EDF ANNOUNCES PROCESS TOEVALUATE OWNERSHIP OPTIONSThe EDF Group has announced it is

initiating a process to evaluate

ownership options for its electricity

distribution business in the United

Kingdom.

EDF Energy is the largest electricity

distribution network operator in the

UK. It serves London, the South-East

and East of England which account for

40% of the UK’s GDP. It has significant

future opportunities from grid and

distribution network technologies.

EDF Energy is also involved in

unregulated networks businesses

comprising the development, delivery

and management of safe, sustainable

and profitable electrical and multi-

utility networks for owners of major

infrastructures.

Pierre Gadonneix, EDF chairman

and CEO said: “The process to

evaluate ownership options for our

UK electricity distribution networks is

part of the announced asset

divestment programme, aiming to

reduce our net financial debt by at

least €5 billion. It is also part of our

development strategy in the United

Kingdom, which is a key market in

Europe for the Group. This process

follows British Energy’s acquisition

which facilitates EDF’s plans to

develop new nuclear power in the UK

and significantly strengthens our

position as a UK energy player.”

Vincent de Rivaz, EDF Energy CEO

said: “As a responsible company, EDF

Energy will continue the dialogue with

its employees and other key

stakeholders throughout this

evaluation process. This combination

of three regulated networks covers a

key region vital to the UK economy. It

has a highly experienced and skilled

workforce which has a strong track

record of delivery and is well placed

for growth.“

EDF Group financial advisors are

Barclays Capital and Deutsche Bank

AG London Branch. Additional support

will be provided by BNP Paribas.

Megaman has joined a national

drive to reduce carbon

emissions by 10% in one year.

As one of the first companies to

sign up for 10:10, Megaman has

committed to reduce its carbon

footprint and get staff, customers

and suppliers involved.

Four key areas are being

targeted by 10:10; electricity, on-

site fuel use, road transport and

air travel. The Energy Saving

Trust and Carbon Trust have

agreed to help people to reach

their 10:10 target by providing

advice about energy saving

measures through their help-

lines and websites. Megaman’s

John Murphy, commented: “At

Megaman we are lucky we are

able to not only reduce our own

carbon footprint but help others

reduce theirs by using our

energy saving lamps. As a

company with a strong

environmental ethic we are

proud to be a part of this

initiative”.

FIRE PROTECTION IN TOWER BLOCKS A PRIORITYThe fire integrity of tower blocks

must be made a priority, says safety

charity the Electrical Safety Council

(ESC).

Commenting on the BBC’s report

on the fire risks in London’s tower

blocks (http://news.bbc.co.uk/1/hi

/england/london/8290103.stm), Phil

Buckle, director general of the ESC

said: “It’s crucial electrical work

undertaken on behalf of council

landlords is rigorously checked to

ensure that fire regulations have not

been breached, particularly in high-

density accommodation buildings

where the rapid spread of fire can

have devastating consequences.”

The BBC’s report uncovered a

series of fire hazards in a tower

block in Hounslow, west London,

including holes bored through

ceilings to accommodate electric

cables, which would accelerate the

spread of fire.

Phil Buckle continued, “A

building’s structural performance

during a fire can be seriously

compromised by inadequate fire

sealing and ‘making good’ after

modifications that penetrate the

walls and ceilings of a building, such

as the installation of electrical cables.

Maintaining the structural fire

protection in buildings and ensuring

fire regulations are met is crucial in

preserving life in the event of a fire."

Speaking at an Engineering the Future

fringe event at the Labour Party Conference

Lord Drayson, minister for science and

innovation, called for the equivalent of

chief technology officers in government

departments.

Lord Drayson told delegates: "It is

engineers and technologists that will get

this country back on track. To achieve this

and to implement government priorities

effectively and strategically, we need more

technological knowledge within the

government. Science, technology and

engineering represent Britain's ‘big three’

for the future. They are essential to our

economic growth and to maintaining our

quality of life as we tackle the major

challenges like climate change. We cannot

build for the future without world -class

engineers."

The minister’s comments were warmly

received by the audience who agreed the

need was not simply for advice but for

expert representatives who could help

implement new engineering technologies

and projects in practice.

Jonathan Flint, chief executive of Oxford

Instruments, defined engineering as a

discipline that benefits society while

generating wealth. Calling for a rethink of

the place of engineers in corporate

hierarchies, he pointed out engineers

needed to acquire management and

communications skills to complement their

highly-valued numeracy and attention to

detail. “Too often, engineers can limit their

opportunities. We want to see more of

them with the management training that

will put them on boards of companies,”

he said.

Philip Greenish, chief executive of the

Royal Academy of Engineering, said: “Lord

Drayson’s recognition of science,

technology and engineering as Britain’s

‘big three for the future’ is excellent news,

as is his acknowledgement that there

should be chief technology officers in

government departments. The next step is

to ensure practical steps are taken to

follow up on these bold new proposals.

Government, business and industry,

education providers and the engineering

community must all now step up to the task

of actually making things happen.”

being implemented to replace EN954-1 and

are aimed at achieving an acceptable risk

level for machinery. Wieland’s technical

seminars have been designed to provide a

thorough review of the steps necessary to

achieve compliance with the new regulations.

■ Twenty million pounds is to be invested in

innovative energy efficiency measures to cut

emissions and energy bills in central

government departments it has been

announced. The allocation is part of the

package of £405m low carbon funding

announced at the Budget in April to help

establish the UK as a market leader in

renewable technology and advance green

manufacturing.

The £20m will be invested in helping

government departments go further, faster in

reducing their carbon emissions across their

estates, realising both carbon and financial

savings. Successful solutions can then be

replicated elsewhere in the public sector.

Energy and climate change minister Joan

Ruddock said: “We know it’s important to

show leadership in this area – if we want

everyone else to retrofit their homes its

important government buildings also get

some treatment.

Some of the money will go on energy

efficiency, some on smart meters, some on

low carbon cars, and some will go on

mapping the possibilities of renewable

energy on public land – that will be led by

the Forestry Commission.”

WEMBLEY GIG PROVES NICEIC’S BIGGEST EVER

Alstom Wind has signed a contract

with Welsh company Pennant Walters

for the construction of a new wind-

farm – Alstom’s first windfarm contract

in Wales.

The 26 MW Maesgwyn windfarm, to

be built on the site of the former

Maesgwyn and Derlwyn coal mines

north of Glyn-neath, South Wales, will

comprise 13 of Alstom’s ecotècnia 80

wind turbines and is expected to be-

come operational in October 2010.

Under the terms of the contract, Al-

stom will supply, install and commis-

sion the windfarm, followed by

operation and maintenance for the

first five years.

Maesgwyn is Alstom’s second wind

project in the UK following a contract

signed earlier this year for the 15 MW

Clachan Flats project in Scotland. It

marks the entry into the UK market for

Alstom’s ecotècnia 80 wind turbine. It

is also the first windfarm project for

Pennant Walters, whose main business

activity is mining and heavy machinery

leasing but which has diversified into

renewable energy and general devel-

opment (such as the new Ffos Las

racecourse) in recent years.

The contract, worth approximately

�30m follows another recent order for

Alstom in Wales announced in April,

the turnkey 2,000 MW Pembroke gas-

fired power station being built for RWE.

■ Schools secretary, Ed Balls, has pledged a further £11m to fund

an additional 2,300 training and education placements from

September 2010. Iain Macdonald, head of education and training at

the Electrical Contractor’s Association said: “The government’s

investment in vocational training is welcome, but the £11m figured

recently announced by Ed Balls is a drop in the ocean and nowhere

near enough to bolster an industry on the edge of a skills crisis. This

extra funding is a knee-jerk response to the unexpectedly high take-

up of apprenticeships and other training placements, and is yet

another example of the current government’s ignorance about the

value of vocational qualifications. Our estimates suggest to

counteract the current worsening skills crisis in the building services

sector alone, Ed Balls should have been quoting closer to £100m,

not £11m. Training is essential to protect UK industry and safeguard

its success into the future.”

■ Professor Christopher Snowden began his year-long term of office

as president of the Institution of Engineering and Technology (IET) on

1 October. He is currently vice-chancellor and chief executive of the

University of Surrey and has enjoyed a varied career with

considerable experience of the international microwave and semi-

conductor industry.

New research that could solve the problem of radar in-

terference from wind turbines is underway. Energy and

climate change secretary Ed Miliband announced the

£5.15m pound research in his speech to the British

Wind Energy Association.

The £5.15m fund is made up of £1.6m from wind

companies, £2m from the Crown Estate and £1.55m

from DECC.

Aviation radar objections are one of the largest

causes of wind planning applications being rejected or

withdrawn in the UK. There are currently objections to

over 5GW of wind farms that are in the planning sys-

tem by NATS, (formerly National Air Traffic Services).

Miliband said “I know that delays in the planning

process can cause uncertainty and be a barrier to in-

vestment in renewables and there are specific issues in

connection with aviation and radar that need to be ad-

dressed. This R & D project could resolve wind impacts

on radar in the UK and potentially release 5 gigawatts

of wind power. By 2020, around a third of UK electric-

ity needs to be from renewables, the bulk of that com-

ing from wind. We are making very good progress - it

took the UK 14 years to build our first 1 gigawatt of

wind and we’ve now passed the 4 gigawatt mark, with

the last gigawatt added in just a year.”

Aviation objections are currently holding up over

5GW of wind energy in the planning system and a fur-

ther 5.5GW in early stages of development.

A number of these projects have been granted con-

sent by DECC, the Scottish Executive and local planning

authorities on the proviso that a solution to their poten-

tial radar interference is implemented. If the research is

successful then these conditions could be lifted, allow-

ing these projects to start construction.

Any solution to the problem will mean a much

swifter and more certain planning process for future

wind projects.

NATS director for development and strategy, Ian

Hall, said: “NATS is delighted to be at the centre of a

project to support the UK’s renewable energy target

and we welcome the funding to enable us to continue

our work in this sector. The investment is a significant

step and our experts will work with Raytheon to exam-

ine the potential of this approach.”

Companies from across the UK suc-

cessfully helped to cut the amount of

carbon emitted from their buildings

during Cibse’s 100 Hours of Carbon

Clean up Campaign 2009. Universities,

consultancies, museums, hotels and

offices all signed up to reduce energy

use during the six week campaign.

This was the fourth Carbon Clean up

Campaign run by the Chartered Institu-

tion of Building Services Engineers

(Cibse) – the campaign was open to

companies from all sectors who

wanted to reduce the amount of car-

bon emitted from their buildings and

to motivate fellow employees to get

involved. In return they received ac-

cess to expert advice, energy saving

tips, training events and motivational

stickers & posters.

Organisations who dedicated time

to energy saving activities during the

campaign included BBC Wales, Trans-

port for London, EDF Energy, London

Fire Brigade and the Maritime & Coast-

guard Agency. A number of industry

representatives also signed up such as

CABE, Arup, BDP and HLM Architects.

Commenting on the campaign,

Cibse CEO Stephen Matthews said:

“Once again we are delighted with the

range of organisations that have taken

part in the campaign and displayed

their commitment to cutting carbon

emissions. With sustainability continu-

ing to be a key issue, it is more impor-

tant than ever to bring energy saving

measures into the workplace, and to

engage and involve employees in tak-

ing small steps to achieve bigger re-

sults.”

Philip Belton, engineering manager

for Spire Tunbridge Wells hospital, ex-

plained why he found the campaign

helpful: “Participating in the Cibse car-

bon off campaign enabled a dramatic

increase in staff engagement and

commitment to carbon reduction, and

personally I gained and improved a

number of key skills through out the

campaign which I have used as a foot-

ing for further projects. “

CARBON SAVING CAMPAIGN

■ Prysmian has supplied its FP cable for what is said to be the largest

renewable biomass co-firing project anywhere in the world, at the Drax

Power Station in North Yorkshire. The new facility will enable Drax

Power Station to receive, handle, store, process and co-fire with coal a

variety of biomass materials. The new facility enables electricity to be

generated when forestry residues, agricultural bi-products and energy

crops are burnt alongside coal in the existing coal-fired boilers to

provide heat. This process provides benefits to the environment and

the economy. It is a low cost, efficient renewable technology and as

biomass directly replaces burning coal, overall CO2 emissions are

reduced.

■ The forty winners of the prestigious British Safety Council’s

International Sword of Honour 2009 have been announced. The

winning organisations have all been recognised as having exemplary

health and safety systems that are among the best in the world. The

winners will be presented with the Sword of Honour at a Ceremony in

Goldsmiths’ Hall, London on Friday 27 November 2009. In order to

compete for the BSC Sword of Honour, organisations must be able to

demonstrate their specific site has achieved the maximum rating in the

BSC’s Five Star Health and Safety Management System. Inaugurated in

1979, only 40 swords are awarded world-wide.

IN BRIEF

Embarrassed by the closure of wind firm Vestas’ blade

manufacturing plant on the Isle of Wight, energy secretary

Ed Miliband went to the TUC annual conference in

Blackpool. He did so largely in order to announce a £4.4m

grant to Clipper Wind Power. This is to help develop 70

metre long blades for its Britannia project, a 10MW

offshore wind turbine.

He got lots of applause from the TUC, and lots of

favourable press coverage. Strange that. Because the very

self same scheme was announced over 2 years ago by his

predecessor John Hutton. And by last year, Crown Estates

had already agreed to buy the turbine. Just shows you

can’t have too much of a good thing.

OPINION

CHANGE AT CONSERVATIVE HQ? GOSSIP!GOSSAGE!

As befitting his position as the most junior member of the

shadow cabinet, Greg Clark, the Conservative energy

spokesman, has only ever been invited to undertake an

extensive policy interview by the least read of all the national

newspapers. The Independent on Sunday.

In case you are not one of the few hundred people who

bother to buy this newspaper, let me give you the gist of

what he had to say. It was almost entirely about his party’s

attitude to climate change. Which you will be pleased to

learn he was in favour of being against.

Indeed he pledged combating climate change is every bit

as big a priority for his party as it is for the other two main

parties. So we can expect a continuation of existing and

planned interventionist policies, almost all of which seem

inevitably to have the effect of forcing prices up - and so

increasing the record numbers in fuel poverty.

There are now over 5 million British households who are

paying over 10% of their disposable income to try to keep

warm in winter: a dreadful indictment. The government will

not want to be reminded of its pledge at the 2005 general

election to remove all vulnerable households from fuel

poverty by 2010.

So will Mr Clark be taking a portion of the billions of

pounds due to be raised by auctioning permits under the EU

carbon trading scheme - one of the very policies increasing

fuel prices - and dedicate it to improving the homes of the

fuel poor? Sadly the answer is: No. On the contrary, his only

declared beneficiaries will be companies building

experimental projects to capture and store carbon.

These companies are the oil giants like Shell or BP, or

electricity companies like Eon and RWE. All make substantial

profits running into billions every single year. From which

they could perfectly easily fund such research projects.

But, rather than trying to help the least privileged in

society, the Conservatives intend that scarce public money be

lavished upon these wealthy multinationals. On this

evidence, who can believe the Conservatives have changed?

Or as Mr Clark’s leader, Dave Cameron would have it,

“decontaminated the brand?”You have to laugh. The European Commission started congratulating itself far tooearly, upon the successful completion of the first stage in its three year phase-out ofincandescent and low-efficiency halogen light bulbs. As from this autumn, nowhere inEurope should you be able to buy a clear bulb of 100 watts or more. (Bet you can. Butthat is another issue).

However tungsten halogen lamps of the same wattage are not supposed to bebanned yet, for the very sound reason that credible alternatives are currently notdeemed to exist. The trouble is, the way in which the product list was drawn up, thereare a whole range of specialist lighting facilities which now face being outlawed. Andones that everybody thought should be outlawed, but weren’t.

For instance, EU lawmakers omitted to exempt emergency ballasts and explosionproof lamps from their rules, which could result in serious security risks in theinstallations where these products are used. They also managed not to ban certain ofthe least efficient halophosphate fluorescent lamps.These of course are just the aberrations that have been spotted to date, mistakeswhich officials are even now beavering away to rectify. I would bet you LombardStreet to a china orange that there are an awful lot of other changes to thelegislation that will have to be corrected sooner or later. And that is before we get onto trying to eliminate all 60 watt incandescents and their equivalents.

CONGRATULATIONS TOO EARLY

DÉJÀ VU IN BLACKPOOL

My friends in the nuclear industry have been hugging themselves with joy at

the results of the general election in Germany. All German governments are

coalitions. But out from the new government have gone the Social Democrats,

a party which has long regarded the Great God Atom as the work of the devil,

and want all nuclear power stations closed tomorrow.

Unlike their counterparts in the UK. But then the German party doesn’t

have a leader whose brother is head of PR for one of the biggest nuclear

companies (step forward Andrew Brown, of Electricite de France).

Into their place in the Berlin government have come the Free Democrats. A

very different set of politicians. Don’t be fooled by the fact that, in the

European Parliament, they form part of the same political group as our own

cuddly anti-nuke Liberal Democrats. These guys think the nuclear power

stations are just fine and dandy. And should be kept running as long as

possible. In that vulgar phrase, “they must go until they blow.”

The presumption of the nuclear cheerleaders is this must mean they will be

getting the go ahead to start building new power stations in Germany. I have

news for them. Not only does re-elected Chancellor Angela Merkel have no

intention of sanctioning any new construction. She also plans a special

windfall tax on the operators of the existing power stations.

Her argument is, as a result of the new extension-of-life policy, these

companies (EoN, Wattenfall , RWE) will all be earning unexpected extra

revenue each additional year they operate. She wants a portion of those

monies, thank you very much. Which she plans to spend on – wait for it –

energy efficiency and renewables programmes. You can almost see the

nuclear boys glowing in the dark. With rage, of course.

GLOWING IN THE DARK

10 Electrical Review November 2009

CABLE MANAGEMENT

CONTRACTING companies, and building product

manufacturers less familiar with public sector work, have

been quick to throw their hats into the ring in an attempt

to secure a slice of much-needed business. A good

example of this scramble to win work was the 50 or so

contractors who applied to be part of the academies

framework in England. The framework, part of the

Building Schools for the Future (BSF) initiative, has £4bn

to spend on the design and build of academies.

Those working on public sector contracts – especially

education related – will know they are awash with

acronyms, ranging from the well-accepted PFI (Private

Finance Initiative) to BSF, PCP (Primary Capital

Programme), PFS (Partnerships for Schools) and LEP

(Local Education Partnership). Given the huge sums of

money being invested and the manner in which the

money is allocated and spent, we feel that knowledge of

public procurement processes is vital in assisting clients

with achieving the most desired outcome.

Most school and many hospital projects are delivered

via PFI. We find this makes each job very different and

calls for closer contact with site – more time is spent there

than working off-site with an architect or consultant as

would be normal on a ‘private’ project. There are also

decision makers up and down the chain of command and

it pays to remain in close contact through the

specification, installation and hand-over.

However, it is possible to push aside the jargon and

buzz words in order to understand what’s required of

new-build and refurbished educational and health

facilities. Quite simply they must provide an ultra-modern

environment for today and be capable of adapting to the

needs of future decades.

Applying this mantra to cable management, our specific

area of interest, is easy. All new and refurbished schools,

colleges, hospitals and other healthcare infrastructure

require the very best in ICT (information and

communication technology) provision. For example,

classrooms no longer have blackboards – teachers and

pupils use interactive electronic whiteboards, along with

laptops and other internet-enabled devices. This creates a

need for effective and safe delivery/management of

power and data cables.

As a cable management systems supplier we are

obviously only involved later on in the build schedule.

And, as specifications and fit-out requirements have

become more hi-tech, so the demands on trunking

systems have changed and our range of solutions has

evolved over the 25 or so years we’ve worked with the

education and health sectors.

A good example of this is modular wiring systems, such

as Marshall-Tufflex’s MT32 sytem. Prefabrication has been

a buzzword for a number of years, and modular wiring

systems deliver just this for specifiers and installers. They

are not a trunking solution but work in conjunction with

trunking to deliver a super fast installation that can be

reconfigured at a later date. These factory-tested ‘plug-

and-play’ power connection solutions are a quick and

easy way of taking power from source and delivering it to

final outlets via plug-in connectors. Modular wiring

delivers tool-free, fast-track installation of complete

CABLE MANAGEMENT

cabling runs. There is no on-site wiring required, allowing

installers to simply click together, circuit test and sign-off.

Installation times can be reduced by up to 80%, with

overall cost savings of up to 50% possible. The best

systems are plug and play – keyed connectors do not

allow it to be installed incorrectly, increasing the safety

factor for both contractors and clients. What’s more the

systems can be reconfigured (for example during office

moves), stripped out (during refurbishments) and re-used.

Modular wiring is therefore perfect for future-proofing

projects – install it in an ICT suite today to feed power to,

for example, 15 computers and when 15 become 25

computers, simply unclip the front cover of the trunking,

‘plug-in’ extra lengths of MT32 in order to add new

sockets, circuit test and sign off. Not only does this negate

the need for a major re-wiring exercise, MT32 can reduce

installation times, achieving double the workload with the

same resource.

Purr-fect choiceFuture-proofing data installations can also be achieved

through the correct specification of cable containment.

Historically local area networks were designed with a

Category 3 circuit for voice transmission and a Category 5

or 5e circuit for data. This configuration eventually failed

to cope with rapidly increasing data rates/networked

devices and was replaced with Cat 5e throughout. Now

the industry is looking to Cat 6 and above to deliver

performance required now or in the future.

However, as data wiring develops to handle larger

amounts of information and networked devices, it

becomes dimensionally larger, creating problems for

designers and installers, particularly when cabling needs

feeding around corners. To give an example, Cat 6

cabling is approximately 5-6mm in diameter, with ‘data

bends’ of up to 25-50mm (depending on cable

specification) required within cable containment systems

to channel it around corners. Cat 7 cabling is about

10mm in diameter requiring a bend radius of 40mm

minimum and poses real issues when it comes to cable

containment. Sounds innocuous enough, but if more

space is not allowed for these ‘data bends’ and the cable

is fed through a standard radius bend in a cable

containment system problems may arise – subjecting Cat

6 or higher cabling to standard bends can ‘pinch’ or

compress the copper data cables, resulting in a drop in

performance – data may be lost in transmission or

streaming quality affected.

Marshall-Tufflex has invested heavily in developing

cable management systems appropriate for use with Cat

6 cabling. Design engineers looking for bend radius of

25mm or 50mm can consider its Sterling range or its

tamper-proof, all-curved profile, Odyssey system.

Future-proofing installations by installing Cat 6

compliant trunking is a major consideration where

networks will be required to handle large volumes of

devices and information. But what other factors should

design and build specialist be considering when

considering cable management solutions for schools?

Function or formHow about both? The latest generation of trunking can

offer great performance coupled with architect-

pleasing curves, so there is no need to compromise on

design. Curved profile trunking also offers another

huge advantage – it simply cannot be used as a shelf.

Not only does this keep classrooms, corridors etc clear

of clutter and litter, it also aids cleaning since the PVC-

U can be easily wiped clean, a major benefit when

specified in sensitive environments such as schools. The

curved profiles are also completely in keeping with the

design of many new schools, with architects utilising

softer lines to make learning environments more

appealing.

And curves don’t just apply to the trunking profile –

Marshall-Tufflex offers a special service to adapt its

systems or pre-fabricate specialised and bespoke

solutions. This means trunking can be curved off-site in

order to fit snugly against a curved wall.

Material choiceTrunking is usually steel, aluminium or PVC-U, a proven

material that it is easier and quicker to install than

metal systems. Not only does it reduce time on site for

contractors and maintenance staff, it also reduces

facility down time during refurbishments. In addition,

PVC-U systems can be supplied with EMC screening – a

copper spray is applied to the inside of the trunking,

creating a Faraday Cage to exclude electrostatic

interference, delivering the required screening without

compromising trunking capacity. PVC-U is also tough

and hard-wearing, making it a good choice for areas

where hard knocks are inevitable. When specifying

PVC-U trunking check that it complies with British

Standards BS4678 & BS EN 50086 which govern

impact strength.

Bio-logicalCable containment manufactured from PVC-U can be

impregnated with an antimicrobial agent to help

prevent the spread of infections such as MRSA, E-Coli,

Salmonella and a range of everyday bugs. Antimicrobial

trunking systems come in two variants:

▲ The silver-based formulation is added to the PVC-U

during manufacture, ensuring that it is evenly

distributed throughout the product. Should the

trunking get scratched, the active agent continues to

do its job. This is the system used by Marshall-

Tufflex.

▲ The silver-based formulation is applied to the

surface of the cable containment. However, once

this coating is scratched, germs can penetrate the

surface layer of these products and breed

unchecked.

Specifiers should give priority consideration to

trunking with the antimicrobial agent integral to the

product to ensures maximum performance throughout

the lifetime of the trunking. Those thinking of using an

antimicrobial system should confirm it is registered with

the Environmental Protection Agency and compliant

with the European Biocidal Products Directive.

ConclusionCorrectly specified cable management systems have the

ability to neatly and efficiently deliver power and data

with the minimum fuss and little to no maintenance,

particularly when manufactured and supplied by a

specialist producer with in-depth experience of the PFI

sector. As demonstrated, there are a number of

important factors to be considered when specification

decisions are being made – get those decisions right

and the client will have a power and data delivery

system that delivers now and many years into the

future.

SWITCHGEAR

Apart from compact

size, vacuum circuit-

breakers offer

excellent electrical

performance

VACUUM interruption is a proven technology, introduced

more than 40 years ago. Arc interruption takes place in a

vacuum ‘bottle’. Vacuum interrupters do not require costly

leakage monitoring equipment. Electrical performance is

comparable and, at times, better than SF6 switchgear. While

capital cost is slightly higher, total life-cycle cost is lower due

to the lower maintenance costs. All materials can be recycled

at end of life.

Continuous development has seen the size of a 15kV

vacuum interrupter bottle come down from180mm diameter

in 1967 to 50mm today. Meanwhile modern sealing

techniques ensure that units retain their vacuum for more

than 25 years. On the rare occasions when leaks do occur,

they normally manifest themselves early in life; so rigorous

production testing helps identify such leaks before units

reach the field. Any leaks are, of course, completely harmless

to the environment.

Vacuum circuit-breakers are suitable for a wide range of

medium voltage switching applications including transformer

secondary protection, capacitor switching and motor

switching. They are used by utilities for ring main units and

MV switchboards in the range 3kV to 36kV. They are suitable

for current ratings from 100A to more than 4,000A and fault

levels from 6kA to 63kA.

Apart from compact size, vacuum circuit-breakers offer

excellent electrical performance. They will normally withstand

a rated a.c. power frequency withstand voltage (an

overvoltage due to power system switching operations) of 2-4

times normal operating voltage. Rated lightning impulse

withstand is 4-12 times normal operating voltage. However,

in normal service the breaker contacts are closed so lightning

overvoltages are mostly seen by the line-to-earth or line-to-

line insulation; in the rare event of a lightning impulse

appearing across the open contacts of the vacuum interrupter,

the current will be quickly broken. Under similar conditions an

SF6 puffer-type circuit-breaker, air circuit-breaker or minimum

oil circuit-breaker would probably explode.

An interesting characteristic of the vacuum circuit-breaker

is self-conditioning of the contacts. Rough spots that can

occur on the contact surfaces are smoothed out by the

discharge when the contacts are opened on-load.

Vacuum interrupters offer exceptional performance under

load switching conditions, far exceeding the mechanical life

of any circuit-breakers and reclosers of which they form a

part. Consequently they are used in railway switching

applications where electrical and mechanical life in excess of

250,000 operations is required. They are also suited to motor

switching duties in excess of one million operations, arc

furnace switching and capacitor switching. Contact resistance

remains low throughout life because contact erosion only

occurs at the cathode and eroded material is deposited

uniformly on the anode; the contacts act randomly as

cathode and anode so the effect is evened out. In SF6 circuit-

breakers, contact resistance increases during life.

THIS IS BASED ON THE PREMISE THERE IS NO VIABLEALTERNATIVE. HOWEVER, IN THE RANGE 1-52KV THERE IS A PERFECTLYVIABLE OPTION IN THE FORM OF VACUUM SWITCHGEAR WITH SOLIDDIELECTRIC INSULATION.

IT ISBEING USED INCREASINGLY BY UTILITIES IN EUROPE FOR MEDIUMVOLTAGE (1-52KV) APPLICATIONS SAY W PORTE AND GC SCHOONENBERGFROM EATON, IN THE SECOND INSTALMENT OF THIS TWO-PART ARTICLE *THE FIRST PART OF THIS ARTICLE CAN BE FOUND AT WWW.ELECTRICALREVIEW.CO.UK

14 Electrical Review November 2009

Vacuum interrupters are constructed from materials that can

be recovered and recycled at the end of life. They do not

contain greenhouse gases; nor do they present potential health

hazards due to the products of decomposition. No special

precautions are necessary to protect the environment from the

results of leaks or during disposal.

The compact size of modern vacuum insulator bottles

means special measures are necessary to improve insulation

levels. A 150mm ceramic length will only have a basic

insulation level (BIL) of 125kV in air. For this reason insulators

may be immersed in a dielectric medium such as oil or SF6

gas to raise the BIL to 170kV. Oil is being phased out because

of the fire risk, so SF6 insulation is favoured by many

manufacturers.

However, an alternative approach is to enclose the vacuum

interrupter in a potting compound such as polyurethane or

epoxy. In some cases an epoxy insulator with a contoured

profile, similar to the ‘sheds’ used on overhead line insulators, is

used to increase creep distances. This is especially valuable

when the equipment is used in industrial environments

involving heavy atmospheric pollution or condensation. In

some cases the entire interrupter and associated busbar are

enclosed in solid insulation.

Modern vacuum switchgear with solid dielectric insulation is

comparable in size to the SF6 gas insulated equivalent. The

circuit-breaker assembly can operate in a normal enclosure

with no special sealing or gas filling, and there is no need for

costly monitoring equipment. Maintenance is negligible and life

can be expected to be 30 years or more.

Total cost of ownershipWhile the unit cost for gas insulated switchgear is lower than

for the solid insulated switchgear described above, total cost of

ownership is much higher for the GIS equipment. The

specialist nature of the pressure checks needed by GIS

equipment means that trained personnel with specialist

equipment will have to carry out the work. One estimate has

put the annual cost of this maintenance as 9% of the

equipment value per year. This does not include any other

safety and insurance costs.

Disposal costs for GIS equipment at end of life are difficult to

quantify. Recycling of parts and by-products is not practicable

and dismantling, transport and disposal costs will be high. In

contrast the solid-insulated equipment is fully compliant with

ISO 14001, covering environmental management systems and

standards. All parts are capable of being recycled.

ConclusionThere is no justification – environmentally, technically or

financially - for using SF6 gas-insulated switchgear for circuit-

breakers and ring main units up to 52kV. In fact vacuum

interrupters up to 145kV are now in service. However, solid

insulation has yet to catch up with this.

DRIVES AND CONTROLS

GLOBAL greenhouse gas emissions are down 3% on last

year, according to the International Energy Agency.

Unfortunately this is not a massive triumph of green

technologies, but is a reflection of the reduced economic

activity brought about by the worldwide recession.

This has given us a bit of a breathing space in which to

reassess our position in regards to global warming. And

we must be careful not to waste this advantage with a

headlong rush to rebuild things as they were.

Instead we need to take time to work out how we can

do things better this time around. We won't get everything

right, but the world needs to change and electrical

engineers can play a vitally important part in building a

better tomorrow.

In a recession there is simply less work available, so

businesses have to make financial savings. Ten or twenty

years ago this tended to mean job cuts; but modern

businesses run pretty lean and recognise that losing people

also means losing skills that may never be replaced. So

savings need to be found elsewhere.

A big cost for most businesses is energy bills - and these

can be controlled!

Here we have a conjunction of an economic need to cut

power bills and a social drive to become more energy

efficient. Good housekeeping – switch things off, turning

things down, checking the insulation – will pay worthwhile

dividends. But the real benefits come with a long term

commitment to control energy usage (and therefore costs)

on an on-going basis.

Probably the technology with the best energy saving

potential is variable speed inverter drives, which are fitted

to electric motors to control speed, and therefore costs.

Electrical engineers have long known the basic rule that the

energy saving is proportional to the cube of the speed

reduction, which means that a small reduction in speed will

give a huge reduction in running costs and energy used.

Traditionally, financial managers have often only looked at

initial capital outlay, not recognising the short payback and

significant savings that can be achieved with such systems.

A climate of changeHowever with climate change now so high on the agenda,

traditional thinking is being turned on its head.

Governments around the world are introducing laws and

guidelines to promote the adoption of inverters.

One clear example of this in the UK is the new Part L of

the Building Regulations, which recommends inverters

should be fitted to all pump and fan motors over a

moderate 1.1kW. Doing this will improve the efficiency

grade of the building and actually improve the value of

the building asset.

Don't waste the hard THE ELECTRICAL INDUSTRY COULD BE AT THE FOREFRONT OF HELPINGORGANISATIONS RECOVER FROM THE ECONOMIC DOWNTURN, BYINSTALLING ENERGY SAVING EQUIPMENT AND GREEN TECHNOLOGIESTHAT WILL ALSO HELP WITH CARBON REDUCTION REQUIREMENTS. SOSAYS JEFF WHITING OF MITSUBISHI ELECTRIC

Jeff Whiting

16 Electrical Review November 2009

Drives are at the very forefrontof energy saving programes

throughout industry

A modern medium sized office building, for instance will have literally

hundreds of motors tucked away behind access panels. Every fan has its

own motor; pumps in the air conditioning, heating and water supplies are

often motor driven: high powered extracts in the kitchens - motors are

everywhere.

Let's look at a typical example. A 100kW motor is not a cheap thing to

buy. There are more costs in installing and commissioning it. Then there is

regular maintenance. And, not least, it will be running up the energy bill

every time it is used. And the last cost is by far the largest one!

Such a motor will have a typical working life of 15 years. And it is of such

a size it is likely to be assigned a duty where it is running 24/7. In this case

its total energy consumption would work out at £75,000 per year.

Interestingly, most systems have some sort of mechanical damping

device to control or limit flow as motor systems are generally sized for

‘worse case plus’ conditions they are never required to operate at. Include

an inverter and you can control the speed thereby reducing the flow, but

with the added benefit of significantly reducing the power requirements.

Usually you would expect to find the motor never needs to run at more

that 80-90% top speed. Often you can run it at a far lower speed, say 25-

50%, and you could turn it right down or right off at weekends, bank

holidays and possibly other times too.

Do this and energy consumption would reduce significantly, possibly 50-

70% – that is to say a saving of maybe £50,000 each and every year of its

operational life. An inverter can be programmed to make all these speed

changes automatically.

But what of the initial capital outlay? Well most retrofit inverter

installations will pay for themselves in 12-18months, fast enough to

impress even the grumpiest of accountants. Further, there are now grants

available and financial plans that mean you pay for the inverter as you

achieve your energy savings.

Inverter installation costs are, naturally, far less if they are designed into

new build projects, and the payback time is therefore reduced significantly.

While there are many motors in an office, there are significantly more in

a factory with lots of production plant or in a hospital with all its high tech

medial apparatus, or in a leisure facility housing exercise equipment,

catering, computer games etc.

In fact, the manufacturing and production industries are by far the

biggest users of energy, consuming about 40% of the total generation

capacity. 70% of this figure (i.e. 30% of the total) is used to run electric

motors, of which only 17% are fitted with energy saving inverters.

And while you may think that 17% is a poor, it is streets ahead of the

figure for inverter take up by other sectors of the economy.

reason government guidelines always fought shy of

drives, not recommending them with the enthusiasm that

might have been expected. But now the tide has turned

In a recent revison of the McKinsey report, the

management consultants re-aligned the inclusion of

inverters as being one of the most cost effective

measures, creating a big impact on CO2 levels and global

warming.

The government is advised by McKinsey & Company,

the international management consultants, who for some

reason did not acknowledge the full carbon and money

saving potential of drives until their most recent

publication.

Their initial report: Pathways to a low carbon

economy: Version of the global greenhouse gas cost

abatement curve, includes the McKinsey greenhouse gas

abatement cost curve.

A cost curve is a typical tool of management

consultants – and let it be said – they are often very

useful, condensing complex and multi-dimensional

information into a simple two-axis graph. The problem

with cost curves is users know how difficult they are to

compile and that management consultants charge a lot

for them, so they are pre-disposed to trust them and

therefore use them blindly without questioning their

accuracy.

Unfortunately Version 1 of the McKinsey curve

presented variable speed inverter drives as an energy

saving solution with significant cost! A new Version 2

curve, now in circulation puts drives right at the top of

the energy saving ranking, recognizing the high level of

savings that are achieved with such systems. The savings

are only bettered only by a wholesale switch to LED

lighting and thermal insulation of commercial buildings.

Drives are seen as greener than other industrial efficiency

improvements, electricity from landfill gas, biofuels,

geothermal and next generation hydroelectricity schemes.

Let's look at some details of the report. The analysis

finds that if no attempt to curb emission is made, they

will grow by about 40% by 2030. There is potential, if

everyone pulls together, to turn this around to a 35%

reduction. This would cost about £200bn annually, or 1%

of global GDP, and would hold global warming to just

under 2°C, a critical figure if icecap melting and desert

growth are to be contained.

The International Energy Agency's report suggests the

recent recession has bought us a couple of years on

these figures. Unhappily, I would predict at least two

more recessions before 2030, which might win us

another six years (thereby giving us time for yet another

recession and three more years).

The report goes on to define four categories of

abatement opportunities: energy efficiency, low carbon

energy supply, terrestrial carbon (agriculture, forestry),

and behavioural change. Of these energy efficiency has

the most promise; it could account for about a third of all

potential savings, uses mainly proven technologies and

does not rely on changing human behavior.

McKinsey looked at carbon reduction on a global scale,

but this is not a scale familiar to most working engineers.

They look at a rather smaller world; refurbishing some

building controls, a single production plant or design of a

machine.

Until recently it was unheard of that customers or

bosses asked for a reduced carbon footprint. But they are

now being forced to do so (although it is often presented

as a financial saving).

Electrical engineers will be the ones who lead the

widespread adoption of inverters and other green

technologies. And now with business minds so focused

on cost control is a good time to get a firm foothold in

what will become a staple of the sector.

In terms of energy

and the

environment, we

have found modern

manufacturers have

many things on

their mind

WITH MANY FACTORS making up the full sustainability

picture- from raw materials extraction to final delivered

product and beyond that, to recycling or disposal of the

product and or its packaging – come many opportunities to

improve efficiency at every step and to improve productivity,

safety and brand reputation at the same time.

Sustainable production must balance environmental and

social performance factors in addition to those for business

performance. Sustainability is not simply about energy, though

of course the reduction of energy consumption throughout

the process should form an integral and measurable part of

any improvements to the sustainability process, there are

several other factors to consider. Emissions, materials, waste

and safety are elements that can each be looked at in

exhaustive detail, not to mention labour practices and product

responsibility.

In 2005, Julian Allwood, from the Institute for

Manufacturing, University of Cambridge, defined sustainable

manufacturing as: “using technologies to transform materials

without emission of greenhouse gases, use of non-renewable

or toxic materials or generation of waste, while optimising

yield and supply chain integrity.” Manufacturers have since

been making clear demands of automation solution providers

like us.

In terms of energy and the environment, we have found

modern manufacturers have many things on their minds. The

list includes energy costs and supply volatility, raw material

and water costs, renewable energy alternatives, recovery and

recycling, raw material reduction, emissions monitoring and

reduction, responsible product and packaging design, carbon

foot-printing and consumer and community imperatives.

Fortunately, this means there is plenty of scope to make

continuous improvements to every step of the supply and

production chain as they progress towards a sustainable

manufacturing future.

Economically, manufacturers are calling out for three main

solutions to stay profitable and competitive while moving

towards sustainable manufacturing targets. First, improved

automation integration and consequent lower cost of

ownership – with more and more automation required to

remain competitive, the initial outlay must be economic and

also integrate where possible with existing equipment and

future procurements. Second, maximum manufacturing

efficiencies must be achieved – increasing throughput and

reducing waste and downtime are vital to achieving both

ecological improvements and increasing production. And

third, of real importance is simplification of the information

flow through improvement of the integration of business to

manufacturing systems- vital for minute, real-time control,

analysis and reporting.

Information as a core component of sustainableproduction solutions.Taking steps to improve performance in these areas is, initially

and progressively, highly dependent on information gathering

as the foundation of solutions management. In terms of

utilities, for example, accurate monitoring of the supply chain,

both upstream and downstream, to determine usage is a key

factor in managing the improvement of efficiency. Within the

plant, modifications to optimise WAGES (Water, Air, Gas,

Electricity, & Steam) and increase the ratio of productivity to

resource used are also highly dependent on the speed and

flow of accurate information from the plant floor to the

management floor and decision makers.

Looking ahead, in some areas of the world the most

significant commodity, particularly in the food and beverage

industry, is, of course, water. The risks of dependence on

water play out both locally and regionally. It is effective water

availability that matters, for example, the right amount of

water, at the right quality, at the right time and at the right

place. In addition to these local production issues companies

have global exposures to water scarcity through their supply

chains. The case for efficient management of resources here is

compelling and will surely become stronger over time.

Fundamental optimisations such as replacing boilers and

motors with more efficient models can also have a huge

impact to reduce utilities usage. It goes without saying such

measures are more often of economic benefit in the medium to

long term and can help reduce vulnerability to fluctuating costs

of energy supply. In this way it can clearly be seen that one of

the key drivers for sustainable manufacturing, that of

environmental legislative direction, both published and

foreseeable, if handled positively and proactively, using simple,

well thought through techniques and good solution

management, can bring clear economic and competitive

advantages to the manufacturer. For UK manufacturing this

reduction of overheads is clearly of significant importance to the

continued viability of UK based plants as opposed to those

based in emerging industrial nations.

Brand equity and the information consumer.Similarly, brand reputation is a cornerstone of the foundation for

sustainable manufacturing. The drivers towards sustainable

manufacturing are reflective of society’s developing attitude

towards the environment and an increasing sense of personal

responsibility taken by consumers, and impressed upon

businesses when they act as a consumer. Manufacturers are

increasingly seen as, and encouraged to be, responsible for the

entire ‘chain of custody’. In the information age the consumer

demands that, before they part with their money, manufacturers

can show them that they source and produce the ingredients,

packaging and product in a safe, efficient and ethical way. Where

they can make a choice between a manufacturer that can show

this and a manufacturer that can’t, or hasn’t tried to, they will

increasingly take the greener option, often even though it may

be more expensive. This attitude is supported by initiatives to

label products with internationally recognised standards that

prove the manufacturer has shown due diligence or taken

proactive steps in these areas. For example, moves towards

publishing the carbon footprint of a product on its label. Clearly

good practice can become a selling point in itself, but perhaps

the point is better made by noting the potential damage that can

be sustained to a brand when things go wrong.

At this point safety becomes an integral part of the process

and can further be used to drive productivity. In our experience,

we have seen that improving safety standards tends to improve

production output through reduced downtime as well as

providing recall ability through tracking and traceability. These

are important factors in preventing potentially brand damaging

goods being produced in the first place, or reaching the

consumer when they are. Using technology to ‘track and trace’

and record all resources used and actions taken during

production gives the manufacturer real-time knowledge of all

raw materials, people, equipment and utilities for each lot. Full

supply chain traceability also supports carbon footprint

awareness initiatives. Action to install safety systems to prevent

accidents and thus reduce downtime as well as improve the

safety record may be simpler, quicker and more cost effective

than many manufacturers realize and all successful measures

support and improve the highly important intangible asset of

brand equity and should be a driver of the move towards

sustainable manufacturing.

Sustainable manufacturing can become a virtuous circle of

improvement when the many forces at work that shape it are

considered rationally and improvement is made continuously

through effective solutions management. Importantly, the same

improvements for the environment, for safety and for brand

equity in a leaner, greener manufacturing environment can be

harnessed to improve competitiveness and productivity.

FACTORY AUTOMATION

AS PART of a complete overhaul and

modernisation of its UK supply chain, PZ Cussons

decided to take advantage of the control and

visibility capabilities offered by a modern process-

capable automation infrastructure. While

establishing the justification for a new UK

manufacturing facility, the company realised much

of its existing process equipment at its old site was

not up to the demands of a modern manufacturing

environment. This is one of the reasons it chose to

employ the very latest the industry had to offer

from Rockwell Automation and its alliance partner

Endress+Hauser. Not only was the solution all

based on the ISA S-88 standard, utilising

networked instrumentation and routing valves, but

the Rockwell Automation Integrated Architecture

meant a common software environment and

scalability made installation and cross-line

migration incredibly straightforward.

Starting from a 'clean slate', PZ Cussons

recognised many areas where savings could be

made and unnecessary costs removed. It also

wanted to adopt leaner manufacturing procedures

making further savings in stock holding and

deliveries. The primary challenge was to obtain

visibility of all steps of the process and to keep all

parameters within operational tolerances. This

required extremely accurate batching, mixing and

metering systems, which could not only

communicate with each other, but also with the

master control system within the offices and

external suppliers via a secure extranet.

An entirely new processing and production

operation was developed, controlled by equipment

engineered, supplied and improved by services

from Rockwell Automation, along with instruments

and fieldbus networks engineered, designed and

commissioned by Endress+Hauser. The

implementation of the project made full use of the

flexibility, the improved process and diagnostic

data that the fieldbus devices provide. This has

given PZ Cussons a level of process visibility and

control far beyond what it had in its older plant.

The new approach is helping it to attain many of

the savings it envisaged, while also removing many

of the process variables which introduced

unwanted costs.

By measuring and automating virtually every

step of the recipe creation, mixing, processing and

packaging lines, the total solution supplied has had

a significant impact. Not only has the control

system provided the required production volumes,

but with the seamless integration of the field

devices, providing validated accuracy the quality

targets have also been met. The savings have been

such that the company is vindicated in its decision

not to move manufacturing to alternative locations

outside of the UK.

According to Andy Ellams, process development

manager at PZ Cussons: "We had a very clear view

of what we wanted – a distributed control system

which runs off a set of servers integrated into our

shared with our office systems traffic."

The field instrumentation can be maintained and

configured from a central location using the FDT/DTM

capabilities of Endress+Hauser’s FieldCare, the fieldbus

networks also facilitate central monitoring and analysis of

communication traffic.

This completes the integration from the control system to

the field device providing validation of measured variables

and consistent device maintenance.

PZ Cussons has effectively been able to deskill some

processes that took operators many years to learn. Even then,

each operator had their own way of doing things on each of

the machines, which lead to some of the process variability.

Labour in one area has been reduced from 16 people on a

four-shift pattern to just one person who only needs to visit

the section once a day. Some of these roles have been

redeployed elsewhere in the factory.

With the old approach, all of the recipes were hard coded

into the PLCs so there was no easy way to test new recipes

and mixes without a significant re-coding exercise. Rockwell

Automation's technology has allowed the company to pilot

test new recipes on a small scale prior to mass production.

Previously, there was a need for specialist operators, but due

to the scalability and portability of the software, any operator

can now run any line. Operators are now much more multi-

skilled – adding value to the areas where their intervention

really counts.

Ellams concludes: "First-time passes are now becoming the

norm. The quality standards we are seeing are very high with

little or no tweaking required. We often go weeks without any

production issues." Overall, the plant is experiencing reduced

downtime, greater accuracy and shorter batch times, which, in

turn, is also saving energy and shortening time to market.”

LIGHTNING PROTECTION

The risk assessments

are extremely time

consuming but

intrinsic to the

whole process

THE PAST YEAR has been a huge learning curve for the

entire industry. Literally thousands of operatives, apprentices

and consultants now have to possess some, if not full,

comprehension of this new standard. Its arrival has changed

how the industry operates forever! For the past three years a

dedicated Atlas team has worked tirelessly to disseminate

and educate the industry about the fundamental changes,

additions and implications of BS EN 62305. What has

become apparent is Atlas members who undertook the

special training workshops are a cut above the rest.

The complex risk assessments that are now compulsory

under the new standard are extremely time consuming but

intrinsic to the whole process. However, several members

have reported many contractors still appear to be unaware

that these risk assessments are a mandatory requirement

and are therefore still accepting quotations from non Atlas

members who are not working to the new standard. Colin

Clinkard from Best said: “We are extremely happy our LC

designers and estimators have passed the Atlas accreditation,

however there still needs to be a huge push to ensure that

main contractors understand the repercussions of not using a

BS EN 62305 accredited lightning protection company.”

This point is further highlighted by another Atlas member,

Edward Wilson & Co, who has found many contractors and

architects are still requesting quotations from the company

based on the old BS 6651. In the current economic climate,

contractors are understandably looking for the best price.

This, coupled with their lack of knowledge on the extreme

differences between the old and new standards means that

they are often commissioning unsuitable work that is not

compliant. Atlas members are dedicating a lot of time in an

attempt to educate the contractors they work with about the

BS EN 62305, and it is beginning to have a positive effect.

However, with approximately two thirds of contractors and

architects clearly not understanding the new standard, it is

very frustrating and inconvenient to have to teach them what

BS EN 62305 is all about every time they tender for new

business.

Although there are inevitably issues surrounding BS EN

62305, all Atlas members believe the new standard is a

positive thing for the industry. Atlas member, John Ashmore

from Protectis said: “The next step must be to set up training

workshops for engineers and architects. It’s as simple as this;

unless they understand how the new standard works and

the huge benefits that it gives them, inadequate lightning

protection will continue to be offered to clients who will then

find that their buildings are non-compliant.”

Fellow member, Andy Richie agrees. His company,

Lightning Protection Services has noticed a lot of large

projects that were originally planned before the new

standard’s implementation are still being built now with out-

of-date protection. Jason Harfield of Orion has also observed

the new standard is being ignored with specified separation

distances not being adhered to. Orion has put all their

employees through the Atlas design course for the BS EN

62305 and feel the whole industry must follow suit, if only to

put an end to the ignorance.

Overall, everyone agrees more education on the new

standard needs to be provided to the construction industry as

a whole. Atlas is still the only organisation to offer

comprehensive training. The National Construction College

offers NVQ Level 2 for apprentices but this is only a basic

introduction. Like it or loath it, the arrival of BS EN 62305 has

split the industry. Lightning protection is now recognised as

an extremely skilled profession. The new standard has clearly

started to separate out the professionals from the cowboys!

Ignorance is no DEFENCE!LAST AUGUST SAW THE LONG AWAITED ARRIVAL OF THE NEW BRITISHSTANDARD FOR LIGHTNING PROTECTION, BS EN 62305, REPLACING THENOW OBSOLETE BS 6651.

LIGHTNING PROTECTION

SCOUT MOOR WIND FARM, (the largest onshore wind farm

in England), consists of 26 wind turbines situated on the

moors of North West England between Rawtenstall and

Rochdale with the Rossendale Way running through the

heart of the site. When running at full capacity, the farm

generates 65MW of electricity, providing enough power to

meet the average needs of 40,000 homes. To ensure

continuous and reliable electricity generation in such an

exposed location, the site required the installation of

extensive earthing and lightning protection systems to

protect it from the potentially devastating effects of a

lightning strike. McNicholas awarded the contract to Omega

Red Group – one of the UK market leaders in earthing and

lightning protection.

In the early stages of the project, Omega personnel

conducted soil resistivity surveys at each of the turbine

locations, and at the substation situated approximately a

mile away, to enable a detailed design to be undertaken.

This would not only ensure the safety of the structures

themselves, but would also safeguard the general public

against the hazardous touch, step and transfer voltages that

can occur when lightning strikes or when power system

faults occur.

The remote location of the wind farm combined with

unpredictable and often inclement weather conditions

(including thick fog, snow, ice, torrential rain and gale force

winds) provided additional challenges throughout the

project. During the installation, a few potential issues were

encountered in obtaining the requisite resistance values at

some of the turbine locations, largely due to the ground

conditions varying from marsh bogs to solid rock. However,

the proactive approach and technical expertise of Omega’s

onsite engineers and operatives soon ensured that these

issues were resolved without compromising the

construction programme.

At the end of the construction and installation phase,

Omega was further tasked with carrying out the overall test

of the earthing and lightning protection systems on both

the substation and turbine sites to confirm their compliance

with all statutory requirements. Due to the large footprint of

the site, the test leads were required to be run out in excess

of 2 kilometres – including across a waterfall - to obtain an

accurate set of test results - just another small challenge for

the Omega engineers to overcome!

Because climate change is now widely recognised as

one of the most important global issues, and reducing the

amount of greenhouse gas emissions is a vital element in

limiting the effects of climate change, Omega is committed

to working within the renewable energy market, using its

expertise, technical competence and extensive experience

to overcome the very specific challenges this market

presents.

“The sheer size of wind turbines along with the isolated

locations upon which they are constructed renders them

vulnerable to lightning strikes. Without adequate earthing

and lightning protection systems they are more likely to

suffer the detrimental effects of a lightning strike. We are

extremely happy to be involved in the success of wind

farms across the UK and to use our expertise in the support

of this growing, environmentally- friendly industry”.

FOR ALMOST 35 years R. C. Cutting & Co. has been involved

with the All England Lawn Tennis Club (AELTC) both in new

installations and the ongoing maintenance surrounding

their world famous Championship in June each year.

Most recently have been the challenging works to Centre

Court, where a new retractable roof has been incorporated

over a three year construction period. The continued use of

the playing surface during the Championships was always a

factor and the re-development works had to be scheduled

around this.

Now complete, the roof can be closed and the

temperature and humidity controlled dependant on the

number of spectators, thus ensuring that play can continue

whatever the weather.

For those that remember, the 1996 Championship was

delayed hugely by bad weather and the crowds were

frustrated by the conditions and delays. .

The lightning protection system, originally installed by

Cuttings in 1992, has been enhanced and the steel

supporting structure of the new retractable roof was

incorporated giving particular regard to the many

moving parts!

POWER GENERATION

THERE IS though a great deal of variation within the power

industry, and outside it, as to what exactly should be included

under the idea of a smart grid. Ask a room full of utility

professionals to define the term and you're likely to get a

wide range of answers. But most probably the discussion will

focus on FACTS (Flexible AC Transmission Systems), WAMS

(Wide Area Monitoring Systems) and HVDC (High Voltage

Direct Current) technologies. These are of course very

important transmission technologies that are already starting

to play a significant global role in the development of smart

transmission grids.

Ask a room full of consumers, and the talk will probably be

about smart meters. Personally though, I am coming to the

conclusion the ‘killer’ element of the smart grid will be in

between these two extremes – at the distribution network

level. Distribution networks may well be the key to help

manage the impact of the variable nature of generation from

large volumes of wind energy coupled with the dynamic

requirements of customer electricity demands.

The increased reliance on an inherently variable source of

generation will pose particular challenges in balancing the

grid to maintain the high level of reliability and availability

expected by consumers. This will be especially true on those

days when the weather is cold, and energy demand is high

with the additional risk of widespread low wind speeds

sometimes seen in an average UK winter.

Since the UK currently has very little energy storage

resource, with the notable exception of pumped hydroelectric

schemes such as Dinorwig (providing 1800 MW), there are

two choices. Either we need to invest in expensive fossil-

fuelled plants to act as backup, or we create a smart grid that

can take active, dynamic control of demand, storage and

distributed generation at the distribution network level.

From passive to active distribution networkTo meet this challenge, distribution networks will need to

make a radical change from their traditionally passive format

(ie, planned for particular peak loads and for use as fit-and-

forget networks) to become more active or dynamically

adapting networks in order to manage the increasing

demands placed on them. This will necessarily be a two-way

system where power generated by a multitude of small,

distributed sources (CHP and domestic micro generation etc)

flows into a grid based on a network rather than a

hierarchical structure. Just as the Internet has changed media

from a one-to-many paradigm to a many-to-many

arrangement, so too will the smart grid enable a similar shift

in the flow of electricity. It could also include the connection

of smart white grids in the home, such as washing machines,

refrigerators and freezers, with the possibility that they can be

managed by the local DNO (Distribution Network Operator)

to provide active and reactive load control in the local

network, taking smart metering to a new level of

sophistication.

The smart grid will change the way we look at power

distribution. Technologies are already available in the form of

switchgear, transformers, reactive power compensation

solutions and Scada distribution management systems that

enhance the operation of medium- and low-voltage power

networks. But, as power generation becomes more

distributed, and more power comes from renewable

resources, the distribution grid will need to accommodate

more fluctuations in power quality, as well as two-way power

flow, while also becoming more responsive to changes in

consumer demand. The management of such a complex

system will depend on real-time, secure communications and

highly adaptive control systems. These will provide utilities

TRADITIONALLY, THE UK’S POWER NEEDS HAVE BEEN MET BY LARGE, CENTRALISED

GENERATION UNITS, WITH THE ELECTRICITY THEY PRODUCE TRANSPORTED TO CONSUMERS

and their customers with real-time information from across

the network on the performance of grid installations, power

flow and consumer demand. They will allow intelligent

automated devices to react to imbalances in the system and

also improve asset management by enabling improved

predictive maintenance programs and faster emergency

response times. Improved customer restoration times during

system disturbances and network reconfiguration will

also be a critical aspect of future smart grids. The

incorporation of enterprise-wide information systems

and customer response management tools will

improve utility operations, enabling

better customer relations and

the provision of tailored

services. The introduction

of more intelligent

monitoring systems and

the extension of substation-

and feeder automation in

distribution networks will optimise

operations, bringing improvements in

reliability, availability, security and energy

efficiency.

The way forwardBuilding the next generation of active power delivery

networks requires a mixture of: new technology; existing

technology deployed in new ways; existing asset

infrastructure utilised in an optimum way; and changes in

operating practices by electric utilities. Building on existing

ideas, progress in such a complex, multi-stakeholder research

and development effort requires a collaborative approach

such as in the team-based AuRA-NMS project. Autonomous

Regional Active Network Management Systems (AuRA-NMS)

is a collaborative research and development project,

sponsored by the UK Engineering and Physical Sciences

Research Council (EPSRC), that seeks to demonstrate new

network operation concepts in the UK. In addition to ABB, the

consortium includes two major distribution network

operators (DNOs) and several UK universities.

The goal of AuRA-NMS is to demonstrate the benefits of

active network management using a distributed architecture

integrated into existing control and asset infrastructure. It

includes the use of innovative battery storage to understand

the merits of trading opportunities, the support of constrained

capacity related to overhead lines and cables, and stability

control of the network due to various types of distributed

generation. The project also aims to provide automated

solutions for complicated constraint management.

The network management system controller used in the

project is ABB’s COM 600 series designed to complement the

substation automation and network management systems

already in service by some UK DNOs. The COM 600 supports

the IEC 61850 standard and offers interoperability

and expandability as well as providing a

certain level of legacy protocol support for

the DNOs’ existing feeder automation

devices.

SVC Light with dynamicenergy storageIn coordination with the

AuRA-NMS project, ABB

is working with EDF

Energy Networks on a

collaborative research, development and

demonstration project to install an SVC Light

STATCOM (Static Compensator) with dynamic energy storage

in a grid with a high penetration of wind power. The project is

being financially supported through industry regulator

Ofgem’s Innovation Funding Incentive scheme.

The installation will yield dynamic voltage control in an 11

kV distribution system and at the same time enable dynamic

storage of surplus energy from wind farms, which can be

utilized to level out peaks in grid loading. Using this strategy,

the power harnessed from the wind can be put to more

efficient use than would otherwise be possible. The SVC Light

with dynamic energy storage incorporates a high-tech lithium-

ion (Li-ion) 5.2 kV battery system supplied by Saft that can

deliver 200 kW for an hour and 600 kW for over 15 minutes.

SummaryThe smart grid will not be a revolution. It will be a

transformation of the distribution networks that have served

us for many years into more intelligent, more dynamic and

effective, environmentally sensitive networks to provide for

our future needs. However, if our environmental targets are

to be met this transformation must start now.

IS YOUR CABLE UP TO THE MARK?Draka is spearheading another campaign aimed at highlighting the dangers of installingelectrical cables that fail to comply with the required regulatory standards. This time thecompany is focusing much-needed attention on the absence of cable marking, without whichthere is no means of establishing the cable’s authenticity. In the absence of such marking thereis every probability that the quality and performance of the cable is highly suspect and is froma disreputable supplier.

To help installers, Drakahas published a freely-available pocket guide andhas an explanatory videopresentation on its website. Both are available at www.drakauk.com. The company is alsoinviting anyone who finds unmarked or misleadingly marked cable being installed to send asample to Draka in support of the campaign’s aims to achieve best practice throughout theindustry and eradicate this dangerous and reprehensible practice.

FAST PUSH FIT CONNECTION Flexicon claims its new slimline push fit Flexilok conduit fitting will dramatically speed up installationtimes.

Like the threaded version of Flexilok, you simply push it onto the conduit and then twist to secure.Installers save even more time because the new fitting also features apush fit connection for terminating the conduit into the enclosure orpanel thus eliminating the need for a locknut.

Instead of using a locknut, the design offers a spring-loaded fixingallowing you to simply push the fitting into the hole to secure it. Anadditional O-ring improves the seal between the fitting and theenclosure giving up to an IP66 rating.

You can use push fit Flexilok with fine or coarse pitch nylon,polypropylene and PVC conduits. It can be used with 20mm, 21mm,25mm, 28mm and 34mm conduits with 20mm, 25mm and 32mmknockouts.

TAX RELIEF AVAILABLE FORENERGY-SAVING EQUIPMENTWireless telemetry specialist Radio-Tech hasannounced its energy management system nowqualifies for the Carbon Trust’s Enhanced CapitalAllowance (ECA) scheme under ‘Component-based automatic monitoring and targeting

equipment (AMT)’. The scheme can realise significant financial savings, in both theshort- and long-term, as well as aid improvements in a company’s energy efficiencyand its environmental impact.

An ECA provides 100% tax relief on any investment in energy-saving equipmentin the same tax year as the purchase is made. This means a business payingcorporation tax at 28% will receive 28p tax relief for every £1 invested in energy-saving products. The scheme also reduces the payback period on the initialinvestment.

There are additional and significant long-term savings to be made from such aninvestment. Energy-saving equipment will usually reduce a company’s energy bills,which in turn will reduce the company’s Climate Change Levy.

BLOWN FUSETHIS MONTH, OUR RESIDENT GRUMPY OLD MAN, WRITER ANDINDUSTRY COMMENTATOR JOHN HOUSTON, CONSIDERS THE17TH EDITION WIRING REGULATIONS

WHEN the Duke of Edinburgh some yearsback started a race row by describing someelectrical work as having been installed byIndians when he meant cowboys, he atleast highlighted that sub-standard workremained alive and ill. This month I have toreport I have been the subject of work thathas to have been completed by John Wayne;probably assisted by Gary Cooper and ClintEastwood.

I always knew some of the circuits in myhouse were, well let’s just describe them asesoteric. Having to flick a switch in thegarage in order to turn on the bathroommirror lights was irritating, but somehowamusing at the same time. However, mywife was laying some new insulationmaterials in the loft a few weeks ago whenthere was an almighty flash followed by theinevitable blue acrid smoke. A live wire leftbare was the culprit. Now call me a cynic,but this lead me to consider a little furtherinvestigation.

We found no fewer than 40 junctionboxes in the

loft,

very few of which were employed to splitruns, but rather to create cable lengthsfrom a variety of short cable off cuts. Asmy old pal Nick Luke at WF Electricalwould say “you couldn’t make it up”.Danny our trusted electrical contractortook a look and spent a day tidying up theloft wiring, but we concluded a rewire wasthe only safe option.

Since the house had a very positive fullstructural survey two years ago before webought it, we had decorated every room(except for some ghastly artex ceilings thatwere so outrageous one couldn’t keep one’seyes off them). We shall soon be repeatingthat exercise as we have now lost fourceilings, one floor and had 75 new channelscut into the previously pristine plasterwork.On top of that every previous socket hashad to be filled because under 17th Editionour sockets are all now at least 45cm fromfloor level.

The reason I mention this is while Ialways knew refurbs were clearly a tougherproposition than wiring new builds, untilone experiences the upheaval first handyou really have no idea. Apart from the

obvious mess and decimation to thebuilding’s internal fabric, the

electrician faces constantchallenges both in pulling the

new cables, but also disposingof the old. I really do have amuch greater appreciationfor the skills (and lateralthinking ability) of theelectrical engineer now Ihave witnessed Danny’s

work first hand.It’s not all bad news of course. In

completing the work, we have gained farsuperior thermal insulation (installed whilethe ceilings were down) and increased thenumbers of outlets, lighting circuits and, ofcourse, electrical safety. Our house will alsobe wired to 17th Edition and Part Pcertificated. Danny, being a bright spark(y)also pulled our Cat 6e cables so that wehave no fewer than 27 data points aroundthe house – we can even pipe drossy cableTV to every room and we have a patchpanel fit to run an office block! Our musicand TV speakers are all integrated into thewiring scheme (my wife will so miss all thetrailing cables everywhere), the same is trueof our alarm system and we haven’t had togo to specialist installers to achieve this.

The point I’m really making is today’selectrical engineers can deliver so muchadded value to their installations. Yes therewire was an investment; yes we have hada great deal of making good andredecoration; and yes we did actually moveout for two weeks while all the dust settled.But, Danny’s saved us a fortune in nothaving to employ specialists to install homeentertainment and security systems. In away, it’s probably doubled the value of theinstallation.

There are some things I will miss. It willbe odd not having to visit the garage beforehaving a shave; rummaging in the loft willno longer carry the thrill seeking excitementof not knowing if you’d get out alive; andwe’ll no longer spend hours each daytransfixed, looking up at the artex rolls!
