SUPPORT FOR ENVIRONMENTALENGINEERING COLLEGE BIDThe Joint Contracts Tribunal (JCT) has

given its support to a bid to establish a

University Technical College in Harlow

specialising in environmental

engineering. JCT is a contract drafting

body, with membership which spans

both sides of the construction industry

– four out of every five building

projects in the UK use a JCT form of

contract.

Members include the British

Property Federation, Contractors Legal

Group (made up of National

Federation of Builders (NFB), Civil

Engineering Contractors Association

(CECA), the Scottish Building

Federation (SBF) and the UK

Contractors Group (UKCG)), Local

Government Association, National

Specialist Contractors Council and the

Royal Institute of British Architects.

Peter Hibberd, JCT chairman, said:

“One of Harlow UTC’s key areas of

specialisation will be environmental

engineering: this is an area of

increasing importance for property

and construction, and one that JCT has

been addressing, having been the first

to introduce sustainability provisions

and guidance within its contracts.

“With the upcoming Green Deal

implementation next year, the

industry’s focus will increasingly shift

to retrofitting the existing housing and

commercial property stock in order to

meet the government’s carbon

reduction obligations. Harlow UTC will

help enable the industry to meet

those obligations by providing

students that fulfil the needs of the

work place.”

Earlier this year JCT launched an

education and training initiative, to

ensure everyone entering the industry,

especially at trade level, has an

understanding of contracts,

procurement and the supply chain.

Peter Hibberd continued: “JCT

continues to recognise the importance

of education in construction. Better

understanding of contracts and the

implications actions have along the

supply chain will help the industry

operate more efficiently. JCT will

provide that important link between

the UTC and the construction industry,

helping to bridge the gap between

education and training. It will also

facilitate additional help and support,

and provide guidance to assist the

UTC in providing what the industry

needs.”

Harlow MP, Robert Halfon, said: "I

am very pleased JCT has decided to

support our bid. As one of the

construction industry’s leading

organisations, it is well placed to

provide the guidance and support

needed by this new college.”

Metal halide lamps and

control gear supplied by

Venture Lighting have been

used in the recent

refurbishment of the St

Augustine of Hippo Church,

Edgbaston, Birmingham.

Working in conjunction

with the appointed church

architect, Mark Evans and

electrical installers A J Electrics

(Coleshill), Lighting Dynamics

UK provided a

dimming/lighting control

system which is linked to

detection sensors and wall

mounted control panels at

various points around the

building.

The old linear tungsten

halogen lamps and old style

reflector spotlights were

replaced, and Venture’s 70W

and 150W ceramic single

ended metal halide lamps

were installed, in conjunction

with the company’s Ventronic

low wattage ‘switch dim’

electronic ballasts.

Moog has signed a new five year

contract with SCX Special Projects,

Sheffield, UK to continue its support of

the motion control system for the

Wimbledon Centre Court Retractable

Roof, London until August 2015.

Kevin Mooney, sales manager,

Moog Tewkesbury says: “The roof was

designed with long life and low

maintenance in mind, and one aspect

of the service which we provide is

remote condition monitoring (RCM).

This allows us to monitor and

measure elements such as electric

voltages, currents and positions of the

roof against the parameters set in the

system, all through our web portal.”

Steve Bratt, group CEO the Electrical Contractors’

Association (ECA), has warned the government’s

decision to substantially reduce Feed-In Tariff

subsidies for photovoltaic installations larger than

50kW is a mistake that could dissuade community

projects, including schools and local authorities,

from large scale PV installation that would

generate an income and contribute to UK carbon

reductions.

Bratt said the ECA submitted recommendations

to government saying the downward 'fast track'

revision of FITs should only apply to very large-

scale installations. “The ECA believes the new limit

for lower FITs should have been 150kW, not 50kW.

This would have encouraged community scale

projects, such as solar panels on school and local

authority buildings,” he says. “Now in these cash-

strapped times, communities and civic amenities

have lost a potential revenue stream that could

have reduced their ongoing operating costs. The

ECA notes the government’s reasoning behind

scaling down the tariffs was to prevent very large

installations from diverting cash away from

homeowners, but reducing FITs for installations

under 150kW is a bridge too far.” He added: “Any

significant re-alignment of the tariff away from

smaller-scale PV technology could fundamentally

damage confidence in the renewable sector.”

Bratt warned the move could undermine the

UK’s binding commitment to generate 30% of its

electricity by renewable methods by 2020.

“Currently around 6.7% of UK electricity comes

from renewables. Increasing that to 30% is going to

be that much more challenging if larger buildings,

and others who take notice of renewable price

signals, have less of an incentive to do their part.”

He concluded: “Without doubt, FITs have helped

increase electricity generated from micro-

renewable sources, with homeowners and

businesses taking the opportunity to install

photovoltaic panels because of clear, attractive

price signals. While it seems that there’s not enough

money in the pot for FITs to cover larger

installations such as solar farms, government

should still find a way to stimulate a broad range

of UK PV installation, rather than preside over

some sort of ‘zero sum game’ between business

and domestic PV investment.”

Fourteen British companies are toreceive government support to carryout feasibility studies into thedevelopment of disruptive low carbonvehicle technology.

The £1m funding, from theTechnology Strategy Board, will supportfifteen vehicle-centric studies thatchallenge current conventions. Thestudies will be led by Aeristech, AxonAutomotive, Delta Motorsport,Equipmake, Fusion Innovations, GordonMurray Design, HILTech Developments,Libertine FPE, Nissan MotorManufacturing UK, Ricardo UK (2studies), SAIC Motor UK, Sunamp, TRWConekt and WDL.

With a 10-year history, The Energy Event has grown

to be one of the largest energy exhibitions and

conferences in Europe. Taking place on the 13 – 14

September 2011 at the Birmingham NEC, it is

dedicated solely to energy procurement,

management and efficiency. Supported by some of

the leading industry associations and organisations,

this year’s Energy Event will provide the UK’s largest

client-led seminar programme free of charge and

will address the key issues of energy availability,

affordability and sustainability.

The Energy Event is sponsored by British

Independent Utilities (BIU), a systems-based utility

consultancy that specialises in large multi-location

portfolios, and continues to offer visitors its superb

free seminar programme, giving delegates the

opportunity to hear viewpoints from industry experts

on a range of relevant topics and ensuring they

leave with a sense of how to position their

organisation’s medium term energy strategy to keep

costs low and reduce energy risk.

The Energy Insight ConferenceProviding a forum for debate and discussion of the

biggest issues affecting energy pricing, risk, and the

reduction of carbon, the Energy Insight Conference

brings together leading experts and commentators

in the fields of economics, climate change, energy

policy and security, the nuclear industry, demand

management and carbon reduction.

Day one of the Energy Insight Conference will be

chaired by BBC Radio 4’s Today programme

presenter, John Humphrys, who, during his career as

an award-winning journalist, has worked as a

foreign correspondent, political interviewer, author

and newspaper columnist, and is no stranger to the

global issues debated on energy. Using an informal,

‘chat-show’ format, Humphrys will chair discussions

with key European energy industry figures on topics

such as electricity market reform, energy pricing and

the prospects for nuclear energy.

Also on day one, leading UK business woman,

Karren Brady will join as guest speaker on the topic

of ‘Effecting Change’ in business. As an inspirational

leader and influential business woman with proven

results in revolutionising businesses, Brady is well

placed to deliver this presentation which will look at

how to positively influence organisational change,

beginning at boardroom level, in relation to energy

management.

Guest speaker on day two of the Energy Insight

Conference is Lord Digby Jones, author of the

recently published book Fixing Britain and known as

the ‘face’ of UK business. Lord Jones’ presentation is

entitled ‘Putting Britain at the heart of global

change’ and he has been invited to discuss his

opinions on the need for UK business to promote a

culture of innovation and readiness in order to adapt

for the changes required in the move toward a low-

carbon society.

� ABB’s ZX1.5-R metal-clad, gas-

insulated, medium voltage (MV)

railway switchgear has received a

Certificate of Authority for Product

Trial from the Network Rail

Acceptance Panel (NRAP) for single

and two-phase applications up to

27.5 kV. “Receiving this Certificate of

Authority from Network Rail is a

major boost for the introduction of

our ZX1.5-R switchgear in the UK rail

market as it can now prove its

capability in a practical, operating

network,” said Bryce Denboer, ABB

sector manager – rail. “On successful

completion of a six to 12 month trial

installation, the switchgear will

receive full product approval so that

we can offer it for all appropriate

Network Rail projects.”

� New PV electrical test

instrumentation has been used as

part of the installation of one of the

UK’s largest solar panel systems.

Sundog Energy, a UK provider of

solar photovoltaic (PV) systems,

became the first installer to use the

new Seaward Solar Installation

PV100 tester as part of its contract

with Network Rail to provide a huge

solar PV system on the roof of Kings

Cross Station in London. The PV cells

are integrated into nearly 1,400 glass

laminate units that will form part of

the new glass roofing structure over

the platforms and concourses. The

area of roof that will be covered with

the solar PV glass laminate is

approximately 2,300 square metres.

This project involved the construction of Europe’slargest in-town retail development on a 40 acre sitegrouping 150,000m2 of shops and leisure complex.Located adjacent to the A40 main western access routeto the capital, the contract was awarded to theAustralian developer Westfield in 2005 with the workbeing completed in 2008 at a cost of £1.6 bn

T. Clarke and SSE Contracting were the maincontractors selected by Westfield for the electricalinstallation, which was executed according to the initialdesign put forward by Scottish and Southern Energy(SSE). This strategy enabled Westfield to retainownership of the installation and therefore derive asource of revenue from the electricity distribution.

Electrical distribution solutionIt was Lucy Switchgear’s products that were selectedbecause they represented the best balance of long termreliability, flexibility and overall performance whencompared to the capital outlay. Fuse technology wasspecified as it provided the necessary discriminationand fault limiting characteristics, whilst offering a savingover more complex technological solutions such asMCB/ MCCB. The issue of nuisance tripping was alsoeliminated through the use of fuses. Furthermore, LucySabre and Trident Ring Main Units (RMU) werespecified for the 11kV distribution together with theLucy Indoor Wallboards, Multi Service Distribution

Boards and Heavy Duty Cut Outs installed on the LowVoltage (LV) system.

The main rationale behind Westfield’s choice centredupon SSE’s confidence with the Lucy Switchgear MVand LV distribution switchgear range following their longterm experience with the product portfolio. Crucially,this would also facilitate any future sell-off of theequipment, as the DNO already had substantialamounts of identical products on its asset register.

Unquestionably, this prestigious project oncompletion was of great success and commercialimportance for all concerned, including LucySwitchgear.

Large scale electrical distribution achieved byusing low voltage fuse technologyIn more recent times, the use of fuse technology foroverload and short-circuit protection has largely beenoverlooked by consultants and specifiers in the buildingservices sector in favour of the MCB (miniature circuitbreaker) or MCCB (moulded case circuit breaker).However, the benefits derived from the utilisation offuse technology can be summarised, as follows:

� Total security with guaranteed operation to isolateshort-circuits and overloads

� Simple fuse discrimination rules for ease ofimplementation

� Reduced intrinsically fault limiting I²t “let through”energy to limit damage to electrical equipment

� Long term reliability through no moving parts ormaintenance requirements

� Well-proven technology for your power distributionneeds

� Lower overall cost than other technologies

New fused protection productsSince the completion of the Westfield retaildevelopment, Lucy Switchgear has developed aninnovative range of indoor/ outdoor, LV, fused cabinetsand pillars (known as AcuLok) to complement theexisting range of fused protection devices. AcuLokoffers enhanced safety with its unique fuse carrierdesign and more functionality to cater for therequirements of the Smart Grid era going forward.

So, the next time you are faced with the conundrum– Fuse versus MCB or MCCB, why not discuss yourproject requirements with Lucy Switchgear andbenefit from our proven technology and cost-effective solutions.

Electricity costs are to be slashed and educational

opportunities enhanced at The Business Academy

Bexley, after it was given the green light for a

renewable energy project believed to be the first of

its kind in the country.

The proposed solar photovoltaic (PV) farm will

have a 558.6kW peak capacity and generate around

45% of the electricity used by the Academy, cutting

an estimated £46,790 off its annual £104,700

electricity bill and reducing its carbon footprint by

457 tonnes a year.

The project in Yarnton Way, Thamesmead is

being developed jointly by the Academy and

Dartford-based Enevis, a renewable energy

company with a pedigree in mechanical and

electrical engineering.

The ground-mounted solar farm is also the

largest at any UK school and – following the

government’s Feed-in Tariff support is to be sharply

reduced for schemes larger than 50kW – is likely to

remain the sole installation of this scale to be

attached to an Academy or school.

Included within the proposal is a renewable

energy education centre overlooking the solar

farm for use by pupils from the Academy and

local schools.

OPINION GOSSIP/GOSSAGE

Just a HEATING ENGINEER...Steve Whiteley is a lucky man. Or maybe just a canny one. He has just won a cool £1.4m, with just a £2 horse racing accumula-tor.

A heating engineer in Devon by training, he admits to knowing absolutely zilch about the Sport of Kings. He does notbegin each morning with a detailed assessment of the runners and riders in Sporting Life. Indeed he denies ever having seena copy of the horse racing person’s Bible. He goes to the races maybe once or twice a year. That is all. Last month he went toDevon and Exeter races at Haldon, outside Exeter. He did have a look at the card for the day. He made two selections for eachof the eight races, intending to place £2 to win on each of his choices.

Then, like all good engineers, being a whizz on maths he calculated two times £2 per race was four. Do the same for eightraces, and that ends up as an outlay of £32. So instead he plumped for just a single £2 rollover stake, and just one horse ineach race. He then watched in disbelief as in turn each of his horses romped home. And his initial £2 stake rolled over, to ac-cumulate some 700,000 times. After the victory of his final winner, a 12-1 outsider that had never won a race before, friendSteve was moved to admit: “ I still know nothing about horses. I am just a heating engineer. At least, I was a heating engi-neer. Up until now.” Some guys have all the luck.

When the troubled Sellafield mixed oxide (Mox) plant wasbuilt in the 1990s, at a cost of £1.34 bn, it had to wait severalyears before it was given an operating licence. The principaljustification for awarding that licence in 2001 was the confi-dent belief it would supply hundreds of tonnes of Mox fuel toJapanese reactors. And so make oodles of money for the UK.

In the end, only one Japanese company – Chubu Electric –signed a definite contract. But it operates the Hamoaka plant.And this sits on two major geological faults. In the post-Fukushima antipathy in Japan to any nuclear risks, it is likely tobe forced to close. So bang goes the sole source of funds.

It will cost British taxpayers a further £800m to run the Moxplant for the rest of the decade. And then a further £150m todecommission this expensive heap of radioactive metal. Evenin nuclear terms, compared with uranium ,Mox fuel is astro-nomically expensive.

Thank God Sellafield is way up in remote Cumbria. If such acomplete white elephant had been built anywhere vaguelynear where the TV companies and the chattering classes arebased, it would be notorious as one of the worst wastes ofpublic money on record. Geographical obscurity should not ob-scure the truth.

Sued with great FANFAREGermany’s largest power company, E.On, has announcedwith great fanfare it will sue the German government formaintaining a nuclear tax on spent fuel rods in place,despite ordering it to close all its nuclear power plants. Butwill it?

After all, chancellor Angela Merkel is merely doing whatthe previous Social Democratic government had intendedto do. Which is to close all 17 nuclear plants some timebetween 2020 and 2025.

Of course E.On, and the other three German nucleargenerators, would like to sweat their assets for as long aspossible. But, in practice, the last of them could never havestaggered on much into the 2030s. And certainly all are setto be generating power long after their original officialdesign life, just as is happening with the equivalent agedstations in Britain.

I suspect, in the end, and for all its’ bluster, E.On hasabsolutely no intention of ending up challenging such apopular government decision in the courts. Especially if itcontinue to link the closure decision to the spent fuel rodtax. When the tax was introduced last year, the fourgenerators quietly acquiesced, knowing they had beenonto a good tax-free thing for rather longer than theymight have anticipated. Probably a period of discretesilence from E.On might serve everybody’s interests well.Including its own.

A changed WORLDWhen did I really know the nuclear accident at Fukushima hadchanged the world? When international stars appearing with theworld’s finest opera company, the Metropolitan of New York,refused to fulfil contractual obligations in Japan.

The exquisite Ukranian soprano Anna Netrebko was due toperform in Nagoya and Tokyo. She is best known in the UK for herstunning performance at the Albert Hall proms – she raised theroof at the last night of the 2007 proms. Known as La Bellisima,she explained her walk out with reference to family memberstouched by the 1986 nuclear accident at Chernobyl, in her nativecountry . Whilst she herself would have been still a child then, theechoes from Fukushima were simply too much for her.

Conversely the magnificent Maltese tenor Joseph Calleja had nosuch childhood memories. Malta is one of the majority of EU stateswhich have eschewed any nuclear construction. Calleja, a Verdi andPuccini specialist who has frequently wowed Covent Gardenaudiences, simply refused to travel to Japan whilst the radiationleaks continued.

Prima donnas throwing wobblies? Perhaps. After all, the showsdid go on, albeit with understudies, and with the permanent staffat the Met reminded firmly they had contractual obligations to bethere, regardless of any perceived dangers. But in my view, suchviolent reactions from two of the world’s greatest opera starsmade it plain. Attitudes to nuclear electricity generation havechanged after Fukushima. Not just in Germany, or in Switzerland.But all around the civilised world.

he UniGear 500R range of medium voltage (MV) primary

metal-clad air insulated switchgear has been developed

specifically by ABB to meet the needs of customers

requiring the simplicity, lower cost and smaller installation

footprint offered by a fixed circuit breaker panel. At just 500 mm

wide, the UniGear 500R represents a significant space saving

compared with standard switchgear panels, especially in typical

applications where banks of 10 or more panels are installed. The

panels can be rear wall mounted if required and are ideal for

containerized substations.

Maximum safety and reliabilityThe UniGear 500R panel ensures maximum safety and reliability,

with mechanical interlocks between the circuit-breaker, three-

position line disconnector and cable testing device. All

components can be accessed directly from the front, so there is

no need for rear access for maintenance and service operations.

The panel incorporates ABB’s well proven Vmax vacuum circuit

breaker in a special fixed version – if a problem should arise it

can be replaced in less than 90 minutes.

Based on a well proven designThe UniGear 500R has evolved from the well proven UniGear ZS1

range launched by ABB in 2004 to provide the world’s first ‘one

size fits all’ platform for primary MV air-insulated switchgear in

the 12 to 24 kV range. It is

manufactured at ABB’s focused

factory in Brno, Czech Republic

which is currently producing over

1,000 panels a month to meet the

regional demand for UniGear

equipment.

ENA approvedThe UniGear 500R has a

certificate confirming that it

meets the ENA Technical

Specification ENATS 41-36

covering distribution switchgear

up to 36kV for use by UK DNOs

(Distribution

Network Operators).

In its ENA version,

the UniGear 500R is

rated for voltages up

to 12kV and feeder

currents up to

1250A – approval for

the 2000A rated

model is expected

shortly. The UniGear

500R also complies

with the IEC 62271-

200 standard for

metal-enclosed

switchgear.

Flexible connectivityUniGear 500R panels offer a high level of flexibility to accommodate

both traditional and IEC 61850 based protection and control

solutions. In the IEC

61850 enabled format

the UniGear 500R

incorporates ABB

Relion® IEDs (intelligent

electronic devices),

such as the REF615

feeder protection relay,

that meet the highest

GOOSE (Generic Object

Oriented Substation

Event) performance

requirements for

tripping applications in

distribution substations.

A wide range of applicationsOver 250 UniGear 500R panels have already been installed in a

number of UK applications that require a compact, space-saving,

low-maintenance solution, such as data centres, wind farms,

industrial projects, hospitals and major sporting venues.

One-stop shop for MV distribution switchgearAn important advantage of the UniGear 500R is that it

coordinates perfectly with the complete UniGear ZS1 portfolio

enabling ABB to offer a complete ‘one-stop shop’ approach for

MV distribution switchgear. This makes it possible to specify on

the same busbar, a UniGear ZS1 with withdrawable incomer, a

UniGear 500R removable circuit breaker outgoing and a motor

control centre (MCC).

12 Electrical Review July 2011

WHETHER YOUR COMPANY is considered part of the UK’s

‘critical infrastructure’ or not, the consequences of a malicious

security breach could reach catastrophic proportions. When

investigating the potential repercussions of a successful attack

for a cement company we learned a miniscule change to the

batch – minor enough in fact for it still to pass two levels of

testing – could result in a concrete application that was

inherently unusable for its intended application. If this concrete

was intended for a large building foundation, for example, the

forces involved by the time you reached the fifth floor of

construction may be enough to bring the whole lot down. Such

an example is not uncommon – we all know how much of our

world depends on products or processes that are managed by

control systems of some kind. Pasteurisation is another good

example, and one which is highly pertinent to the UK’s large

food and beverage sector. The

temperature at which pasteurisation

occurs is precise and lowering the

temperature at which the control system

requires the process to operate at could

result in the whole process providing the

ideal environment for dangerous

bacteria to grow, rather than the

intended environment which kills

bacteria and helps make the product

safe for consumption. The threat to

utilities is also well publicised- a

malicious cyber-attack could destabilise

and possibly bring down power to a

city, choke off a water supply or cause problems at an oil

refinery or underground mine.

It is now a year since the world first heard the word Stuxnet.

During that year it has become the most talked about and

studied piece of malware ever. Stuxnet combined the two

principle methods of compromising and traversing a computer

system in such a way as to harness both methods for

maximum effect. The first of those methods is ‘pivoting,’ which

is the act of compromising a networked machine, then using

that machine’s authorised position on the network to attempt to

compromise other systems. Essentially the malicious threat actor

uses the compromised system as a pivot point from which they

can use the network access of that machine to retrieve data or

infect other systems. The second method is that of being semi-

autonomous: traditional viruses look for a single vulnerability in

every system they touch and once identified that malcode will

pass exploit code to compromise the vulnerability and deliver its

payload. Stuxnet effectively and elegantly blended these two

very distinct methods resulting in a semi-autonomous,

disconnected attack using traditional network penetration

techniques such as target analysis and pivoting to reach,

compromise and ultimately physically destroy its intended

target. Using these methods in conjunction with a well-

engineered attack framework, Stuxnetproved to be rightly

frightening – especially to those who work in utilities and

industrial environments. A Stuxnet style attack has raised the

bar from a malcode development standpoint through its

employment of that framework based, disconnected and semi-

autonomous method to seek out and compromise a very

distinct and specific target. That is why Stuxnet is and will be

studied for years to come.

However, despite the undoubted sophistication of the

malicious codebase, it followed the traditional threat model for

attacking systems – it used an easily attainable point of entry-

Windows software – and infected by networking from this entry

point until it found its target, where it set the control system

against itself to sabotage a particular process. The fact even

Stuxnet followed the traditional threat model means that

companies that properly audit the security threat to their

systems are far less vulnerable to similar attacks in the future.

There is much written about the vulnerability of industrial

systems to attack – unfortunately, the same fear, uncertainty

and doubt which makes a good headline is also used to sell

equipment and services. The unwelcome fear, uncertainty and

doubt elements are a disservice to industrial security as there

are many things that asset owners can action to improve

security against a Stuxnet type attack, and vastly reduce the

negative effects of any security breach without the need to

invest large sums in new products. Governance is a key aspect

of this – from keeping up to date with security patches from the

companies that designed your software and firmware, to

understanding the nature of risks to your specific application

from your own engineers and IT specialists and taking

appropriate action to reduce your vulnerability, asset owners

can improve and manage security more tightly.

Many of the vulnerabilities of industrial security systems,

whether ‘critical infrastructure’ or not, originate from a distinct

disconnect between engineering and IT elements of system

design and implementation. This comes from their inherently

different perspectives and applications of technology and also

in the culture of operatives. The goals of most IT designed

systems are for full network access at every possible point

(node) in order to create a seamless system. From the IT cultural

standpoint sharing of knowledge is less natural as it is

associated with a loss of power or value. The traditional

engineer, on the other hand, comes from the culture of

mentorship and sharing of knowledge associated with the

scientific approach which is concerned with variable reduction,

reassessment and repetition until the fewest possible points of

fault are achieved. In an industrial application these distinctions

are important.

Owners and operators of control systems should be aware of

their equipment to the extent that they can define which

devices need to speak to which other devices in order to

achieve the necessary connectivity to perform the functions

required. Once identified, this information can be used to

disallow any communications that are outside those identified

as necessary to perform the task, but within the capability of the

equipment. This is often referred to as the ‘Principle of Least

Privilege’, and also falls within the ‘Principle of Least Route’

which is similar but goes on to add a further layer of security by

including the ‘reachability’ and ‘Zone segmentation’ of the

equipment via small sub-networks and access control limits

(ACLs) (subnet = /29 or /28).

For example, if a manufacturer has five process lines with

two PLCs on each line that need to be able to communicate

with one another, but not the PLCs on other lines, it is

important that authorisation on the network limits the

connectivity of the PLCs in order to reduce the risk to the

system. Effectively, this approach is ‘engineering out’ risk at a

network level, by reducing the privileges of the machine to

those required to perform its function and no more; the

capability of the machine or its operator to cause a fault or be a

security risk is thus reduced.

Engineering out risks is one example of a range of tactics to

reduce vulnerability. Other ways to reduce risks is by including

security technologies such as anti-malware, host intrusion

detection and prevention systems, and strong firewall-type

products (i.e. Unified Threat Management (UTM) devices) in

industrial control systems.

There are four steps that I would advise every asset owner or

manager to take to helpreach the necessary security levels for

your company and the people who rely on your outputs:

� Understand what you have: Whether you work with

nuclear power or cheddar cheese, you must understand

your environment and the equipment, including

connectivity capability.

� Understand the devices that you have and how they need

to interact: This should happen from a process perspective

(your engineers can help with this) and a network

perspective (IT can help with this). Identify any gaps

between the two in your existing infrastructure. Typically

there is a gap caused by the builders of the information

system not knowing the process environment. This can be

thought of as two technology groups that don’t talk to one

another properly. Stuxnet and similar threats use one

against the other.

� Assess who has access and to what: This is about the

human environment- technical and non-technical controls

that can be used to strengthen the security. What levels of

physical security exist between staff and access to mission

critical systems? What access local control HMIs have to the

network?

� Instil a security culture: Approach security training from a

risk perspective. What are the risks of employees breaching

security protocols, or failing to maintain appropriate

software or equipment? Most people understand the risk

involved in double clicking an email attachment on their

home computer when it comes from an unknown or

unsolicited source and won’t do it. Understanding the risk

to the industrial control systems and networks of their

workplace and taking appropriate steps to avoid exposing

the company through carelessness, human error or breaks

with protocol is the responsibility of everyone in the

company.

Of course there are network security service providers that

can offer a complete service which will incorporate all of the

above steps and help you to identify, design, implement,

monitor and manage your security. Using a ‘vendor agnostic’

service is advisable, especially if you have equipment from

various vendors and wish to take a fully ‘joined up’

approach. The precise nature of service offered will vary, but

certain elements are vital and you should expect to be

involved in every aspect of the process from the outset as it

should be bespoke to your organisation’s needs. Here are

some key services to look out for in an external network

security service offering:

Assessment:

� Existing policy assessment.

� Existing design assessment

� Onsite assessment (including operational, risk and

vulnerability assessments)

Development/design:

� Security policy development

� Security design development

� Business continuity planning

� Disaster recovery planning and incident response planning

Implementation:

� Security configuration implementation

� Non production penetration testing

� Security policy training

Auditing:

� There are accepted security standards and government

standards that may apply to your company which you can

be evaluated against, for example NERC CIP standards, IEC

62443, ISA-99, NIST 800-53, NIST 800-82, etc.

Ongoing management:

� Remote monitoring

� Incident response services

� Disaster recovery services

It seems simplistic to point out the nature of the risk

to staff, business, consumer and community is specific to

the business in question and the nature of the security

incident, yet it remains one of the key principles for

creating the most robust security environment. The

security processes, protocols and management for your

business should be unique to the risks inherent in your

system and the requirements of the equipment in place.

A year on from the first Stuxnet news stories the fact this

new and powerful malware entered systems according

to a traditional threat model often goes unmentioned

but highlights the need to approach security with

renewed vigour. By using tried and tested techniques

alongside continuous governance and applying a holistic

view of the industrial facility or utility in question to

close known or predictable vulnerabilities, asset

owners/managers can drastically improve their defences

and help protect their business and those who rely on its

safe management.

16 Electrical Review July 2011

WITH ONLY A VERY few exceptions, currently, UPS systems

are based on one of three topologies: passive standby,

which is sometimes called off-line; line interactive; and

double conversion which is also referred to as on-line. The

essential elements of each of these are shown in the

accompanying diagram and we will shortly examine them

in a little more detail. Before doing so, however, it is useful

to look at the functions a UPS may be required to perform.

The most obvious

function of a UPS system

is to maintain power to

connected equipment

when power from the

mains is interrupted.

However, there are no

fewer than eight other

power problems that a

UPS may be called upon

to perform.

These are

compensating for short-

term low voltage

conditions (power sag);

eliminating supply

transients (power surges);

compensating for medium-term low voltage conditions

(brownouts); dealing with medium-term overvoltage on the

mains supply; eliminating electrical noise on the mains

supply; compensating for supply frequency variations;

eliminating switching transients (notches) and dealing with

harmonic distortion of the supply.

Not all of these functions are required in every

application, of course, and choosing a UPS that offers only

those functions that are actually needed, instead of

notionally playing safe by specifying a UPS that does

everything, can be the key to making very useful savings.

With this in mind, let’s take a close look at the three UPS

topologies.

In a passive standby UPS, when mains power is available,

it is filtered to minimise power surges and supplied directly

to the load, without any form of active conversion. At the

same time, the battery is charged. If the mains power is

interrupted, the UPS delivers stable power to the load from

the battery, via the inverter. UPS systems of this type are

inexpensive and can be a good choice for protecting, for

example, individual PCs in SOHO (Small Office Home Office)

and non-critical applications. They are not, however,

generally considered suitable for more demanding

applications.

This is partly because they provide only three of the nine

possible protection functions (power failure, power sag and

power surge) and partly because under brownout

conditions they will use battery power, which will be

exhausted after the planned back-up period. By contrast,

other topologies will compensate for the low mains voltage

without calling on power from the batteries and can

therefore continue to operate indefinitely during a

brownout.

For these reasons, the choice of UPS topology for critical

applications such as data centres and other medium to

large scale IT installations is invariably between line

interactive and double conversion. At first sight, the line

interactive topology looks very similar to the passive

standby technology. The key difference, however, is the

inclusion of circuitry that can either increase or reduce the

supply voltage before delivering it to the load, without

needing to call on battery power.

In modern line interactive UPS systems, the incoming

mains voltage is continuously monitored by a

microprocessor-based system and, if this voltage moves

outside of a pre-determined range, compensation is applied

instantly and automatically. This type of UPS can, therefore,

provide not only the three protection functions available

from passive standby systems, but also protection against

undervoltage and overvoltage conditions.

Line interactive UPS systems are typically priced

somewhere between passive standby systems and double-

conversion systems, and are certainly worth considering for

most applications, provided the frequency of the mains

supply will be reasonably stable, and that the supply is not

unduly contaminated with transients.

UPS systems based on double-conversion topology are

usually seen as the top-of-the-range option and, in many

respects, this is true. They comprise of a rectifier that takes

power from the mains and converts it to DC. This is used to

charge the batteries and to supply the output inverter,

which converts the DC back to clean AC to supply the critical

equipment. If the mains fail, the battery takes over the duty

IELLO UPS is proud to protect Sudlows’ award-winning

data centre with its Multi Sentry Uninterruptible Power

Supply system.

Last month the North West based data centre specialist scooped

the prestigious Data Centre Solutions’ Innovative Data Centre Project

of the Year Award 2011 in recognition of Sudlows’ unique Data

Centre Innovation Pod (DCiP) - one of the most pioneering micro data

centre facilities in the UK.

Sudlows has designed and built a fully functional data centre to

demonstrate its expertise to both current and potential clients. The

1,000 sq ft facility, costing almost £500,000, was completed back in

2010, and with it, Sudlows has claimed a place as a centre of

excellence in the field of data centre design and solutions.

But integral to any successful data centre is the highest quality power

protection, and this is where Riello UPS, one of Sudlows’ key suppliers,

enters the picture.

Sudlows is renowned for advising its clients on the latest in energy

and money saving technologies, so with this in mind the company

approached Riello UPS to contribute to the project.

Robin Koffler, general manager of Riello UPS (UK), said: “Riello

UPS worked closely with Sudlows to organise the many aspects of

the UPS installation, commissioning and testing; selecting the100kVA

Multi Sentry UPS to illustrate to Sudlows’ clients the typical footprint

of a UPS.

“The system provides eight minutes of protection when at full load.

With Sudlows’ usual power requirements using only 20%, the Multi Plus

would protect the business for 40 minutes.

“With a continuous supply of conditioned, reliable power ensured by

the Riello UPS Multi Sentry, this fully working showroom allows

Sudlows’ clients to experience state-of-the-art product application and

innovation in a functioning data room packed full of the latest

technology.”

He added: “Riello UPS is pleased to be able to offer an extensive line

of environmentally-friendly, energy efficient products that not only meet

the most challenging demands of the data centre environment, but also

meet the scalability requirements of this growing business sector.”

Andy Hirst, projects director for Sudlows, said: “The UPS in a data

centre is a critical requirement and one of, if not the most important

pieces of kit.

“Riello UPS is one of our key preferred suppliers and we have total

confidence in their products and services.

“We’ve always had total support from them throughout all our

projects and this is very refreshing. When it comes to UPS products and

services, Riello UPS is unbeatable.

“We work with many contractors and suppliers and we are renowned

for our quality projects and services. We have to ensure that we work

with the best as our reputation in on the line.

“This is why you will see Riello UPS units in the majority of our projects.”

of feeding power to the inverter without any gap in the

voltage during changeover.

Double-conversion topology very effectively isolates the

load from anything untoward that may be going on with

the mains power, and a double-conversion UPS can,

therefore, provide all nine of the possible protection

functions discussed earlier. In the most critical of

applications, therefore, double-conversion is a natural

choice, but that is not to say that it has no drawbacks. It is,

for example, the most expensive of the three topologies and

because power is converted twice on its way to the load, it

is inherently less efficient than the other two topologies

when operating with the mains supply present.

It is worth noting, however, UPS suppliers are now

addressing this efficiency issue. Part of the solution, of

course, is to improve the efficiency of the converter and

inverter, but there is a limit to the gains that can be made in

this way. This has led to the development of more

innovative solutions, such as a system that effectively

bypasses the UPS and feeds power direct from the mains to

the load when the mains is healthy, but instantly reverts to

full double-conversion mode should any problem occur.

The best systems of this type achieve efficiencies of

around 99% when in bypass mode, and switch to double-

conversion mode in less than two milliseconds, thereby

ensuring there is no disturbance to even the most sensitive

of loads.

As we’ve seen choosing the right topology is an essential

first step in specifying a UPS installation. Making that choice

is, however, not always as straightforward as it may at first

appear. For this reason, there is much to be said for seeking

advice from an experience UPS supplier that can offer all

three technologies and that will not, therefore, be swayed

by commercial bias but will offer dependable guidance

based on the requirements of the application alone.

any users of

UPS solutions

are under the

illusion that in order to

achieve high efficiency

levels, in excess of 90%,

compromises need to be

made in terms of

protection by removing

the output isolation. However in doing this, electrical isolation can be

lost, loads are exposed and in the event of a major failure, DC will

reach the load and can cause extensive damage.

Transformerless units may have had the edge a few years ago, but

the development of new technologies means that companies like

Borri, a supplier of UPS equipment in the UK, have been able to

develop sophisticated transformer-based units which can achieve

the same high efficiency levels of standard transformerless systems.

The company’s range of ECO UPS systems provide maximum

efficiency without compromising on performance and all come with

output transformers as standard, which makes them flexible across a

wider range of applications. Delivering the highest levels of

protection, Borri’s transformer range of UPS solutions achieves high

efficiency even in permanent online dual conversion mode.

A typical transformer-based UPS operates at around 88%

efficiency at full load, while Borri claims its ECO UPS transformer

solutions are 95% efficient. Though seven percent may not sound

much, over a five year period the difference on a 100kVA UPS could

mean savings of a massive £18,000 in energy consumption costs.

Given that energy prices are only set to rise over the coming years,

this type of saving will be hugely significant to any business.

Borri’s ECO range of three phase UPS equipment is the only

transformer-based type to have made it onto the government’s

Energy Technology List (ETL). The ETL is part of the Enhanced

programme to fight climate change by providing tax incentives for

businesses investing in equipment that meets energy-saving criteria.

IN GENERAL, power networks are designed with a

relatively low impedance between the generators that

provide the source of electrical power and the users of the

power – the system loads. The aim is to maintain a fixed,

stable system voltage while the current varies to meet the

changing loads. The main advantage of this approach is

that the individual loads are effectively independent of

each other, so that network stability can be maintained as

they change. It does though have an important downside,

which is that substantial fault currents – typically between

five and 20 times the nominal current – can develop

during network disturbances.

Over time, the maximum fault current in a network

has tended to increase for a number of reasons:

� Increasing demands for power and the resulting

need for increased generation are pushing medium

voltage (MV) power grids to their maximum operat-

ing limits

� Parallel distribution paths are being added to net-

works to support load growth and there are a

greater number of interconnections within the grid

� The development of distributed generation, such as

wind power and CHP schemes, are adding complex-

ity to an already complex system

The net effect is short circuits can occur more often

and are more likely to cause high, uncontrolled fault

currents, leading to damage of electrical networks and

consequent power failures.

Until now, operators of public and industrial electrical

networks could only have limited protection against high

short circuit currents, either by the use of complicated

equipment or by over-rating of components. There are

concerns as potential fault current levels continue to

increase they will soon exceed the protection capabilities

of existing equipment.

There are two possible solutions to this challenge.

Utilities could upgrade their substations to handle the

new maximum short circuit currents – which would

require multi-million pound investments in new

infrastructure. Or they could add a device that reduces

the potential short circuit currents to a level that their

existing substations can handle – a fault current limiter.

The Superconducting Fault Current LimiterLeading manufacturers and research establishments

have been investigating fault current limiting devices

for several years in order to offer an alternative to

network reconfiguration/asset replacement in tackling

rising fault levels. The Superconducting Fault Current

Limiter (SCFCL) is designed to be a low risk fail-safe

device, utilising a non-linear ‘high-temperature’

superconducting (HTS) ceramic rather than electronic,

electromechanical, mechanical or pyrotechnic

components.

When the superconducting element is cooled below

its critical temperature it loses all electrical resistance,

thereby allowing normal load current to flow with

negligible losses. The operating temperature of -196°C,

which is well below this critical temperature, can be

obtained using relatively inexpensive and readily

available liquid nitrogen. Any rise in temperature – due

either to the increased current density caused by the

passage of a fault current, or the loss of the cooling

medium – will cause the superconducting material to

revert to a normal resistive state.

This added resistance has the effect of reducing the

fault current to a lower, more acceptable level. This

process is referred to as ’clamping’ because it effectively

sets a limit above which the fault current will not rise.

The SCFCL operates in a few milliseconds, after which

its resistance remains high until the fault current is

cleared by a circuit breaker. The SCFCL’s fast operation

ensures that the first peak of the fault current is limited;

this is vitally important when considering the closing of a

circuit breaker onto a section of faulty network. The

degree to which the subsequent current is limited can be

set at the design stage to suit a specific application. In

many cases this level could be selected so that existing

protection arrangements do not need to be adjusted.

SCFCL advantagesNexans has developed commercially available SCFCL

devices that are capable of clamping fault levels to

within network design limits. They offer a number of

benefits:

• SCFCLs could be strategically deployed onto the

network in areas either with existing high fault level

issues, or where there is a high degree of distributed

generation connection activity (e.g. urban CHP schemes

or wind farms). In this application SCFCLs could provide

a method of deferring the replacement of switchboards

or reconfiguration of networks while ensuring fault

levels are maintained within safe limits.

� Where fault levels are generally high, there may be

operational benefits associated with minimising the

often complicated switching required to ensure that

equipment operates within its fault rating during

network reconfiguration and outages. This could re-

duce the risk of incurring customer interruptions

arising from either network switching or from oper-

ating parts of the network temporarily on single cir-

cuit security. An improvement in personnel safety

may also be possible.

� If the size of network fault currents are restricted,

equipment will be subjected to reduced electrody-

namic and thermal stress (these are both proportional

to the square of the current, so a modest reduction in

fault level results in a considerable reduction in these

stresses), potentially reducing the probability of con-

sequent faults and prolonging the asset life.

� SCFCLs may, subject to resolution of protection is-

sues, allow existing radial circuits to be operated on

an interconnected basis, with associated improve-

ments in the continuity of supplies to customers and

power quality (flicker and harmonics). This could fa-

cilitate a radical change in the way networks are de-

signed and operated.

Deployment of first SCFCLThe first field test of a Nexans SCFCL was carried out at

an ENW (Electricity North West) substation in Bamber

Bridge, Lancashire where it was live on the grid from

October 2009 to June 2010. This site was selected as

representative of a location where an SCFCL might be

installed in response to a real need.

The two 33/11kV transformers feeding the substation

had been recently upgraded, with the result that the

fault level increased to above the making and breaking

capacities of the existing circuit breakers. It was

therefore necessary to build a new substation and

install a new 11kV switchboard of primary distribution

circuit breakers comprising 10 feeders, two incomers

and one bus-section. So, while the fault level problem

was addressed in a conventional manner, the situation

allowed the design of the SCFCL to be determined

according to realistic criteria, providing a solution to the

fault level issue.

World’s first SCFCL installation in a power plantAt the end of 2009, Nexans commissioned the world’s first

SCFCL to be installed in a power plant. In this pilot project

for Vattenfall Europe Generation AG, the SCFCL was used

to provide short-circuit protection for the internal MV

power supply that feeds coal mills and crushers in the

Boxberg brown coal power plant in Saxony, Germany.

The 12 month project enabled Vattenfall’s experts to

gain valuable hands on experience with innovative

SCFCL technology that they believe will offer significant

benefits in personnel and plant safety. Not only was this

the first time that this type of device had ever been used

in a power plant, which is a highly challenging

environment from a technological point of view, the

project was also implemented without public grants,

which is unprecedented on the world stage.

Vattenfall’s SCFCL, designed for a rated current of

800 A, received live testing by daily routine operation

in a feeder circuit of the 12 kV power supply for

rebound hammer mills (used for crushing coal). It was

designed and built by Nexans according to

specifications from Vattenfall and the Brandenburg

Technical University in Cottbus (Germany), which

n an industry where speed and quality count, the choice of

design software is critical. Amtech’s electrical design solutions

are available in a range of levels so that users can select the

functionality that best suits their needs. All products in the range will

accommodate the changes being introduced in Amendment 1 to the

17th Edition Wiring Regulations (BS 7671).

The complete range includes ProDesign for fast, accurate electrical

system design and calculation, SingleCable for quick single cable

calculations and Protect LV or HV for protection studies and device

selection. Designer Suite packages also incorporate PowerNet HV for

the calculation of short circuit currents in low and high voltage

distribution systems.

ProDesignProDesign electrical design software, available for projects with up to

400 distribution boards, is easy and quick to use with the ability to

‘sketch out’ single line diagrams in just a few minutes. Time saving

features include a massive database of manufacturers’ devices, as

well as the ability to create templates. ProDesign also includes error

reporting routines and a built in ‘help’ system. Plus you can easily

produce ‘what if’ scenarios within just a few clicks.

Protect LV and HVProtect LV and HV use the design information from ProDesign to

carry out protection studies without the need for specialist protection

expertise.

Protect LV is suitable for low voltage installations, Protect HV is the

ideal choice when working with both low voltage and high voltage

installations. Both include rich databases containing thousands of

protective devices, making it easy to select the most appropriate

devices.

SingleCableWith SingleCable you can size an individual circuit quickly and easily,

in accordance with BS 7671 17th Edition IEE Wiring Regulations. The

software is extremely simple to use and provides results in seconds.

Once calculated, the program also enables you to look at the results

for the next cable size and/or protective device - larger or smaller.

Advanced IntegrationAmtech software packages are designed to save time by sharing

information and minimising duplication of tasks. For example,

information from ProDesign can be exported to Protect LV or HV to

check co-ordination. The information is only entered once, and you can

switch between design and co-ordination with any changes made in one

package being automatically reflected in the other.

Information from ProDesign can also be passed to FastTest

certification software to save time on generating inspection and test

certificates. In addition, data can be exported to Excel or HTML formats,

reports can be generated in Word or PDF format and schematics can be

converted to DXF format.

Support you can rely onAll Amtech software is developed and supported under BS EN ISO 9001

TickIT and backed by the highest levels of service, with technical

support from fully qualified electrical engineers.

Amtech is also committed to helping its customers understand and

comply with the latest legislation. To that end, the company is currently

running a series of seminars on the 17th Edition, Amendment 1.

Don’t just take our word for it“There are a number of features I like about Amtech software,” says

Michael Brett of Brett Electrical Services. “As well as saving time and

making us more productive, its software makes it very easy to produce

professional looking reports for our customers, which gives them

confidence in us and enhances our image. The software has kept pace

with changes and the latest versions of the software show a real

understanding of our needs and, more importantly, the needs of our

customers. I have looked at other packages but Amtech outstrips its

competitors by far, and the technical support is superb,” he adds.

OVERVOLTAGES, electrical power surges or spikes are fast,

short duration electrical transients in an electrical circuit. It is

generally thought that up to 80% are generated from

internal sources such as inductive load switching and

normal equipment operations, while around 20% derive

from lightning strike and power utility switching. The result

can be cumulative equipment damage and possible

premature failure, expensive system resets, downtime and

data losses. Lightning strikes can cause catastrophic

equipment failure, resulting in longer-term business

disruption, plus expensive equipment repair and

replacement costs.

Surge protection devices (SPDs) regulate the voltage

supplied to electric and electronic equipment by shorting it

at extremely high speed to earth when they detect

voltages over and above a safe threshold, or by blocking.

They do this very effectively, yet their role seems to be

underplayed. Indeed it is only now surge protection is

likely to be included in amendments to the 17th Edition

Wiring Regulations.

The need for such protection should be self-evident as

industry and commerce relies ever more on devices that are

highly sensitive to voltage surges and spikes, while the

residential market has hardly any surge protection at all,

although the average number of domestic electronic

gadgets per household has increased.

The rapid and continuing growth of solar photovoltaics

(solar PV) and wind turbines means further applications for

SPDs, especially as solar PV arrays, with their metal roof-

mounted frames, are excellent lightning conductors, as are

wind turbines. Both are easily damaged by lightning strikes,

so surge protection should be high on the agenda.

Coordinating SPDsCoordinating the types of SPDs used is crucial. Typically this

involves the following device classifications:

Type 1 - Installed in the main electrical switchboard when

the building is equipped with a lightning protection system,

these can discharge a very high lightning current that might

be fed into the power distribution system.

Type 2 – Fitted in the main distribution switchboard, these

discharge indirect lightning strike current, which can cause

induced or conducted over voltages on the power

distribution network.

Type 3 - These are installed as a supplement to Type 2

devices to reduce sensitive equipment terminal

overvoltages. Their current discharge capacity is

very limited, so they should not be used alone.

For many applicationsCooper Bussmann’s new range of Surge

Protection Made Simple Types 1 and 2 SPDs offer

system installers and users a choice for solar PV,

wind turbine, IEC, UL and telecommunications

installations.

Modular pre-wired multi-pole DIN rail SPDs for

solar PV systems feature a fault-resistant Y circuit

comprising three protective varistor circuits and a

combined disconnection and innovative short

circuit interruption (SCI) mechanism. An integrated

DC fuse allows safe module replacement.

Complete surge protection is provided for all solar

PV systems in accordance with IEC 60364-7-712

and, uniquely, with UL 1449 (3rd Edition).

Multi-megawatt utility wind turbines are becoming

increasingly large, yet very big overvoltages and up to

400,000A peak currents can damage virtually all parts. The

loss of a single day through downtime for a 1.5MW machine

is estimated to cost around £55,000 (source: NREL), so

lightning strike protection is essential. Wind turbine SPDs

include lightning arrestors to 690VAC and both AC / DC

protection.

Telecommunications equipment is very susceptible to

damage from voltage spikes and surges, which can easily

harm sensitive electronics devices and network equipment.

Lightning strikes especially can cause catastrophic failure

because telecommunication conductors are copper based.

Telecommunications SPDs help assure equipment reliability

and assist in providing a clean power supply free from

damaging transients.

The SPDs designed for all IEC applications help protect

the user’s IEC system investment, and these IEC Class 1 and

Class 2 SPDs cover all major global markets. Finally, there is

the UL SPD range, which helps protect industrial and

commercial UL systems from damage. Vibration and shock

resistant is according to UL 1449 Third Edition. These are

identical devices to the IEC line but tested and rated to

appropriate power supply voltage requirements.

Easy choice and status indicationThe SPDs in Cooper Bussmann’s Surge Protection Made

Simple range, all have shock and vibration resistance to EN

60068-2 with IP20 finger protection. The range shares DIN-

rail design, colour-coding and a rejection feature

commonality that makes choosing, installing and

maintaining them very simple. Safety and simplicity are

crucial – just specify the system voltage and circuit

configuration and decide whether remote contact signalling

(which enhances status monitoring) is needed or not.

The heavy-duty zinc oxide varistor and spark gap

technology allows a high surge discharge, while colour

coding makes it harder to choose the wrong device. Special

rejection features obviate incorrect rating selection. Each

module can be removed by pressing the plug release

button, yet neither shock, nor vibration, nor the enormous

forces of the discharge affect safe connection to the base.

Note, every time an SPD operates its useful life degrades,

so it is important to have some kind of device status

monitoring. The easyID visual indicator shows green if the

device is fully operational; red if it needs replacing.

These SPDs effectively bring a one-stop-shop for

specifiers and installers looking for proven solutions.

CORRECT MANAGEMENT of cables is something that needs

careful consideration when undertaking a panel building

project. Clear identification of each cable and component

is will ensure the best option both for short and long term

use. There are many products and techniques available

today that offer a number of solutions for panel builders

and those involved in their use.

One of the latest product solutions on the market is to

use stainless steel marking systems which in addition to

panel building applications, can also identify wiring and

cables in more general electrical situations, as well as

pumps, pipes and valves.

Selecting a stainless steel system offers many benefits,

but the prime advantage is the marker itself is highly

durable and because the lettering is embossed into the

steel, there is no chance the code, wording or message

will rub off or fade over time. If the application is for a

particularly aggressive environment, such as the rail

industry or oil and gas sector, this can prove to be an

invaluable benefit.

An example of such a system is the M-BOSS Lite from

HellermannTyton, particularly when used with the

company’s durable stainless steel MBT ties. The

embossing process is carried out via a special marking

machine which can be situated in the workshop or

manufacturing facility and due to its light and portable

design, can easily be transported out onto site. Quiet

operation also ensures there will be little or no disruption

if use in an office environment was necessary. The

computer driven machine is able to emboss characters

directly onto the stainless steel markers, which are then

secured to the component that needs identifying.

Such products are the result of ongoing research and

development involving customers as part of the process

to ascertain their wants and requirements. In addition to

being compact and easy to transport, fast printing

speeds, easy to use software that can carry out small or

medium printing volumes to 10mm or 20mm marker

plates were some of the ‘wish list’ items in the case of

the M-BOSS Lite.

Finished marker plates can then be tied in place with

the MBT ties and it is normally recommend that a proper

cutting tool, such as the Mk9 SST, is used to correctly

tension and cut the ties, leaving no sharp edges.

For more general panel building use, key to any

project where identification is required is to ensure the

right type of product is selected for the correct job. As

well as stainless steel, markers are available in a wide

range of materials, depending on how and where they

are going to be used. For example, zero halogen (HF) and

limited fire hazard (LFH) are rigorously tested for toxic

smoke generation, flammability and flame propagation

to ensure that in the event of a fire, fumes from burning

electrical installations are not a danger to the public. A

typical example of this for use in enclosed environments,

such as underground railway stations.

Another possible solution for panel building

applications is the use of HellermannTyton’s TT420+

printer for heatshrink sleeving, particularly when theCaption

marking of different cable sizes is required and a range

of printable sleevings can be used. Where budgets are a

major consideration, these can work very well by

eliminating the need for legends to be made up using

individual cable markers. As the tubing fits around the

cables, the marking then becomes permanent as a result

of the heat process. It is virtually impossible to remove

heatshrink tubing or to tamper with it once in place and

as it has a good resistance against solvents and

aggressive chemicals, it ensures the cable identification

remains intact.

In addition, heatshrink tubing also works well in

extreme temperatures and there are products available

that continue to function in temperatures of as low as -

55 deg C and as high as +135 deg C, therefore providing

a solution for the toughest of environments.

Increasingly these days, saving installation time is

becoming more and more important, which is why

printing identification markers on site can be a major

advantage. The use of thermal transfer desk and bench

top printers can offer the answer which enables all

markers to be produced as and when required, avoiding

trips back and forth to obtain the required labels. Having

the use of an onsite printer also enables last minute

work to be completed, or changes can be accommodated

at short notice. This will help to reduce waste and any

downtime and will also save money.

Furthermore when using such systems, other types of

labels can be produced, for example terminal block

identification, labels that replace engraved plates and

self-laminating labels for wires that are already

connected. In fact, most of the identification

requirements for a panel builder could be covered with

one small investment.

Where this level of financial investment is not a viable

option, more familiar, tried and tested slide on core

makers can still be used. These markers have individual

letters and numbers and are then threaded onto wires

and cables to produce the required text and/or numerical

legend. Alternatively, if risk and safety are not crucial

considerations, then a simple, coloured cable tie can also

be used to provide a cost effective solution.

Getting the cable management and identification side

of things right when building panels and systems is an

important consideration. Involving equipment

manufacturers in the process at the outset can offer

significant benefits to ensure a smooth running and

effective solution.

OUR GRUMPY OLD MAN WEARS A SERIOUS HAT THIS MONTHFOLLOWING THE DISASTER AT THE FUKUSHIMA DAI-ICHI

ATOMIC POWER PLANT. HE PLEADS WE SHOULDNOT WAIT FOR A DISASTER TO PROMPT UKNUCLEAR COLLABORATION

I have always found it intriguing how hard timestend to drive people apart, yet disasters bringthem closer together. From adversity good cansometimes come.Such has been the case following the

Japanese nuclear catastrophe where formeradversaries China and South Korea quicklyjoined with Japan in pledging both nuclearsafety collaboration and strengthened tradeagreements.Immediately after the terrible events following

the recent Japanese earthquakes and Tsunami, Iwas tempted to write about how I feared theoutcome would set the global nuclear powerindustry back a further decade or more. I amglad I didn’t. Human tragedy really does

surmount other issues.That

being said, the concerns expressed to Japan’sPrime Minister Naoto Kan by China’s ChinesePremier Wen Jiabao and South Korean PresidentLee Myung Bak, extend to far more thanhumanitarian issues. The three leaders haveagreed upon transparency over the crisis at theFukushima Dai-Ichi atomic power plant andindeed, they visited the site together.This in turn is leading to improved trade

pledges. “Rebuilding Japan’s disaster-strickenarea and economic recovery is not just about thewelfare of the Japanese people,”Wen said. “It isalso about economic and trade relations betweenour three countries, as well as about globaleconomic growth. We’ll make maximum effortswith all good will to support Japan’s recovery.”China, Japan and South Korea will seek to

begin negotiations on a free-trade agreementnext year and conclude talks on an investmentaccord this year. The three countries also agreedto accelerate a joint study on a trade pact by

the end of this year, a year ahead ofschedule. This is all good stuff in thewake of a massive and unusualnatural phenomenon that carriedsuch hideous consequences.

However, I must now return tomy fears about the metaphoricalfall out following the Dai-Ichicase. The situation in Japan isexceptional. The power stationsaffected are of an old design.Newer systems have much bettertechnologies to shut down and

cool stations hit by earthquakes.

And, in the case of Britain’s policy choices, wedon’t have to worry about earthquakes becausethe very few that happen here would neverthreaten a nuclear facility.However, European neighbours knee jerked.

Germany temporarily closed its oldest nuclearinstallations and suspended plans to extend thelife of others; Switzerland put a hold on thebuilding of new stations. Here, we have at leastbeen a little more circumspect where the chiefnuclear inspector, Dr Mike Weightman, is holdingan inquiry into the implications for Britain ofFukushima.I have said it many times before in this column.

If we are serious about fighting global-warming,there is no alternative to building new nuclearcapacity. Renewables, such as wind power, havetheir place but cannot possibly fill the gap in time.So nuclear it is. At the moment nuclear generationaccounts for about 18% of our electricity supply,compared with 76% in France.So, should Britain proceed with building

eleven new nuclear power stations on existingstation sites? Within 10 years Britain will havelost about a quarter of its existing electricitygeneration capacity, both nuclear and coal-fired.This is in spite of an increasing demand forpower. Irrespective of what happened at Dai-Ichithis short fall has to be made good if the lightsare not to go out.Of course, we could follow the Far Eastern

model and properly, transparently and fullycollaborate with our neighbours, but let’s hope itdoesn’t take a disaster to make us see that is away forward.

FALL OUT CAN BE FOR THE GOOD
