ETI TO ANALYSE PERFORMANCEOF ENERGY INFRASTRUCTUREThe Energy Technologies Institute

(ETI) is to carry out a comprehensive

review of the costs and performance

of four key types of energy

infrastructure across the whole of

the UK.

The project will produce data for

electricity, gas, hydrogen and heat

and will look at transmission,

distribution, storage, conversions and

connections between now and 2050.

It will also examine the cost

differences within 12 different

onshore regions (East, East Midlands,

London, North East, North West,

Northern Ireland, Scotland, South East,

South West, Wales, West Midlands and

Yorkshire & Humber) as well as nine

offshore regions for transmission

(Channel Islands, Dogger Bank, East

Scotland, Hebrides, Irish Sea, Lundy,

Norfolk, Pentland, Shetlands) and two

regions for offshore storage (North

Sea and Humber).

A request for proposals (RfP) has

been issued for organisations

wanting to get involved in the project

and more details are available at

http://www.energytechnologies.co.uk.

The deadline for the notification of

intention to submit a proposal is 14

June and all proposals must be

received by 12 July.

The deadline for the notification of

intention to submit a proposal is 14

June and all proposals must be

received by 12 July.

ETI chief executive Dr David Clarke

said: “The UK has agreed to a legally

binding 80% reduction in CO2 by

2050, whilst maintaining a sufficient

supply of energy. The national energy

system in 2050 is unlikely to look like

it does today. It is likely to be much

more integrated across power, heat

and transport and that may require

different infrastructure elements,

particularly for heat and electricity

distribution and for new gases such as

biogas and potentially hydrogen. As

we set out down a pathway to 2050

we need to understand the potential

costs and performance of the energy

infrastructure that will carry energy

from where it is generated to where it

is consumed.

“The targets are challenging and if

we are to cut CO2 emissions whilst, at

the same time, meeting an anticipated

increase in demand, it is essential that

we maximise efficiency of energy

generation, transmission and

distribution.

“Whilst the majority of the fixed

infrastructure is currently used for

electricity or gas, this project will have

a more expansive scope and will also

consider hydrogen and heat

infrastructure.”

A Delmatic lighting

management system is

enabling Vestas Blades UK to

reduce lighting energy

consumption and cost of

ownership at its wind turbine

blade manufacturing facility

on the Isle of Wight. The

system is also used for testing

and monitoring of emergency

lighting.

The system is linked to the

predominantly high frequency,

dimmable fluorescent lighting

through DALI buswire

modules, enabling each

luminaire to be addressed

individually. The control

strategy delivers a high level

of flexibility, controlling each

zone to minimise energy

consumption in relation to

activities in the spaces. This is

achieved through a

combination of daylight

Enecsys, a supplier of long-life solar micro

inverter systems for residential and

commercial applications, has secured a further

£25m in equity financing to invest in its

growth plan.

Enecsys was founded in 2003 and its

patented technology was originally developed

at Cambridge University in the UK. Solar

inverters convert the DC power produced by

solar photovoltaic (PV) modules into AC power

for supply to the electricity grid.

Enecsys micro inverters are installed on the

rail behind solar modules, either one inverter

per solar module or one for every two

modules. The Enecsys micro inverter

represents a breakthrough in inverter design

for residential and commercial solar PV

installations as its technology has eliminated

components that limit inverter life.

Additionally the Enecsys micro inverter

enables solar PV systems to harvest between

5% and 20% more energy; it makes planning

and installation of PV systems easier and safer

due to the elimination of high voltage DC

wiring, and it enhances system optimisation

by monitoring the performance of each solar

module. Enecsys has recently launched its

products in Europe and North America and

the latest financing has been arranged to

facilitate substantial expected growth.

Climate Change Capital Private Equity led

this Series B equity financing with an

investment of £11m. The balance,

£14m, was secured from the existing

Enecsys investors, Wellington Partners, NES

Partners (formerly known as Bankinvest New

Energy Solutions) and Good Energies, who

together previously invested £8.5 million

($14.3 million) in Enecsys in a Series A

financing in 2009. The latest financing round

represents the largest private equity raise in

the European cleantech sector so far this year.

Solarplaza has announced RachelSolomon Williams, who is heading upDECC’s review of the feed-in tariffs(FiTs), will provide one of the keynotespeeches at its conference: “The SolarFuture, UK”. The conference will reviewthe UK solar photovoltaic (PV) marketsince the introduction of the FiTs lastyear and discuss the upcomingchallenges facing the industry.

Solomon Williams works in DECC’sOffice for Renewable EnergyDeployment and has been tasked withleading the FiTs review. At The SolarFuture, UK, Solomon Williams willprovide an overview of how well theUK FiTs have worked so far, share thelatest news about the review, and givesome insight into the government’sprojections for the coming years interms of market growth anddevelopment. The conference will takeplace on 29th June 2011 at Central HallWestminster, and will bring togethermore than 150 industry experts fromthe financial and business sector, thegovernment and regulatory authorities.To register for the conference visitwww.thesolarfuture.co.uk/registration.

The group CEO of the Electrical Contractors’

Association (ECA), Steve Bratt, has welcomed

the government’s announcement of a £60m

package to help the most vulnerable young

people into work, but warns without

employers providing real job opportunities,

this funding will be redundant.

“Apprenticeships generate £40 for every

£1 of government investment*, so taking on

an apprentice makes sound financial sense.

But for this to happen, government must

offer businesses tangible financial support to

ease the short term burden of investing in

the future. The £60m allocated through the

Supporting Youth Employment paper doesn’t

appear to tackle the issue of enabling

employers,” said Bratt. “In this current

climate, firms – particularly SMEs – simply

don’t have the money to invest in

apprentices, and funding work experience

places isn’t going to be enough to find jobs

for the 670,000 NEETs in the UK. In the craft

sector, we are sitting on a ticking time bomb.

If we don’t act now, we will not have the

home-grown talent needed to fulfil this

country’s potential. The consequences of that

will be more far reaching than most people

realise.”

Television presenter Dom Littlewood raised the

stakes in the Approved Cable Initiative’s battle to

beat defective cable when the extent of the problem

was highlighted to viewers of BBC One’s Fake Britain

programme on 26 May.

Producers for the programme have been working

with the Approved Cables Initiative (ACI) for the past

12 months and were keen to bring the issue of

defective cables to the attention of the public in its

new series which started last month.

The Fake Britain programme included footage

filmed last year as part of the BBC’s investigation

and highlights one of the key problems associated

with defective cables - the reduction of copper in

cables and the dangerous results such practice can

present.

As part of the feature viewers saw testing of fire

performance cable, which is used in essential fire

alarm wiring in schools, hospitals and other public

buildings, and how cables with reduced copper

levels fail current British Standards. During the

feature investigators were also taken to a storage

warehouse to show how much defective cable has

already been seized as part of the ACI’s

investigations.

The BBC isn’t the only party interested in the faulty

cable issue. The Health and Safety Executive (HSE)

shares the ACI’s concerns and is taking a keen

interest in its work having been tasked by Business

Innovation & Skills in 2010 to investigate the

Electrical Supply Industry (ESI).

Having already followed up on several cases

where distributors have imported defective cable,

the HSE believes potentially dangerous products

have entered the supply chain and it has taken

appropriate enforcement action. The HSE is actively

working with key stakeholders in the supply chain

and carrying out visits to wholesalers and

distributors to ensure that they understand their

obligations and are placing compliant products in

the market.

Last month the ACI revealed defective cable had

been found on sale in two major DIY Chain stores and

in both instances the product was withdrawn once the

issue was brought to the company’s attention. The

distributor that supplied the cable did not put a

general public product recall into effect and therefore

the public still remains unaware of the issue.

Peter Smeeth, spokesperson for the ACI said: “We

are extremely pleased the BBC decided to highlight

this issue as part of its Fake Britain series. Having

spoken with all the trade associations within the

electrical supply chain we know they are actively

supporting the ACI and the unsafe cable messages.

And with the ACI’s help third party approval bodies

are also beginning to change their rules for

admission, auditing and monitoring of cable

manufacturers in the UK and overseas. There is a long

way to go however before we can say that the

electrical supply chain is free of defective cable.”

� NICEIC’s Jobs for the Girls

campaign has received the backing

of Conservative MP Andrew Selous.

The NICEIC’s campaign aims to

encourage more women into the

electrical contracting industry and

dispel the myth trade professions

are a viable career path for men

only. NICEIC is also looking to

recruit more young females to its

OPINION GOSSIP/GOSSAGE

THE NEXT BIG ISSUEThe rapid increase of shale gas production in the US is already significantly influencing America’s energy mix. Just 1% of the natural gasmarket in 2000, it is now over 20% of the total, and is projected to be over 50% of production by 2030. And its abundance is deflatinginternational gas prices too.Already there is an enormous division even between European Union governments, as to its desirability. Some argue strongly for

exploiting the resource on greenhouse gas reduction grounds, replacing coal-fired electricity generation with gas-fired. The InternationalEnergy Agency estimates 15 trillion cubic metres of shale gas is theoretically available in Europe alone.The Polish government is gung ho, describing exploiting the resource as an “European priority.” As it takes over the Presidency of the

European Union Council next month, that stance is rather significant. In contrast, the French government is cancelling all shale gasexploration permits within its’ borders.Let me predict: Whether shale gas should be exploited will be the next big ecological issue in the energy field.

KEEPING THE CONCEPT ALIVEI have written before how Energy Secretary Chris Huhne keeps going out on a limb tohelp Iberdrola construct the first carbon capture and storage scheme at Longannet,Scotland. In response, the Spanish company is still threatening to pull out of the scheme.The project is the only one left in a competition set up back in 2007 by the previous

government. On offer was a prize of around £1bn. Initially, practically all the Big Sixwere anxious to host the experiment. But gradually all the others had taken fright atthe enormity of the project. And dropped out of the race. Only the Spaniards wereleft. When all the big expenditure cuts were being made last November, Huhne battedaway Treasury demands to drop the competition altogether. He even incurred thewrath of the CBI by removing all the carrots in the new Carbon ReductionCommitment instead, turning it into just another energy tax. All to keep the carboncapture concept alive.But now the word comes from Madrid. A £1bn bribe will not be sufficient to justify

the risk. At least another £400m will be needed. So Huhne is having to go cap in handto the European Commission, seeking top up funds there. But my bet is that even if hecan find the extra money, the flamenco dancing fraternity will try to up the ante evenmore. One thousand years ago, our ancestors used to fork out ever increasing amountsof Danegeld to try to keep Viking marauders away. I wonder what the equivalent namefor bribes to keep Spanish marauders in Scotland might be. An IberBung, perhaps?

Opening the door to a saleOf all the Big Six members, Scottish & Southern is undoubtedly the one which works hardestto retain its ‘honest citizen’ image. Consequently, endless opinion polls have placed thecompany some way ahead of its peers in terms of public respect.

Had you been in Guildford Crown Court recently, you might have come to a ratherdifferent conclusion regarding the company’s veracity. They were brought to court by SurreyCounty Council, and convicted on two counts of taking part in misleading selling practicesrelating to the “sales script”, used for certain between September 2008 and July 2009. Thiswas far from a case of a single over-enthusiastic rogue doorstep salesman. Company reps –who can earn over 50% of their salaries on commission - were using an official script and aprintout, deliberately designed to make residential customers believe they were overpayingtheir current supplier.

To quote Surrey County Council’s chief trading officer, Steve Payle: “Each doorstep sellerhad a printout, which he claimed showed customers were paying too much with theircurrent energy supplier. But the actual printout did not show this. “The seller actually didn’thave a clue, but the sales script was cleverly designed to put potential customers on theback foot, and to open the door to a sale.” Up until recently, Scottish & Southern had beenthe fastest growing supplier to the residential sector, with only Centrica having morecustomers. Should too many of their prospective customers get to hear about the Guildfordverdict, I would expect that trend to go smartly into reverse.

Gainfully employedMy devoted readers will recall, overthe years I have banged on about theenormous cost of developing nuclearfusion. In particular, the internationalresearch project ITER - EU. To date,nothing whatsoever has emerged fromover five decades of fusion research.Except the vague promise an enormousbreakthrough is just round the corner,which will revolutionise electricitygeneration for ever and ever. Butalways in about 40 years time.

From my point of view, the bestargument for the project is it keeps alot of highly qualified physicists ingainful employment. Gainful from theirpoint of view certainly, because as aMake Work exercise, it is running atabout €2m per job per year.

But the worm is finally turning. Foryears, the European Parliament hasbeen raising questions about ITER’sprofligacy. Parliamentarians evenrefused last year to approve aproposal from the EuropeanCommission to reallocate the triflingsum of €1.3bn from last year’sunderspent budget, to cover afinancing “shortfall” for the project.

Germany’s education and researchminister, is now describing ITER’sexpenditure as “exorbitant”, asbudgets have tripled from initialforecasts made just six years ago.Gnomically she adds: “Science has atendency to encourage politics to askfor more money”.

The days of this merry boondoggleat the European taxpayers expensemust surely be drawing to a close.Even I cannot justify spending €2m ayear in keeping my fellow physicistsemployed.

THERE IS ALSO good news to share: energy offers some of the

greatest opportunities for cost savings. Moreover, compared to

other cost-cutting initiatives, energy-management efforts often

deliver the fastest payback. Manufacturers can find substantial

savings if they know where to look.

Identifying the opportunitiesBefore implementing the required energy-management

technology and underlying infrastructure, companies should

assess overall consumption to identify real opportunities for

potential savings. In many cases, the first step for a plant

manager may be to simply understand where and how much

energy is consumed. This analysis requires all incoming

energy sources are monitored and reviewed. This may seem

daunting, but there is more good news:

Specialists are available to help. There are energy-

management experts who understand industrial processes

and know how to uncover energy-savings opportunities.

They provide guidance through the selection and

implementation process, help companies focus on the right

goals and best available technologies, and play a key role in

helping manufacturers understand tariff structures and how

energy bills are calculated. Pairing in-house expertise with

outside energy-management consultants can produce the

best recommendations for a successful energy-

management strategy.

Many companies already collect and profile the necessary

energy data. Many manufacturers already have systems in

place that collect the necessary energy-management data but

aren’t using the information in that way. The next step is to

use that information to make meaningful correlations

between energy consumption and production.

Energy in 3-DTraditionally, industrial energy consumption was seen one-

dimensionally as an unavoidable, unmanageable cost of

doing business. However, managing energy is actually a

three-dimensional challenge: minimise, economise, and

optimise.

� Manufacturers can minimise energy usage by taking

advantage of more efficient equipment or scheduling

production intelligently to minimise energy-intensive

changeover procedures.

� They also can economise energy costs by managing

where, how, and when energy is used in order to harness

it when it is least expensive, such as during off-peak times.

� Further, they can optimise energy use so as to achieve

production goals in the least expensive, most profitable

way while balancing the many variables inherent to

manufacturing. In other words, manufacturers can

actively manage energy as one of many inputs to the

overall production equation.

While electricity is the main example discussed here, there are

many different types of energy consumption in

manufacturing such as petroleum, natural gas, coal and

renewable. Regardless of the type of energy being consumed

and the purpose, manufacturers have an opportunity to

change their behaviour with regard to how they view energy

consumption in their facilities.

Less energy through intelligent motor managementElectric motors drive most production output and consume

the most electricity in the plant. Therefore, improved motor-

production efficiency. Fortunately, today’s advanced motor-

management solutions can yield immediate, measurable

bottom-line savings.

For example, variable speed drives can help significantly

reduce the energy used in manufacturing processes,

particularly those that involve fans or pumps with

changing flow rates. In fact, using variable frequency

drives to lower speed or flow by just 20% can reduce

energy use by up to 50%.

In any manufacturing process that requires less than 100%

of the designed speed, manufacturers should consider

integrating variable frequency drives for both low and

medium-voltage applications.

They can help significantly reduce energy costs and, when

properly applied, help eliminate valves, increase pump-seal

life, reduce power surge during startup, and contribute to a

more flexible operation.

New intelligent motor control centres (MCCs) also are

helping manufacturers capture and utilise valuable process

and energy data. Today’s MCCs monitor motor current and

thermal capacity, perform protective troubleshooting

functions, and provide detailed diagnostics to help avert

downtime. When properly deployed, these intelligent MCCs

are capable of providing users more detailed information

over longer periods of time, including critical motor energy

usage and performance data.

More cost-effective energy when consumption ismeasuredIn today’s deregulated utility market, manufacturers

increasingly can negotiate with multiple power providers.

However, shopping for better rates is difficult if companies

can’t control their power usage and don’t know their energy-

consumption profiles.

At the core of an effective monitoring program is a

network of digital power-monitoring devices that capture and

communicate power-consumption information. These devices

are used to measure electrical parameters associated with a

specific bus in a facility’s electrical distribution system. This

allows plant managers to gather detailed information on

power consumption in different areas of their facilities, on

specific machines (such as refrigeration compressors), and

even on individual product lines.

In addition to usage data, managers have access to power-

quality information that can improve productivity and

lengthen equipment life, further enhancing profits and

efficiency. Each department is seldom aware of its

consumption on a daily, weekly or even monthly basis. By

simply metering consumption, small opportunities for

improvement can be identified. Added together, these

provide a significant impact on energy usage, resulting in

immediate financial savings.

By developing an integrated energy-management program

based on accurate consumption and spending patterns, and

demand profiles, companies can calculate power-

consumption costs among various production lines. With

more accurate information reflecting actual production costs,

managers can make more informed business decisions.

Optimal energy by turning data Into knowledgeEnergy-management software can serve as a centralised

database for all energy parameters that can be accessed

within a facility or across multiple facilities in various

locations, using a standard Web browser. Being able to ‘see’

a problem often gives additional meaning to the information

derived from the data, and in turn leads to the proper

corrective actions. Armed with this insight, manufacturers can

see how energy consumption affects production capabilities

– positively or negatively – and can begin to make more

strategic energy-management decisions.

Energy-management software allows companies to

model their energy profiles by measuring peak demands

and quality parameters; determine demand patterns;

correlate energy consumption to weather patterns;

aggregate loads; and calculate energy costs by business

group, department or site. This modelling approach can help

save a significant amount of money because solutions can

be verified before committing capital expenditures for new

systems or equipment.

Once energy models of consumption and trends are

identified and charted, the possibilities are endless for

manufacturers to maximise their energy savings. By tracking

energy consumption patterns over time, a facility can use

historical data to verify utility bills, negotiate better rates, and

identify opportunities for demand management.

Case in point: One leading food and beverage

manufacturer quickly found negotiating the lowest electricity

rate required precise information about its power-usage

patterns, such as peak-power demand, time of peak-power

demand, and how often its various plants drew power at the

maximum rate. Armed with load-profile data compiled from

a power-monitoring system, the company was able to

renegotiate its agreement with its utility – reducing its

annual energy costs by up to 10%.

The information generated from monitoring software can

be trended and correlated to exogenous factors, such as local

temperature and humidity, and can provide the highest level

of utilities-management available. Systems that track usage

for the entire enterprise allow employees at all levels of the

organisation to have a common understanding of energy

use. This can help focus efforts on improvement potential

and drive consistent organisational behaviour in achieving

sustainable production goals.

Preparing for the futurePerformance pressures on manufacturing companies today

are greater than ever. They have to do more with less, and

do it faster. But while manufacturers have large energy

demands, they also have large opportunities for savings.

Technologies and expertise are available that allow

manufacturers to take control of their energy costs and

protect their business from energy-market fluctuations.

Bottom line: energy costs are controllable. The key is

identifying the energy-management goals, developing a

corresponding strategy, and putting the technology in place

that enables manufacturers to accurately monitor, analyse

and control energy consumption and quality.

MOST ORGANISATIONS TODAY recognise power quality is

an issue when it comes to the detrimental effect of power

disturbances, such as electrical noise and voltage impulses,

on sensitive electronic systems. The problem, however, is in

accurately calculating figures that demonstrate the financial

downside of dealing with bad power. Or simply put, how

can you establish the ROI when selecting from different

power protection systems?

For many organisations, power quality problems tend to

be ‘out of sight, out of mind’. While the frequency of spikes,

surges and other phenomena in power distribution is

generally understood and accepted, many fail to make the

connection between these irregularities and the impact to

the bottom line.

Over the last two years, we have worked closely with

industry leading customers to identify a technique to help

quantify and educate the industry about calculating real

return on investment. A major focus has been about

understanding the so-called ‘service burden rate’ – this is the

proportion of the price of a product allocated to cover

ongoing maintenance and repairs during the warranty period.

Our extensive research found that the typical service

burden rate ranged somewhere between 4% and 8% of the

price of the equipment or solution. But results gathered

from more than a thousand pieces of equipment installed

by Powervar customers showed a reduction of between

43% and 88% in warranty service costs. Even taking into

account the cost of buying the power protection

equipment, the ROI in these applications varied between

154% and a top level of 1,148%.

The benefits were not just financial either – there is a

‘softer ROI’ to consider, such as a reduction in service calls to

the manufacturer, improved customer satisfaction and greater

customer loyalty, as well as competitive advantage, important

in commodity based businesses largely driven by price.

Power supply problemsWhether power comes from a public utility or produced

onsite by a generator, the quality is always a challenge for

today’s modern electronic equipment. The power from

utility companies, even in developed countries, still largely

meets standards set in the very earliest days of electricity.

This was fine for many years until the advent of hi-tech

equipment incorporating sensitive components like

integrated circuits (ICs).

The power supply in the US and other developed nations

experiences an average of 8.8 hours of outages a year. Less

visible is the annual average of 79 hours in which the quality

of power is not satisfactory. Spread over the course of a year,

these incidents frequently cause costly damage or failures.

Such power irregularities are usually not immediately

fatal to equipment, but can produce cumulative damage

that will eventually cause sudden system failure or lock up

without warning. As soon as one component is replaced,

the cycle begins again and it is only a matter of time before

the failure is repeated.

Unburdening the service rateThe key to delivering a higher ROI for original equipment

manufacturers (OEMs) is a direct and fast reduction in the

service burden.

At Powervar, we focus on increasing equipment

reliability and uptime on the one hand and reducing

operational and service costs on the other. A notable

proportion of service problems result in ‘no trouble found’

service calls, most likely caused by power quality problems.

The ability to reduce these calls has a positive impact on

warranty costs and customer satisfaction.

By reducing service costs by up to 88%, or even 43%, as

reported in our study, customers are saving several millions

in some cases. In addition, the average number of help

desk calls dropped by 60%. These are savings that every

business, regardless of size or industry, wants to achieve.

Harder to measure is the impact on reputation and

market share, although these are very real benefits too. An

additional benefit is the increase in profits from service

contracts – so manufacturers can look to extend their

product warranties from say two to five years.

Clearly power quality is not the only factor impacting the

service burden rate. There are all sorts of software, training,

hardware and personnel issues that can also play a role, but

addressing and eliminating the ‘hidden’ and often hard-to-

trace problems caused by power fluctuations frees up time

and resources to sort out these other important areas.

Sensitive sectorsThere are several key market sectors where focusing on

controlling the power variable and protecting the equipment’s

processes will significantly increase ROI, including:

� Medical and healthcare systems – clinical and

diagnostic equipment, patient monitoring, patient

imaging and cardiac catherisation, etc

� Analytical instrumentation – gas chromatography, liquid

chromatography, mass spectroscopy and explosive

detection

� Banking and retail – point of sale, ATMs and kiosks

� Electronics manufacturing – semiconductors, industrial

automation, PCB manufacturing and automated test

equipment

� Graphics and printing – page layout and makeup and

digital feed presses

This is not a comprehensive list, but the common element

in all the sectors listed above is an improved ROI is not

just about cost savings, but also about these ‘softer’

benefits as well – so reducing service calls, keeping

customers happy, protecting brand image and gaining

industry advantage.

The financial case is clearOver the years, the power quality market and associated

UPS business, which is highly competitive and largely

driven by price, has been unable to demonstrate to

customers how much power disturbances are costing their

business and how power conditioning technology can

deliver savings directly to the bottom line. These real-life

examples are proof there is a financial case for investment

in such equipment.

The market is now entering a new era where the

investment is made on the grounds of measurable ROI and

demonstrable cost savings from areas such as service and

warranty costs. The industry must start to show customers

the kind of savings achievable by working in partnership

and by sharing information.

an investment in power conditioning equipment equal to

0.33% of its total system costs. On sales of almost $200m,

the service allowance was 6% or close to $12m annually.

The actual service cost has now been reduced by 70%

THERE IS NOW a growing case to say training in difficult times

can actually be more beneficial in the long term.

The publication of the first amendment to the 17th edition of

the wiring regulations is due out next month (1 July) and is

sure to create an increased demand for training in the

upcoming months.

Anyone involved in the design, erection and verification of

electrical wiring systems will be statutory obliged to get to grips

with the new regulations before they come into force on 1

January 2012.

For some electricians this obligation to go back to the books

can be seen as a hindrance, but for many contractors it is an

opportunity to develop new skills and strive for better things in

their work.

Everyone involved in the industry has a duty to at least

appreciate the new regulations so they can go about their work

confidently and in the knowledge it will comply with future

regulations.

This is because, ultimately, the regulations are in place to

protect and enhance the safety of customers, and as

professional electricians and electrical engineers, the

regulations ensure standards are maintained.

The electrical sector is a fast moving industry where new

products and technologies are being launched on to the

market every day. Standards which might have been suitable a

decade ago are now out of place and the need to update

regulations has become a necessary and vital tool to ensure

best practice.

In anticipation of the changes NICEIC has been running

one-day workshops to give contractors an early warning of

what to expect.

The sessions have been well attended and looked at

subjects expected to be included in the amendment such as;

the inclusion of a new electrical installation condition report,

changes to legislation relating to medical locations and new

guidelines which deal with the installation of surge protection

devices.

What we tend to see here at NICEIC is those who are quick

to invest in training tend to stay up to speed with technical

developments and are often in a better position to take

advantage of new business opportunities.

There is a commercial advantage to be gained by companies

with employees who are skilled in a number of areas and just

as the challenges may seem numerous the opportunities for

electrical contractors right now are significant.

The drive for sustainable buildings, the advancement of

electric cars and an increase in demand for renewable

technologies means electricians are well placed to take

advantage new opportunities in the market.

The challenge of exploiting these opportunities will only be

accessible through the development of new skills and without

the knowledge gained through training, the danger is many

contractors could get left behind.

Online trainingOne growing trend for NICEIC in recent years has been

the use of technology to provide access to training via

online services such as virtual reality. NICEIC can now

offer contractors online versions of several City and Guilds

courses as well as the 17th edition.

Last month NICEIC registered its 1000th online

customer for the for the City & Guilds 17th edition e-

learning course. Since its launch over a year ago the

online training facility has proved very popular with

contractors who find it difficult to take time off work.

Training in the 17th edition regulations could usually

involve electricians spending up to four days in a

classroom – four days when they are not earning any

money! The online facility means they are able to reduce

this amount by half and so training becomes something

which is viewed as beneficial and not a disadvantage.

Perhaps surprisingly it is not just the younger sparks

who are switched on to this method of training. The

1000th online customer at NICEIC was Les Keetch of

Power Distribute, in Kent. Les is 61 but said he prefers the

option to train online because it allows him to train at his

own pace – which is not always possible in the classroom.

ewly announced by APC by Schneider Electric, a global

leader in integrated critical power and cooling services, the

MGE Galaxy 300 UPS system provides a compact,

simplified and reliable solution for protecting small and medium

businesses, commercial buildings and technical facilities. It offers

reliable power protection and a robust and easy to install system at

the best price to performance ratio.

The new 3-phase UPS is a high availability solution which provides

a wide input voltage range for harsh electrical environments; on-line

double conversion topology for true isolation between input and

output with zero transfer time; parallel capability to increase system

redundancy and dual mains feed input for installation of one or two

independent power sources.

Galaxy 300 is fully RoHS (Restriction of the use of Hazardous

Substances) compliant. The power efficiency rates up to 93%, some

5% higher than other UPS systems with similar features. High

efficiency means lower operational and cooling costs over the

medium and long-term, a key factor in reducing the total cost of

ownership for electrical power protection.

“Feedback from our channel partners and core customers shows

that power availability, reliability, manageability and convenience are

the key issues that UPS systems need to address for low and

medium level power users,” explains Paul Tyrer, Vice President UK,

Ireland & Nordics, APC by Schneider Electric. “The new Galaxy 300

system has been designed with these requirements firmly in mind to

deliver a UPS which is easy to install and operate, at an affordable

price point. It is ideal for end users who are purchasing a 3-phase

UPS for the first time.”

The UPS system uses a double conversion online topology which

provides a regulated and reliable power supply. The Galaxy 300

offers up to 30 minutes of integrated battery back-up, internal

mechanical bypass to provide higher levels of power availability.

These features, combined with the compact design and easy

installation meet all the key requirements of customers looking for a

3-phase UPS in the 10-40kVA power range.

Users are able to monitor and manage power requirements locally

and remotely through a simple web/SNMP interface and a user-friendly

display available in 18 languages. The new UPS is also compatible with

APC’s InfraStruxure Central and InfraStruxure Operations software

applications.

InfraStruxure Central provides a vendor neutral and efficient method

to monitor company-wide multi-vendor physical infrastructure: power,

cooling, security, and environment. InfraStruxure Operations provides an

instant overview of data centre operations through inventory

management, PUE calculator, real-time device alarms, and location-

based drill-down.

For convenient power distribution, both three to three and three to

single phase power configurations are available. Servicing of the Galaxy

300 is greatly enhanced by allowing front panel access for ease of

maintenance in confined spaces.

Available from the electrical distribution network, the Galaxy 300

provides electricians with an easy-to-install UPS available from the same

distributor as their usual electrical products, with similar delivery times.

Options for the Galaxy 300 include an external battery cabinet for

increased runtimes and a parallel kit for 1+1 parallel redundancy.

Communication is supplied via a standard Network Management Card

for web/ SNMP functions or an optional card with additional features

including Modbus/ Jbus over RS485, Teleservice and environmental

sensors. All these features, combined with the start up and on–site

warranty service, makes the Galaxy 300 the easiest UPS in its class to

install, manage and maintain.

Like every UPS from APC by Schneider-Electric, the MGE Galaxy 300

benefits from the association of a strong brand and the support of a

world-class international services organisation. The new APC MGE

Galaxy 300 model includes a 1 year physical warranty with extended

warranty options.

AT A DISTRIBUTION SUBSTATION, RFI measurements were

undertaken to survey the condition of each of the

oil-filled circuit breakers making up a typical 11kV

distribution switchboard configuration commonly found in

the UK. A high percentage of 11/33kV switchboards have an

installed age of over 25 years. They are subjected to various

types of duty plus a varied level of maintenance. The trend

is to extend the maintenance period for medium-voltage

(MV) switchgear, which in turn creates the need for interim

non-intrusive condition monitoring techniques to offer

confidence in the equipment’s safety and reliability.

A baseline RFI scan was captured in an adjacent room

away from the surveyed switchboard. Measurements at the

rear of each circuit breaker were captured and compared

with the baseline. The observed uplift of frequencies

indicated a nearby discharge source, which was eventually

triangulated to one particular circuit breaker by comparing

the uplift in higher frequencies while moving the receiving

antenna along the rear of the switchboard. Further RFI

measurements were captured at the front of the

switchboard. A comparison of the front and rear RFI

measurements shows the uplift in the lower frequencies

was strongest to the front of the unit (FIGURE 5). These tests

were followed by complementary EMI measurements to

gather more information.

The HFCT uses inductive coupling to detect PD pulses

flowing to earth and is capable of picking up both local PD

in the cable end box and also the lower frequency PD

pulses coming from down the cable. The results of this

method confirmed the observations from the RFI survey,

with uplifts of up to approximately 50dB at 75MHz and

40dB at 200MHz. Time-resolved measurements also

showed pulse behaviour is similar to those obtained from

RFI measurements (Fig. 6).

The placement of HFCTs provides a means to trace the

likely source of the signals by comparing the uplift in

frequencies. The uplift reduces significantly as the location

of the HFCT is moved away from the suspect circuit breaker.

Repeated measurements on earth straps placed on adjacent

circuit breakers indicate the circuit breaker identified is the

source of the measured discharge activity.

The most advantageous setup for metal-clad switchgear

is to use an HFCT sensor in conjunction with a TEV sensor.

Transient Earth Voltage (TEV) measurements work on the

principle that if a PD occurs within metal clad switchgear,

electromagnetic waves escape through openings in the

metal casing. The electromagnetic wave propagates along

the outside of the casing generating a transient earth

voltage on the metal surface. TEV sensors are ‘capacitive

couplers’, which when placed on the surface of metal

cladding can detect TEV pulses as a result of PD internal to

the switchgear.

Observed peak TEV measurements on the main circuit

breaker tank reach 0dBm at a frequency of 100MHz.

Comparative measurements taken with the TEV sensor

located on the cable end box show a reduction in uplift of

approximately 20dB. The main circuit breaker tank is

identified as the likely source of the discharge. Time-

resolved measurements show pulse behaviour confirming

the results obtained from both RFI and HFCT

measurements.

The utility opened up the circuit breaker and found signs

of carbon at the cable end in the main tank of the

switchgear. Results of this study confirm that deploying

frequency spectra measurements and time-resolved

patterns from RFI, HFCT and TEV probes can be used to

pinpoint PD issues within switchgear. Using TEV sensors in

conjunction with RFI surveillance on metal clad switch gear

offers an additional capability in confirming and localising

the partial discharge source.

ConclusionRFI monitoring offers, and has proven to be, a routine non-

invasive and cost-effective surveillance technique that

complements and provides added value to other well

established HV asset monitoring techniques such as

thermal imaging and DGA analysis. As the practical

examples illustrate, measurements logged with an RFI

instrument platform specifically designed for substation

surveillance can assist in effective discrimination and

recognition of the RFI emissions radiated from potential

sites of insulation deterioration.

There are great benefits of combining the assessment of

RFI emissions with targeted deployment of other

complementary non-invasive electromagnetic interference

(EMI) detection techniques using the same RFI instrument

platform. The deployment of both ‘far field’ and ‘near field’

probes provide a diversity of sensors, which is of particular

importance with complex HV apparatus such as transformers

where the propagation paths for RFI are less well defined.

IT IS NEARLY TWO YEARS since the EU directive

governing the phasing out of incandescent lamps was

passed, and since its implementation in September 2009,

we have seen 100W, 75W and 60W lamps removed from

sale in the UK. By 1 September 2012 the remaining 40W

and 25W will be phased out, leaving the transition to

energy saving alternatives complete. But with a great

deal of confusion still surrounding the whole subject of

replacement bulbs – and a recent national newspaper

article fuelling consumer bewilderment about what low

energy options are available and where they can get hold

of them - there is work the industry can do to ensure any

misconceptions are laid to rest.

The findings of a survey, conducted by The Mail on

Sunday and published earlier this year, should be an

alarm call to the industry, claiming as it does ‘it is now

almost impossible to buy a direct replacement for any of

the old-style pearl light bulbs in any of Britain’s major

retailers.’

The fact is there are low energy replacements for

virtually every traditional light bulb available and it is up

to the industry to ensure this information is made widely

available and communicated throughout the industry

channels to reach the public.

When Click Scolmore joined forces with Energetic it

was to bring price-competitive products from the world’s

largest manufacturer of low energy lighting to the UK

market and to continue to drive the market with the very

latest in technological advances.

For many consumers the impression remains low

energy light bulbs are hugely expensive, take a long time

to reach their full (and in many cases inferior) light

capacity and are often larger than their traditional

counterparts. According to the survey the latter was cited

as the biggest single problem - “the new low-energy

alternatives are often far too large to fit into traditional

conical reading lamps and often stick out of the top.”

An enormous amount of work has been done in recent

years to develop the low energy lighting sector –

currently made up of CFLs, low energy Halogen light

bulbs and LEDs. The advancements made in LED

technology means that virtually any fitting in the home

can now accommodate a low energy lamp. A

comprehensive range of direct replacements that

includes candle, dimmable and reflector lamps is now

available and they don’t compromise on shape, size or

light output.

We are experiencing the same concerns with LEDs

today that we had with CFLs. CFLs have been around for

some years now and people are much more aware of

them, but when they were first introduced they were

considered a very costly, inefficient alternative, just like

LEDs are viewed today.

Yes low energy lighting is more expensive – but as

technology continues to drive the market and the

competition, so prices will continue to fall – but both

CFLs and LEDs produce similar levels of light for much

less power and therefore offer homeowners and

building operators substantial savings on the amount of

electricity they use.

Many of the Energetic lamps feature G-Start technology,

which combines a thermal management system with

acceleration in the vaporization of Amalgam. This results

in a light output of 60% in less than 15-20 seconds. This

technology in combination with the traditional

incandescent shape makes it a true direct replacement for

the standard incandescent lamp in look and feel and light

effect though saves 80% energy and lasts for 10 years.

The rate of progress in developing LEDs has been

tremendous and the light outputs now achievable from

LEDs means they are no longer used simply for decorative

or feature lighting but as functional solutions for task

lighting in all the main areas of domestic dwellings and

business premises.

With the industry primed for the January 2012 deadline

that will see the last incandescent lamps removed from

sale, there is still a job to do to get the message across to

the general public about the full potential that low energy

lighting offers and convince them there is a

comprehensive range of direct replacement products

available that will provide not just home owners but

t has been a very busy two months for Metartec with new

products being launched, the development of the

renewable energy subdivision, sponsorship activities and

exhibitions all happening.

Product developmentsMetartec is pleased to launch the latest additions to its ever

expanding, critical power product portfolio.

MILLI 3:1 UPS Series:The MILLI 10000VA and MILLI 20000VA are

online three phase in, single phase out topology

UPS’. These units are very versatile as up to 3

of them can be placed in parallel up to 60kVA

giving you the flexibility to increase the load the

UPS supports. This UPS series delivers optimal

power quality whilst providing superior power

management, resolving utility power protection

problems to critical equipment and applications.

The MILLI’s have programmable power

management terminals which means users can easily

and independently control load segments. During power

failure this feature enables users to extend battery time to mission

critical devices by shutting down the non-critical devices. These

UPS systems are ideal for retail units and educational institutions

due to their adaptability.

Solar energy:Metartec has also recently developed its renewable energy line of

business further to include a range of premium, competitively priced

solar devices to make green energy more affordable and accessible

to everyone. Metartec can supply leading international solar panels

and inverters for photovoltaic application and can create a tailor-

made solar solution to suit your renewable energy needs. Metartec

can provide up to date advice and recommendations for the design

and application of Solar PV generation, high quality solar panels,

fixing systems, inverters, DC cable and ancillary equipment.

Wind energy:The next step for Metartec is to expand into the wind energy sector

and there is already product development in the pipeline for this.

Metartec will soon be able to provide its customers with an

extensive range of high quality wind energy products and services

including wind turbines, complete with associated metering.

Metartec took centre stage at the FM Ireland exhibition 2011To preview these exciting developments Metartec showcased its

extensive range of UPS products and services at the FM Ireland

Show in the RDS, Dublin. The show provided Metartec with the

perfect opportunity to demonstrate to key decision makers in the

facilities management industry the benefits of its own brand open

protocol UPS systems. The show was also the ideal platform to

illustrate how Metartec has developed its customer and product

base over the past 12 months.

Metartec received very positive feedback on all ranges within the

business including its recent line of business, Metartec e3 (Electrical

Energy Efficiency). Many were keen to discuss how Metartec’s own

brand UPS products can be tailored to suit their critical power supply

needs and how the Metartec e3 products can save them money on

their operating costs.

Metartec will be exhibiting at the NI Electrical show on the 1 and 2

June and are looking forward to continually working with their

customers in securing further successful business opportunities.

Metartec sponsors singing successMetartec showed its support for the award winning Open Arts

Community Choir (OACC) by sponsoring a Gala Ball to celebrate their

10th Anniversary. The choir demonstrates how people from different

cultural backgrounds, with and without disabilities come together

through the medium of song to be positive ambassadors for Northern

Ireland. The event which took place at the Hilton Hotel, Belfast was a

singing success with over 300 local businesses and guests coming

together to help raise £13,000 towards the charities touring fund.

Steve McCallum, Metartec’s Business Development Director said:

“Metartec’s ethos is to provide solutions to power the future of our

customers and we feel that this philosophy should be incorporated

into all aspects of the business. With this in mind, we were delighted

to be involved with the Open Arts Community Choir and their fund

raising efforts.”

Beverley Whyte, Musical Director of the Open Arts Community Choir said:

“We have been overwhelmed by the support we have received from

local businesses, especially Metartec, and we would like to thank

everyone for their generosity.”

Metartec is very pleased with the success of the evening and is

delighted it was able to support such a worthwhile cause.

HISTORICALLY, DISCHARGE lighting has offered the highest

lumens per watt particularly for HPS Sodium. Industrial

luminaires have utilised 250w and 400w lamps. Some years

ago a steady change was initiated which transformed old

HPS installations into metal halide systems. The advantages

were: white light with improved colour rendition which

leads to a far more pleasant working environment with

greatly improved differentiation of colours thus assisting

product location and picking and clearer label indication.

A lesser known feature of metal halide lighting is the

incorporation of the scotopic effect. The human eye

responds more sensitively to white light than to golden

white (HPS) and the effect is a perception that the lighting

level is some 30% higher than a subjective reading from a

light meter.

Conversely, the average life of a metal halide lamp is

rated at some 15,000 to 20,000 hours against the HPS

average rating of 30,000.

Now the latest technology for discharge lighting systems

has widened the gap in energy saving potential for HID

lighting.

Dimmable electronic ballasts with control and monitoring

technology offer unique advantages for low bay and high

bay installations in retail, logistics, industrial and exterior

flood lighting applications.

Key features are:� Greatly improved lumen maintenance (>0.85). This

leads to the ability to reduce lamp power using the

dimming ability of the ballast whilst retaining or im-

proving working lumen output and Lux levels because

of the marked lack of degradation of the lamp.

� Average life of the lamp is doubled because of the high

frequency operation of the ballast. This system is far

“kinder” to the operating components of the lamp

thereby enabling extended life and consistent light out-

put. (to 40,000 hours using pulse-start metal halide

lamps)

� Reduced ballast losses (from 15% to 9%)

� Guaranteed consistent operation from -35°C to +65°C

� Instant hot restrike for HPS sodium lamps, reduced

strike and restrike times for metal halide

� Lower inrush current (25% of magnetic)

� 0.9 power factor

� Dimming via analogue circuit (0-10v) and digital circuit

(MADLI/DALI)

� Ability to save 30% to 60% of energy and operational

costs together with corresponding reductions in CO²

emissions.

� Fully controllable with monitoring. Dimming level,

scheduling, grouping and full lamp monitoring provided

by separate IP/Network-based system

Control of these systems is provided by the use of

daylight harvesting sensors (photocells),

occupancy/movement detectors (PIRs) and software based

control and monitoring systems.

Control and monitoring technology now allows control of

dimming, switching, scheduling and grouping of any

number of luminaires in an installation. All that is required is

to link together all digital ballasts in an installation to a PC

interface which offers unique flexibility and sophisticated

monitoring of the performance of the installation.

The monitoring function indicates the full status of each

ballast and lamp together with indication of an impending

lamp failure or system fault.

Communication of this information can be relayed over

the internet (the interface has its own unique IP address)

and no software is loaded onto the client’s internal network.

Therefore the security of an organisation’s IT system is not

compromised.

Total energy savings of a combined system incorporating

digital electronic ballasts together with a control and

monitoring system can often exceed 50% and payback can

be as short as 12 to 18 months with a very competitive life

metal halide lamp is

rated at some 15,000

At a major UK supermarket group, five logistics and

were specified and installed. These incorporate the e-LPT

dimmable digital ballast (250w or 400w) together with a

high reflectivity reflector (96% L.O.R.) Detectors

manufactured by Danlers provided daylight and movement

detection. Metal halide lamps from the Venture Pulse Start

range ensured optimum lamp life (Average 30,000 hours)

together with colour rendition of RA 68 and 4000k colour

There are operations areas in which movement of goods

was infrequent. During times of inactivity, the movement

detectors signal a reduction in lumen output (and thereby

energy saving) to 50%. When fork trucks start working in

these sections of the warehouse, the lighting ramps up to

the pre-set maximum. In this case, a lamp power of 280w

gave long term improved lux levels whilst still utilising 400w

lamps. Higher wattages could be selected at any time from

a single control point.

Each of these 65,000 sq m ( 600,000 sq ft) warehouses

THE FACT A SOLAR device is both a d.c. environment and a

non-interruptible source of current whenever the sun is

shining makes things pretty complicated compared to our

customary a.c. world. Ensuring the safety of solar power

generating facilities is a tricky business, because there are

very specific risks inherent to this kind of electrical

equipment.

One of the most important safety components is the

fuse. Installed in series, its purpose is to conduct normal

current and to protect equipment and people from the

potential effects of overcurrent, like overheating / fire /

external arc / etc.

A new specific standard for fuses was published in 2010:

IEC 60269-6 Ed 1 Low–voltage fuses Part 6: Supplementary

requirements for fuse-links for the protection of solar

photovoltaic energy systems. This new type of fuse is

currently called ‘gPV’: general purpose fuse for photovoltaic

applications.

The requirements of that standard apply to fuse-links

protecting PV strings and PV arrays in equipment for circuits

of nominal voltage up to 1500Vdc. They define, for example,

the minimum breaking capacity (mbc), rated breaking

capacity, and conventional times and currents.

Why a dedicated fuse?gPV Fuses are designed and tested specifically for DC

applications. When a fault occurs in a DC circuit, the absence

of natural voltage zero crossing makes the interruption of

DC faults more difficult than the interruption of AC faults

because only the arc overvoltage generated by the fuse will

force the current to decrease to zero.

For direct current, the correct interruption depends on

three parameters:

� the value of the DC voltage,

� the value of the ratio L/R (time constant) of the fault

path

� the magnitude of the prospective fault current

The short circuit current depends on the number of strings

and the Isc of the solar panels. The possible low level of

overload to be eliminated in photovoltaic equipment is a

very arduous condition for a fuse!

No fuse is required for PV installations with number of

strings lower than 3 because the short circuit current is too

low to melt the fuse.

Conventional times and currents for gPVDespite globalisation, there are still some differences between

standards. The first example is conventional times and

currents. Between an IEC gPV fuse and a UL gPV fuse, non-

melting gates and melting gates are not the same:

gPV fuses 0-30A @1h

Inf If

IEC standard 1.13*In 1.45*In

UL standard In 1.35*In

MERSEN 1.13*In 1.35*In

To satisfy customers in all markets Mersen’s HP6M and

HP10M photovoltaic (PV) fuse series were engineered and

designed specifically for the protection of photovoltaic

systems in compliance with both standards. Their enhanced

fuse construction makes them suitable for continuous

temperature and current cycling withstand, adding to

system longevity.

The 600VDC rated HP6M and the 1000VDC rated

HP10M, designed for low minimum breaking capacity

capabilities of 1.35 times the fuse’s rated current value,

allow for safe circuit interruption under typical low fault

current conditions produced by PV arrays. Off-grid or on-

grid PV systems can be protected from unexpected

ground faults and line faults using Mersen’s

HelioProtection fuse line.

Dedicated photovoltaic fuses have to be designed and

tested in accordance with the gPV standards for PV

applications to ensure personal safety and photovoltaic

circuit protection.

IT IS NEARLY TWO YEARS since the EU directive

governing the phasing out of incandescent lamps was

passed, and since its implementation in September 2009,

we have seen 100W, 75W and 60W lamps removed from

sale in the UK. By 1 September 2012 the remaining 40W

and 25W will be phased out, leaving the transition to

energy saving alternatives complete. But with a great

deal of confusion still surrounding the whole subject of

replacement bulbs – and a recent national newspaper

article fuelling consumer bewilderment about what low

energy options are available and where they can get hold

of them - there is work the industry can do to ensure any

misconceptions are laid to rest.

The findings of a survey, conducted by The Mail on

Sunday and published earlier this year, should be an

alarm call to the industry, claiming as it does ‘it is now

almost impossible to buy a direct replacement for any of

the old-style pearl light bulbs in any of Britain’s major

retailers.’

The fact is there are low energy replacements for

virtually every traditional light bulb available and it is up

to the industry to ensure this information is made widely

available and communicated throughout the industry

channels to reach the public.

When Click Scolmore joined forces with Energetic it

was to bring price-competitive products from the world’s

largest manufacturer of low energy lighting to the UK

market and to continue to drive the market with the very

latest in technological advances.

For many consumers the impression remains low

energy light bulbs are hugely expensive, take a long time

to reach their full (and in many cases inferior) light

capacity and are often larger than their traditional

counterparts. According to the survey the latter was cited

as the biggest single problem - “the new low-energy

alternatives are often far too large to fit into traditional

conical reading lamps and often stick out of the top.”

An enormous amount of work has been done in recent

years to develop the low energy lighting sector –

currently made up of CFLs, low energy Halogen light

bulbs and LEDs. The advancements made in LED

technology means that virtually any fitting in the home

can now accommodate a low energy lamp. A

comprehensive range of direct replacements that

includes candle, dimmable and reflector lamps is now

available and they don’t compromise on shape, size or

light output.

We are experiencing the same concerns with LEDs

today that we had with CFLs. CFLs have been around for

some years now and people are much more aware of

them, but when they were first introduced they were

considered a very costly, inefficient alternative, just like

LEDs are viewed today.

Yes low energy lighting is more expensive – but as

technology continues to drive the market and the

competition, so prices will continue to fall – but both

CFLs and LEDs produce similar levels of light for much

less power and therefore offer homeowners and

building operators substantial savings on the amount of

electricity they use.

Many of the Energetic lamps feature G-Start technology,

which combines a thermal management system with

acceleration in the vaporization of Amalgam. This results

in a light output of 60% in less than 15-20 seconds. This

technology in combination with the traditional

incandescent shape makes it a true direct replacement for

the standard incandescent lamp in look and feel and light

effect though saves 80% energy and lasts for 10 years.

The rate of progress in developing LEDs has been

tremendous and the light outputs now achievable from

LEDs means they are no longer used simply for decorative

or feature lighting but as functional solutions for task

lighting in all the main areas of domestic dwellings and

business premises.

With the industry primed for the January 2012 deadline

that will see the last incandescent lamps removed from

sale, there is still a job to do to get the message across to

the general public about the full potential that low energy

lighting offers and convince them there is a

comprehensive range of direct replacement products

available that will provide not just home owners but

building operators too, with products that look

aesthetically pleasing and will offer huge energy and

therefore cost savings.

CO² emissions were reduced by a corresponding 48%HID lighting for industrial and commercial applications

currently competes with fluorescent T5, LED and Induction

lighting alternatives. The most important advantages of HID

lighting include:

� Low installed cost

� Low maintenance

� High lumen maintenance over a greatly extended lamp

life

� Ability to dim to 35% (HPS) and 50% (MH)

� Superior performance in cold environments (-35°C to

+65°C)

Of particular relevance is the performance of HID lighting

in high mounting point applications. With exceptional

lumen output (42,000 lumens for a 400w MH lamp), the

system offers a unique ability for light distribution to be

specifically controlled for both narrow aisle situations and

wide spaced open areas.

In high ceiling retail situations, metal halide lamps used

in conjunction with prismatic glass or acrylic reflectors, offer

a combination of controllable downlighting with a high

component of uplighting. This provides an important

degree of reflected light when used with the benefit of light

coloured floor and ceiling finishes.

For external lighting situations metal halide or HPS

lighting is still a popular light source of choice for high

power, controllable and low-maintenance installations.

RISING TO THE CHALLENGEThe tallest building in Reading is enjoying substantial energy savings thanks to the installation of Tyco Thermal Controls HWATsingle pipe hot water temperature maintenance system.

NG Bailey opted for Raychem’s HWAT M self-regulating cable and the HWAT-ECO control system as an alternative to aconventional recirculation system for the domestic hot water.

The Raychem hot water temperature maintenance system offers an intelligent way to supply hot water which does not requirereturn pipes, valves or pumps.

The system works by attaching a self-regulating heating cable to the single hot water pipe which keeps the water at the desiredtemperature. Because the temperature of the cable adjusts at any point along the pipe depending on the local conditions of the pipe network, theindividual pipe is heated everywhere and the temperature can be selected up to that of the storage tank temperature.

no unintentional access to the busbar.Steve Dyson, product manager, said: “It is common for

consumer units or JK boards in the final distribution to haveoutgoing ways left blank to allow for the addition of othercircuits in the future. Some consumer unit blanks aregenerally fitted to the front cover of the board, so the busbarteeth need separate covers or ‘boots’ for protection. Makingsure that the blank is securely fixed and will not come awayeasily is both the safest solution and also the mostconvenient for the installer.”

PROOFOF SAFETYUsed in conjunction with a two-pole voltage tester, Megger’s new MPU690proving unit provides a fast and dependable method of confirming that circuitsare dead prior to carrying out work on them.

The new proving unit features time-saving automatic operation and its highoutput power makes it suitable for use withlamp type voltage testers as well as withmore modern units.

To ensure safety, when a two-polevoltage tester is used to confirm that acircuit is dead, the correct operation of thetester itself must be verified using a knownlive voltage source both before and afterchecking the circuit. Often, however, nosuitable voltage source is available. The newMPU690 provides a convenient and reliablealternative.

EFFICIENCY BOOSTERMODE FORUPSAPC by Schneider Electric, a global leader inintegrated critical power and cooling services hasreleased its highly anticipated Efficiency BoosterMode (EBM) operationfor MGE Galaxy 7000Uninterruptible PowerSupplies (UPS)connected in parallel.The new EBM featurespromise reduced UPSoperational expenses.

The new firmwareenables customers tomaintain the highestlevel of efficiency(reducing losses by upto 20%) in an MGEGalaxy 7000 parallelsystem. It achieves thisby automaticallyplacing underutilised UPS power modules into sleep(standby) mode when the system load is much lowerthan the installed capacity. It does this without anycompromise to system redundancy, at the same timeeliminating the cost overhead created by poweringand cooling underutilised infrastructure.

Once the system load starts to increase, EBMreacts accordingly and will command additional UPSpower module/ s to commence sharing the load,again without affecting the designed redundancy.
