to follow solution for end users, as well as pay attention to relevant standards and follow the component manufacturers’ installation instructions. Of course, the more time it takes to conﬁgure the interior, the greater the cost pressures on the electrical engineering company – particularly when multiplied across many projects.
Electrical Review | ?????? 2016
ENCLOSURE DESIGN The design of the actual enclosure and the amount of space it offers has a major part to play in how quickly the interior can be ﬁtted out. Rittal’s TS 8 enclosure has a central element, a frame section with a uniform 25-mm pitch pattern which adds to the ﬂexibility of the space for electrical equipment and also reduces “wasted space” to a minimum. Two other mounting levels can be used and, by using the external mounting level, the installer can achieve up to 15 per cent more available space, compared with a single-level alternative.
TAKE FULL ADVANTAGE OF THE GAPS The gaps between the bayed enclosures can also be utilised to create more space. By inserting a mounting plate inﬁll between two TS 8 bayed enclosures, installers can create a continuous mounting plate.
RITTAL | 17
Alternatively, this space could be useful for a cable duct. Installers can then add other components onto the mounting plate. All these ideas can solve any problems of packing densities in the enclosure.
WELL THOUGHT-OUT INSTALLATION CONCEPTS SAVE TIME A faster installation has a number of advantages; apart from the obvious fact that clients will be happier, fewer staff are also needed, which lowers costs. Many systems still require two people to install them (for example, to mount the side panel of the enclosure) so choosing an enclosure that only needs one installer has considerable business beneﬁts. Again, the TS 8 is constructed so the side panel can ﬁrst be suspended from the enclosure. It then remains in position without having to be held by a second person before it is screwed tight. Other assembly steps (for example, changing the door hinges from one side to the other) follow the same principle so there is no need for two installers. Meanwhile, the TS 8’s Flex-Block base, means there is no need for tools - panels can be simply clipped on. The entire base has been assembled in less than 60 seconds during installation workshops.
GO ONLINE FOR THE PERFECT CONFIGURATION At a time when products and systems are
becoming increasingly complex, conﬁgurators are an indispensable tool for helping customers quickly track down the right product for their needs. These online tools help users precisely determine the necessary parameters, quickly select the appropriate solution, and automatically compile technical data. For example, Rittal’s TopTherm chiller conﬁgurator enables designers and technical buyers in to put together machinery and process cooling systems. It provides precise estimations of the required cooling output, rapid identiﬁcation of the most suitable solution and automatic generation of all technical speciﬁcations.
straps of copper wire connected to the frames, the side panels, the enclosure roof, any other panels as well as the door. Once ﬁtted, the straps ensure there is an equalisation of potential and the enclosure components can be earthed via the protective conductor of the voltage supply. These straps have to be attached by hand during enclosure assembly; unfortunately, should a strap be inadvertently forgotten, the ﬁnished switchgear will still be able to function despite the risks it poses in the event of a fault. The obvious step for the industry is moving towards built-in safety, avoiding the need necessarily having to earth each
SAFETY IS A PRIME CONSIDERATION
individual panel. The TS 8’s, side panels, enclosure roof, rear panel and gland plates are all automatically connected to the frame conductively, creating potential equalisation. The enclosure uses special claws or washers which press through the electrically non-conductive surface coating of the panels during assembly to achieve a reliable contact. The earthing strap then only needs to be attached to the enclosure door – although obviously the ﬁnal decision as to whether or not to attach additional straps is left with the user. The contact resistance between the panels and the enclosure frame is less than 0.1 Ω, the value demanded by the DIN EN 62208 empty enclosures standard.
Finally, the number one priority for this – and any other electrical engineering installation – is, of course, safety. Clearly fault currents (short circuits) and enclosures which become “live” both have the potential to cause serious harm. The earthing of metallic parts on electrical systems is prescribed virtually everywhere and applies to all electrical equipment and units – from simple lamps to low voltage distribution systems. In low voltage switchgear, all the metal frame and enclosure parts at risk of stray voltage have to be earthed. Many enclosure manufacturers require each panel to be earthed through earthing

PROBLEM At Winarâ&#x20AC;&#x2122;s previous facility, traditional pipe and wire was used for its electrical distribution needs. This meant that the company was forced to rearrange production around the electrical infrastructure, as opposed to arranging it for optimal efďŹ ciency. As the company began to evolve and take on a heavier manufacturing role, it was faced with multiple electrical constraints. The addition of state-of-the-art equipment posed many challenges; including having to decide where to place the equipment, and then waiting for an electrician to come hard wire it in place. â&#x20AC;&#x153;I remember the ďŹ rst time we bought a new crimping machine and I had to hire an electrician to come in. We wired it in and it was only there for about 3 months before we moved it to the other end of the building,â&#x20AC;? said Jeffrey Rees, COO of Winar Connection. â&#x20AC;&#x153;It was frustrating. Once you hard pipe something there itâ&#x20AC;&#x2122;s almost like a castle. Itâ&#x20AC;&#x2122;s immovableâ&#x20AC;&#x201D;itâ&#x20AC;&#x2122;s stuck there.â&#x20AC;? Having to call in an electrician for any electrical change was a Electrical Review | July/August 2017
signiďŹ cant drain on both money and time for Winar. The simple task of relocating a work station was a six to eight week process with the companyâ&#x20AC;&#x2122;s current rigid conduit system. This electrical distribution method also required the company to know exactly where they would like a new piece of equipment to be located at the time of purchase. Often times, only a short while later Winar would have to move this new piece of equipment, requiring an electrician to again come to the facility- resulting in extra costs and wasteful downtime. To successfully change as a company, the ability to seamlessly add new equipment and rearrange production ďŹ&#x201A;ow is necessary. In Winarâ&#x20AC;&#x2122;s case, dealing with continuous electrical constraints was suffocating the companyâ&#x20AC;&#x2122;s growth potential.
SOLUTION After making the decision to build a new building in 2014, Winar knew they had to ďŹ nd a solution to avoid the electrical ďŹ&#x201A;exibility constraints it had experienced in its old building. Winar chose

On a Saturday we were able to take down a work station, move it, and be back up and running on Monday. If we had a rigid conduit system, that would have been a six to eight week process Jeffrey Rees, COO Winar Connection “We were able to move the Starline bus product ourselves and set up the power ourselves in the exact locations that we needed it without having other people in our facility, or product lines being shut down,” said Shawn Conway, Senior Account Manager at Winar Connection. “So it was a very easy, very versatile, very portable product to use.” Using Starline, the same workstation rearrangement that used to take six to eight weeks is reduced to a day. In addition, in the past the best way to move hard wired equipment from point A to point B was to use extension cords. The issue with draping multiple extension cords across a production ﬂoor is that it becomes a signiﬁcant safety hazard. With Starline, Winar can simply disconnect a plug-in unit, safely move it to the location where power is needed and have equipment ready to go within 15 minutes.
RESULT By choosing Starline Track Busway for its power distribution, Winar Connection ensured its access to power would never be a hindrance on the company’s future evolution. “Our business changes so fast, that we have to have the ﬂexibility for the future,” said Jeff. “I knew it was an investment in our future, and that was the biggest thing.” Not only is Winar now poised and ready for future changes, but it can rest assured that costs associated with electrical reconﬁguration will be signiﬁcantly reduced. Jeff continued, “I know every day there’s savings with Starline. I very much would recommend Starline Track Busway to other companies for its cost savings, its ﬂexibility and its ease of use.”
ABOUT UNIVERSAL ELECTRIC CORPORATION Universal Electric Corporation (UEC), the manufacturer of Starline, is a global leader in power distribution equipment.

own network and through the cloud. It basically allows us to monitor event logs, history logs of a UPS, so we know straight away if there is a problem with the UPS or if there is a minor problem, like an over temperature. It’s a very good way of up-monitoring the UPS, so we’ll know – probably before the customer knows – there’s a problem. Meaning we can respond very, very quickly and resolve the issue with the UPS. It could be a client action that is perfectly legitimate, we would contact the client immediately and say we have a problem here. If the client has a problem they don’t need to alert us, we’ll alert them, so we’re managing the equipment on their behalf. It also gives them remote access to their UPS (s) as you can have as many on the system as you want. They can go online and see the state of their UPS systems over their whole estate. The service is not limited to products under warranty, it can be applied to any Riello UPS.
A UPS maintenance plan provides a guaranteed time response rather than best endeavours. Maintenance plan customers have priority call on service resources. Riello UPS provides three types of maintenance plan: - Silver - 12 working hour response - Gold - 8 working hour response - Platinum - same day within 4 clock hours Maintenance plans can be taken out for in-warranty and outside warranty systems, and for both Riello UPS and third party products. There are many features to each maintenance plan.

Inspect and protect Atlas launched its Inspect and Protect Campaign to raise quality standards for the testing and inspection of lightning protection systems, aware that there are an increasing number of companies ZKR DUH QRW TXDOLÀHG RU FRPSHWHQW WR undertake this specialist work.
recommends that clients use the services of a specialist contractor which has the knowledge and skills to test and inspect the system in line with its design and installation. Additional testing will also be required to the lightning protection system after any building remedial works have taken place.
ATLAS INSPECT & PROTECT CAMPAIGN
WHAT IS A CRITICAL STRUCTURE?
Establish clear standards of compentency
ith over 300,000 lightning strikes in the UK every year, organisations should have a lightning protection system installed to protect their building, its occupants and contents from potential damage in the event of a strike. The majority of buildings will be termed a ‘critical structure’ as deﬁned in the recognised British Standard for the design, installation and testing of lightning protection systems and will require an annual test and inspection programme undertaken by a competent Specialist Contractor to ensure their continued safety.
A critical structure is deﬁned as one which contains sensitive internal systems including ofﬁce blocks; commercial buildings or places where a high number of people may be present, such as churches or heritage buildings; and buildings where explosive materials are stored. Buildings which are classed as ‘critical’ should have their lightning protection system visually inspected every six months with electrical testing performed once a year.
ANNUAL TESTING Electrical testing should be undertaken every year by a competent person who has the training and experience of working within the lightning protection industry. ATLAS Electrical Review | July/August 2017
Inspect and Protect has two objectives: • Establish clear standards of competency for testing and inspection work. • This includes promoting the right formal qualiﬁcations and ensuring clients use reputable companies with a track record of lightning protection work which will provide a formal outline of the work to be undertaken. • Encourage clients to specify ATLAS members for testing and inspection work
To help you to identify an experienced lightning protection professional, ATLAS has developed the handy leaﬂet ‘Choosing a Specialist Contractor for your Lightning Protection System’ outlining the skills and experience that you should look for when choosing your specialist contractor. Use this in conjunction with the ‘Client Checklist for Lightning Protection Systems’ to ensure that the specialist contractor provides a thorough inspection of your system in line with the current British Standard.

DEHN protects Safety Critical Systems Ensure reliable operation of your safety systems
e it ﬁre protection, alarm and security systems or emergency and escape route lighting, electrical safety systems are only safe if they are not susceptible to failure during thunderstorms or electrical surges. If lightning strikes or surges destroy safety systems / safety-related functions and are no longer available, then human life may be at risk. Surges can also lead to false alarms, inconvenience for operators, disruption to production and high follow-up and repair costs. Integrating safety systems into the lightning and surge protection design will protect them against damaging lightning strike and surges.
LIGHTNING PROTECTION ZONES IN BUILDINGS EQUIPPED WITH SAFETY SYSTEMS Safety systems, building management, telecommunication and control systems are increasingly used in all areas of residential, commercial and industrial buildings. These networked systems make the building intelligent and ensure its optimised use with building owners and operators making high demands on the availability and reliability of these systems. An external lightning protection system protects persons and material assets in a building from ﬁre, however, electrical and electronic systems are not protected against failure as a result of surges caused by a lightning discharge. The British Standard for lightning protection, BSEN62305, shows that automated ﬁre alarm systems should be protected against overvoltages if they have been selected as a risk component to reduce the level of tolerable risk during a risk assessment. A lightning protection zone concept in accordance with the BSEN 62305-4 Lightning Protection standard provides effective protection against surges caused by a lightning electromagnetic impulse (LEMP). According to this principle, the structure to be protected must be subdivided into inner lightning protection zones with different LEMP threat values. It is advisable to match the lightning protection zones and their LEMP threat values with the withstand capability of the relevant electronic system.
SURGE PROTECTION FOR SAFETY, SECURITY AND FIRE ALARM SYSTEMS Security, safety and alarm systems are all susceptible to surges, lightning discharges and over-voltages which can cause major problems to equipment resulting in physical damage and loss of service. The new DEHNvario DVR 2 BY S 150FM (928430) combined Type 1 Lightning current and surge arrester from DEHN protects electroacoustic systems – e.g. voice alarm, Public Address and loudspeaker systems from damaging lightning effects and surges. The performance parameters of the arrester and its high nominal current ensures safe operation of electroacoustic systems even during thunderstorms. The DEHNvario DVR 2 BY S 150 FM protects one cable pair and allows direct or indirect shield earthing. The plug-in design enables fast installation without tools and also has an integrated remote signalling contact. Easy replacement of the arrester is ensured by the integrated terminal unit which can be released and then removed from the enclosure. This new arrester is the ﬁrst device of the new DEHNvario product series. This series is a new product platform which provides the ﬂexibility to create different types of DEHNvario devices for a variety of applications from a common platform.
POWER SUPPLIES The d.c. supplies of emergency lighting systems and the a.c. supplies of ﬁre, security and burglar alarm systems also place especially high demands on surge protective devices. The DEHN Red/Line range of SPD’s with their high discharge capacity and low voltage protection levels meet these demands. Remote monitoring is also available via volt free contacts allowing the status of the SPD to be constantly monitored and integrated into the building management system.
The above illustration shows the lightning protection zones concept applied to a ﬁre alarm system

Big data, big responsibility Stewart Langdown, business development director at Mackwell discusses the challenges we face with big data and the opportunities that lie ahead
We at Mackwell have our own in-house software teams that write all our software, embedded or as part of our N-Light management system. We build security in and use a smart handshake to ensure our modules work together and deliver the results our customer and our customer’s customer demands. The data we generate is all about compliance and safety and you should ask yourself, do I want to take that risk of not dealing with data this way I previously mentioned Big Data equals Big Responsibility and this is very much the case. Where we create a basic function and use data to monitor and support a safety system, we see the positives and we applaud the beneﬁts of what technology brings. However, technology doesn’t diminish our responsibility.
DATA IS KNOWLEDGE
ince the launch of the world-wide web to the wider public on 6 August 1991 we started on a journey of creating the ﬁrst on line storage of data. Albeit this data was a few bytes stored on a PC somewhere on a remote server. Computers of course have been with us for many years with the ﬁrst commercial computers being available in the 1950’s so we have been digitising data for over 60 years. However, it’s the on-line storage and presence that I want to discuss and how we can relate this to the real world so far as buildings are concerned. I’m not interested in the Peta bytes of data uploaded to Facebook and YouTube each day but the useful data that tells us how much energy we are using, how the space is being used and of interest to Mackwell, whether your emergency lighting is safe and compliant.
We cannot hide from our browser history and we certainly can’t hide from our responsibilities but that’s a positive. We will be tracked, in fact we already are being tracked; our mobile phones, store loyalty cards, credit cards and Oyster cards are ways in which our lives are laid out before us in a complex spider’s web that has a series of regular patterns. We travel to work, we use the train, the underground, we buy a coffee and the paper. We swipe an access card to enter a building and we continually browse the web or stream content to our phones. Ultimately, we are creatures of habit and we like the security and familiarity of routine. If we can learn how an individual or group of people travel through or interact with a space then technology can achieve some remarkable things. It can predict our needs by learning from history and it can prepare areas for when we enter them. It can link disparate technology and allow it to work on one platform; one that we are familiar with – the screen of our mobile device. We then have a choice. Do we use the interface of our connected life to further connect to the very fabric of the world or space in which we occupy, knowing that data will be generated and potentially used to manage us? How conﬁdent are we now in our ability to manage services and technology? Do we need to?
DATA IS RESPONSIBILITY
DATA IS OPPORTUNITY
Data is information and information can be useful, but let’s not kid ourselves, data for data’s sake achieves nothing if you’re not going to act on that information. An alarm is triggered and a fault found. How is this fault reviewed? What procedures do you have in place to address that challenge and how do you provide an audit trail to conﬁrm you’ve acted? Data, means that if you record it then you have no excuse if you don’t act. So, you could sum this up as Big Data, big responsibility. So being responsible, how do you manage your data and ensure that data is secure? I forgot to mention the added challenge of security; how do we ensure that our data can’t be hacked or that the product we are buying doesn’t have an engineering re-set code 1111? It’s the single biggest challenge to the Internet of Things (IoT). The key is software, who writes it and who owns it.
If we embrace technology and what data can do, especially the rather weight sensitive but aptly named Big Data then it’s like having the world’s greatest library at your ﬁngertips. Use it and grow or ignore it and never evolve. So many people talk about technology but the proof as they say is in the proving; education is key. The challenge for all industries is that this is a new branch of business/ commerce; it’s a service based solution where our data can improve the quality of our lives. That said, this can only ever happen if the right infrastructure is in place and we use that data properly. Data can make our lives safer, smarter and ultimately more enjoyable, if used correctly. Ignore Big Data and nothing major will happen, the sky certainly won’t fall in. Embrace information and suddenly you’re on a journey to improve your lit environment and enhance your journey through our business and social lives. So Big data, big responsibility, even bigger opportunity.

ith exchange facilities in every major UK city, featuring hundreds of high voltage cables, each containing an estimated two to three thousand wires, the potential for damage, faults, or the outbreak of ďŹ re, is clear.Â A number of high-proďŹ le cases are easy to ďŹ nd through a quick online search, including the tens of thousands impacted when the Derby telephone exchange caught ďŹ re in late 2014. Fortunately, the early morning outbreak meant that there was no loss of life, although substantial costs to refurbish the facility and to re-establish services to 32,000 local homes and 4,000 businesses were incurred. The threat of ďŹ re is always present in environments where a large amount of cabling is in constant use, with telephone exchanges being at particular risk due to the heat of computer equipment being operated nearby and the fact that many cable management solutions in these facilities are outdated.Â Cable ďŹ res can start for a number of reasons, but an ever growing threat, especially in underground environments, comes from rodents. A chewed cable can easily impact the effectiveness of the wiring and, at worst, generate electrical short circuits and sparks that can ignite. Many telephone exchanges are located within enclosed environments that are also the natural habitat of mice and rats. The Manchester exchange for instance, is situated 115ft underground, making the proximity of rodents unavoidable.
THE SOLUTION Preventing the ingress of dust and liquids, through conduit and ďŹ ttings that are Ingress Protection (IP) rated, is also a key consideration. The impact of foreign bodies making contact with internal wiring could be another cause of electrical faults and ďŹ res, whilst water damage can cause loss of connection for landlines, as seen at the start of this year in Chester.Â Taking all of these risks into account, a solid and reliable solution must now be applied; arguably to all telephone exchanges in the country. An infrastructure upgrade not only protects life and ďŹ nances, but meets the on-going demand for broadband with continued advances in ďŹ bre cabling that will allow the handling of more data than ever before. With each major city having its own telephone exchange, ensuring complete protection is a large scale operation.

programme of upgrades at the exchanges of a major UK telecoms provider, where a number of quick and effective solutions are being installed over the next three to ﬁve years. The major change is to introduce new systems that prioritise the use of enclosed wiring looms. A key area of the upgrade naturally related to ﬁre safety, where a UL94 V-0 ﬁre rating was speciﬁed for the equipment we provided. Additionally, with the large amount of exchanges that need upgrading across the country, efﬁciency of installation was also something we needed to address. Using the speciﬁcation and other criteria, we decided upon a combination of our non-metallic PRCS conduit and Adaptalok ATS™ ﬁttings, speciﬁcally the blue elastomer version as it achieves the V0 ﬁre rating. We’ve seen a positive response to our Adaptalok ATS™ non-metallic ﬁttings due to the particular environmental constraints of a telephone exchange. For

example, it has a simple ‘push to lock’ action which makes it easy to use in the tight and often dark workspaces found in telephone exchanges, particularly when they are located underground. Again paying attention to the particular enviornmental constraints of an exchange, the PRCS conduit was an ideal choice because of its suitability for use in conﬁned areas, due to its Enhanced Low Fire Hazard (LFH), self-extinguishing, low smoke and zero halogen properties, as well as its good compression and tensile strength. As access to these types of cables is often limited, in-situ checks are unlikely and monitoring of the strong threat of exposure to dirt and water could be limited. As a result, ingress protection is vital and as mentioned is something that was a key consideration for exchanges and for us in providing a solution. Together the PRCS conduit with ATS ﬁttings are able to provide an IP rating up
Electrical Review | July/August 2017
to IP69K. As a complete non-metallic solution, there is inherent resistance from corrosion, which helps reduce the risk of failure and can provide savings in the cost of maintenance. Ultimately, changing to an internet cloud-based service, where information is stored remotely, may remove the need for outdated telephone exchanges that are situated across multiple locations. However, this would be an expensive operation which despite removing the need for wire routing, would still have its own requirements for protection via conduit and ﬁttings. The best solution at present is to maximise the use of effective and compliant conduit and ﬁttings that are readily available on the market.

S EN 54-23 stipulates the requirements, test methods and performance criteria for Visual Alarm Devices in ďŹ re detection and ďŹ re alarm systems. In order to comply, manufacturers now need to present their productsâ&#x20AC;&#x2122; performance data in a uniform manner so that they can be directly compared and their suitability assessed for particular applications. EN54-23 gives an independent assessment of a beaconâ&#x20AC;&#x2122;s performance in the same way that EN53-3 does for sounders. With this standard, systems designers, risk assessors and installers can assess what the requirement of a beacon must be in order to deal with a particular application and then have conďŹ dence in choosing the right device for the job. For example, compliant beacons and sounder beacons are designed for areas where people with hearing difďŹ culties may be alone, environments with high levels of ambient noise, and areas with restricted access. The development of EN54-23 required a fundamental change in visible alarm technology to ensure that the light output from warning beacons is sufďŹ ciently bright to attract attention. EN 54-23 allows for three product classiďŹ cations: W (wall); C (ceiling); and O (open). The key performance indicators are that the output of the device must be greater than one candela (cd) and less than 500 cd; the ďŹ&#x201A;ash rate must be between 0.5 and 2.0Hz. The critical requirement from a manufacturerâ&#x20AC;&#x2122;s point of view is that each model must be tested to demonstrate compliance with the standardâ&#x20AC;&#x2122;s requirements. For ceiling-mounted devices, the manufacturer must deďŹ ne the maximum height at which it can be installed, set by the standard 3, 6, or 9 metres. A wallmounted device must be installed at a minimum of 2.4m from the ďŹ&#x201A;oor in the same way a sounder is today. The coverage volume, deďŹ ned by the manufacturer, is that in which the output meets the minimum illumination requirement of 0.4 lumens/m2 (lux) on a perpendicular surface. To avoid having to install an unacceptably large number of beacons, manufacturers are typically designing to meet smoke detector spacings. The result is that W class devices are assessed in terms of the dimensions of the cube of light they cover and C devices are assessed as the diameter of a cylinder of light. The coverage of an O class device is a cuboid of light, deďŹ ned by the manufacturer as independent of the EN54-23 height/ placement requirements. A further important consideration is if the risk assessment does
Electrical Review | July/August 2017
not specify a VAD for a particular area, it will still be acceptable to install a non-compliant beacon as a supplementary indicator to a sounder.
RED OR WHITE FLASH? The ďŹ re industry has traditionally used a red ďŹ&#x201A;ash to denote an alarm condition. This presented a challenge under EN 54-23, as the light intensity drops as it is ďŹ ltered through a red lens, requiring more power to achieve the required coverage. This loss can be as much as 80%. Installers and speciďŹ ers need to be aware of this when selecting a VAD. If an existing installation has VADs with red ďŹ&#x201A;ash then the colour of the ďŹ&#x201A;ash has to remain the same on any replacements or extensions to the system.
SPECIFYING When selecting a beacon, room coverage, ďŹ&#x201A;ash colour and current consumption are the key measures. The milliamp per metre speciďŹ cation of a product offers a good guide to selecting the most efďŹ cient VAD possible. The introduction of EN 54-23 has led to growth in the use of VADs and this is set to continue. They offer the reassurance of a visual indication to a ďŹ re alarm and help to mitigate the risk to the building occupants. Fully automated and highly reliable, used as part of a comprehensive ďŹ re detection system, VADs remove any human error associated with systems that rely on human interaction or the requirement to ensure that portable tactile devices are working and that the batteries are charged. The standard enforces a speciďŹ c illumination level, ensuring that any visual alarm is meaningful and inclusive to all.

These products switch lights on when an area is occupied and maintain a chosen lux level by dimming the lights in response to changes in the ambient daylight level. There is also a ‘run-on’ timer (corridor function) which allows the light to return to a minimum background level following a period of occupancy. This can either be for a chosen time or as a permanent background light. Each control has a switching relay, capable of switching 2 amps (500W) LED lamps and ﬁttings or up to 6 amps (1500W) of most other types of load.

Flexibility and ease of installation were the major considerations in the design of the Inceptor Omni and key features are an adjustable colour temperature switch allowing the selection of colour temperatures to suit the installation; interchangeable ﬁxed and adjustable bezels; and an insulation support clip for use when insulation is present. It is this combination of features that Scolmore believes will position Inceptor Omni as unique in the marketplace.
