ATKINS AND FUSION FOR ENERGYSIGN ITER ENGINEERING CONTRACTAtkins, as part of the Engage

consortium, has signed one of the

biggest engineering contracts in

Europe with Fusion for Energy (F4E).

The consortium has been awarded

the architect engineer contract for

the building and civil infrastructures

for ITER, the world’s latest

experimental nuclear fusion reactor

in southern France. The Engage

contract is valued at approximately

€150m.

Martin Grant, managing director of

Atkins’ energy business, said: “ITER

ranks as one of the most technically

challenging projects the world has

ever seen and it must be delivered

to a time-critical schedule. This is a

remarkable opportunity for Atkins to

showcase its engineering and

management skills on the world

stage and, together with our partners

we are now at the centre of a

scheme that will pull engineers

together across country, company

and skills boundaries”.

“As members of the Engage

consortium we will be involved in

all stages of the design and

construction of the ITER complex,

providing civil, structural and

mechanical engineering, together

with commercial management

through our cost consultants,

Faithful+Gould. Atkins has been

involved in the nuclear sector for

nearly half a century, and with over

1500 people with nuclear skills we

are one of the most experienced

and well-resourced consultancies in

the UK.

The Engage consortium is made

up of Atkins, Assystem (France), Iosis

(France) and Empresarios Agrupados

(Spain). As architect engineer, the

consortium will assist F4E during the

entire construction process, from

detailed design to works completion

for the ITER buildings as well as the

site infrastructures and the

distribution of the power supplies. At

the peak of the design activity, more

than 230 engineers and designers

will work on the contract.

A Swedish energy company has

increased the amount of energy

it can sell by 35 GWh/year with

the installation of ABB medium

voltage drives.

Mälarenergi had been using

resistors connected to slip-ring

motors to control the speed and

hence the flow in the district

heating pumps. The heat from

the resistors was used in the

production of district heat. This

method of using the heat

created by the losses is

comparable to using electricity

to produce district heating, an

expensive method with today’s

high electricity costs.

The company invited ABB to

perform an energy appraisal,

which revealed a lot of energy

could be saved by upgrading

the pump and fan applications

with variable speed control

technology. ABB replaced the

resistors and slip-ring motors on

the district heating pumps with

variable speed drive systems,

including drives, high efficiency

motors and transformers.

TAS Engineering Consultants, a Stockton-on-Tees

headquartered electrical, instrumentation, automation

and control engineering specialist, has been acquired

by GSE Systems.

GSE Systems, based in Baltimore, Maryland, USA

and Glasgow, UK, is a leading global provider of real-

time simulation and training solutions to the power,

process, manufacturing and government sectors.

The acquisition will provide GSE Systems with a

stronger UK and European presence by enabling TAS

to deliver simulator-based training and engineering

solutions.

The deal is said to have the potential to enable TAS

to double the size of its workforce over the next

three-to five years.

Central to the growth will be TAS’s ability to design

and construct control room simulators for the energy

industry, which allow power plant operators to

simulate the exact operations of a plant in a training

scenario. The company will also provide training

services for the simulators.

On the back of this growth, TAS has almost

doubled its turnover to £2.4m in the last two years

and anticipates continued growth following the

acquisition.

John Maplesden, managing director of TAS, said:

“As part of GSE Systems we will be able to build

upon the growth we have already achieved. We have

enjoyed excellent progression in the past few years

and, with the security and resources associated with

a major international company, we can implement a

programme of investment and recruitment that will

take the business forward.

“Entering the simulation facilities and training

sector is a natural progression for TAS and enables

the company to establish an increased presence in a

rapidly expanding power generation sector.”

He added: “This acquisition also proves the depth

and breadth of engineering expertise, which exists on

Teesside. GSE Systems have recognised the high

standard of the industry in the area and the quality of

the workforce, particularly those who have helped to

build TAS.”

Graham Wren, GSE Systems managing director in

the UK, said: “The acquisition of TAS brings strong

and complementary skills and experience into the

GSE family of companies. The combination of world

class simulation technology from GSE and strong

project management, electrical and control

engineering will allow us to provide our customers

with an enhanced service from design concept

through plant commissioning to operational support

and training.”

WEEE and lamp recycler Electrical Waste Recycling

Group (EWRG) and electrical wholesaler City

Electrical Factors (CEF), both owned by the Mackie

family, have brought court proceedings against

compliance scheme Recolight and four major

lamp manufacturers.

The dispute centres on Recolight’s alleged

refusal to accept or be responsible for any lamps

collected by CEF and EWRG.

Philips Electronics UK, GE Lighting, Osram and

Havells Sylvania UK together have an 80% share

in the lamp market, and are also majority

shareholders in Recolight. CEF and EWRG allege

Recolight is controlled by these manufacturers,

though it is said both companies acknowledge

Recolight is an open scheme.

Since 2007, manufacturers have charged

electrical wholesalers like CEF 15p per lamp to

cover the cost of treating and recycling waste

lamps. This surcharge goes to Recolight, who in

turn is responsible for recycling these old lamps

when they are returned, though CEF continues to

pay the 15p per lamp surcharge to

manufacturers.

CEF alleges Recolight has refused to accept

bulbs collected from its customers since 2008,

and CEF (under its obligation to take old lamps

away once it has replaced them with new ones)

has been forced to arrange and pay for the

collection, treatment, recovery and disposal of

these lamps.

EWRG was one of a number of recyclers

contracted by Recolight to recycle lamps. It

alleges Recolight has refused to accept

responsibility for any lamps collected by and

processed by EWRG under the firm’s existing

business arrangements with a number of

commercial organisations, including CEF and

other national electrical wholesalers. EWRG is

therefore burdening the cost to recycle the light

bulbs despite the fact that the manufacturers are

charging substantial sums of money to meet

these costs via Recolight.

CEF and EWRG are claiming at least £350,000,

but it is thought the figure may run in to millions

of pounds. The writ itself claims the levy

generates £3.8m a year for Recolight.

A statement from Recolight said: “Recolight

strongly denies the claims by Electrical Waste

Recycling Group and City Electrical Factors, and

has filed a robust defence in the High Court, fully

setting out its position.”

EWRG and CEF said in a statement: “It is

alleged by us the actions of the manufacturers

and Recolight are anti-competitive and a breach

of both domestic and European law. Their actions,

we allege, have caused financial damage to both

claimant companies and in particular to EWRG

which has been compelled to undergo a recent

restructuring and redundancy programme to

allow it to continue to meet its contractual

obligations to numerous third parties, something

which it is determined to do.”

Reports suggest Recolight decided not to

renew some contracts with EWRG because of

health and safety, environmental and quality

concerns at two of its plants. In February of this

year, EWRG was fined £145,000 for exposing

workers to toxic mercury fumes at its

Huddersfield recycling plant, after pleading guilty

to breaching Section 2(1) of the Health and Safety

at Work Act 1974.

The electrical industry has thrown its weight behind

the new AM2 Assessment of Occupational Compe-

tence (AOC), launched by NET (National Electrotechni-

cal Training). The Joint Industry Board (JIB), Electrical

Contractors’ Association (ECA), Electrotechnical Assess-

ment Scheme (EAS) Management Committee and the

Sector Skills Council, SummitSkills have all backed the

new assessment.

“This launch is the culmination of two years of in-

dustry consultation,” said NET business development

manager, Stephen Plant. “The new AM2 has been de-

signed by the industry, for the industry. We are confi-

dent the modifications will reinforce it as the stamp to

show that its holders and their employers are capable

of providing the highest possible level of service to

clients in today’s environment.”

Steve Brawley, chief executive of the JIB says: “The

AM2 provides the industry with proof of the practical

competence of each individual at the end of their JIB

apprenticeship. The JIB is all about maintaining and

improving high standards in the electrotechnical indus-

try and the AM2 assessment is an excellent benchmark

which supports the JIB in achieving this objective. Suc-

cessful candidates can obtain their Electrician card

within the Electrotechnical Certification Scheme to ac-

credit their competence.”

Trevor Hill, development manager at SummitSkills

said: “The industry’s contribution to the updating of

this electrotechnical competence assessment has been

incredibly positive. The experience and advice of those

currently in the industry, in roles at different levels, was

used to ensure that the AM2 reflects the skills and

knowledge needed by to-day’s electricians.

Uninterruptible Power Supplies Lim-

ited (UPSL), a UK provider of power

protection solutions, has announced

it will be renamed Uninterruptible

Power Supplies Limited, A Kohler

Company, will be launching a new

website and is embarking on a

global expansion programme.

The programme, already in devel-

opment, will see the first Interna-

tional office open in Singapore in

May. Other new locations are also

planned for 2010, with China, India

and the Middle East initially being

targeted.

The statement follows Kohler

Global Power Group's acquisition of

the UK based UPS and generator

specialist in September 2008 and

signals the American giant's entry

into the European power protection

market.

UPSL managing director, David

Bond, commented on the deci-

sion:"Since joining the Kohler family

we have spent a great deal of time

identifying the right direction for the

company and examining its position

within the global UPS market. Mov-

ing forward, our strategy will see

some challenging goals being set, in-

cluding opening up several new in-

ternational markets and increasing

the company's turnover tenfold in

the next five years. However, despite

these demanding targets, we are ex-

tremely confident we have the prod-

ucts and infrastructure to meet our

objectives and significantly increase

UPSL's market share, both in the do-

mestic market and abroad.”

Talking about the expansion plans,

Yu Ming Tan the company’s new

Southeast Asia general manager, re-

marked: "With the reputation Kohler

Global Power Group brings to the

table, the decision to reflect our par-

ent's name in our international

branding will undoubtedly make it

much easier for consumers to recog-

nise and distinguish our advanced

product range. Looking specifically at

Singapore, it's vital we create clear

blue water between the Kohler UPS

brand and its competitors – we feel

Kohler's history, combined with our

product and service offering will en-

sure we can achieve this."

GLOBAL EXPANSION PLAN

� Denman Instrumentation has completed its 29th contract with

multinational power and infrastructure company, Alstom. The contract,

for commissioning and calibration at Alstom’s new power plant in

Fujairah, UAE, has been an ongoing project since early 2009. Denman

has been working with Alstom (formerly ABB before a buy out in 2000)

for nearly 20 years. The Hull-based company gained its first contract with

the infrastructure giant in 1993 working on the Killingholme power

station in Lincolnshire.

THE MAIN MAN

OPINION

HOW MANY MEN .....A study by Screwfix reveals no less than 51% of young men in their

twenties are incapable of wiring a plug. This compares with only 15%

such incompetents amongst men over 50.

Even changing a light bulb apparently leaves one in eight young

men completely stumped – whereas just 3% of we oldies are

apparently unable to turn a bayonet fitting. And when it comes to

bleeding a radiator, over half the men in their twenties would call in

professional help – compared with just (just?) 17% of their dads.

I particularly enjoy the wonderfully laconic response from the folk at

Screwfix. It goes: “Our research shows some young men struggle to

live up to the expectations of previous generations.”

NO CAUSE FOR CONCERNMy congratulations to the World Bank. It is to lend no less than $3.7bn tothe South African state-owned electricity generator, Eskom. The moneywill be used to build the Medupi power station in Limpopo province – thefirst of two giant coal-fired power stations Eskom plan to have inoperation by 2016.I am quite sure the World Bank is absolutely right to completely ignoreits own guidelines, regarding the need to ensure that carbon offsetactions are undertaken to combat the extra emissions that Medupi willcause. It is surely an absolute nonsense for the US, UK and Dutchgovernment to refuse to endorse this project, citing such “environmentalconcerns.”

After all, we have an absolute assurance from none other than theWorld Bank’s president, Robert Zoelick that, from the start, the plant “willuse clean coal technology.” The fact R & D testing for such technology isnot due to conclude, until way after both Medupi stations are up andrunning, need surely give us all no cause for concern.

GOSSIP!GOSSAGE!

The Sunday Times is not a newspaper given to understatement. Either in the sheer length of its breathlessexposés, or in the portentous nature of its accompanying editorials. Recently, it ran an enormous article“revealing” generating electricity from the wind can, from time to time, prove intermittent.This prompted an equally verbose editorial castigating windpower, which concluded with the advice it isfar better to stick with "known technologies that can deliver, like clean coal”. Coal being acknowledged tobe the dirtiest of fuels, you have to assume by this apparent contradiction the Sunday Times editor isreferring to the concept known as “carbon capture and storage”, intended to retain and store the emissionsof carbon dioxide caused by burning coal.

That being the case, the Sunday Times editor might have acknowledged that this is as yet an entirelyunproven technology. Hence the reason why the European Union is hoping to fund 12 “carbon capture andstorage” demonstration plants. It is unlikely we shall know whether these can be made to workcommercially during this decade. So, with the best will in the world, scarcely a tried and tested option!Unlike perhaps using the Sunday Times to light fires with.

NOT GIVEN TO UNDERSTATEMENT

PUZZLING POSTERS


Most advertising professionals reckon outdoor display posters

must contain very basic messages to be effective. A simple

slogan, with an eye-catching graphic. But not a whole mass of

words.

That is not a philosophy the German company E:On appears to

accept. At my local railway station, there are several large posters

which E:On have paid for. I only know this because there is a

discrete company logo at the bottom right corner.

The poster consists of a small headline at the top, which says:

“Why on earth would an energy company want me to use less

energy?” Below is a line drawing of a man reading a broadsheet

newspaper (of which only two still exist, the Daily Telegraph and

the Financial Times - and as the paper isn’t coloured pink, it must

be the former title).

But most of the poster is given over to no less than 485 words

of tightly written copy, explaining how far-sighted E;On is by

helping us to conserve energy - which I note they conflate with

dishing out million of free energy saving light-bulbs. Scarcely any

of which are ever installed.

At the bottom of the poster, is a strap line, which I admit I find

very confusing. It reads: “Helping you get energy fit. We’re on it.”

What should we conclude from this? Perhaps E.On’s media

buying skills are so great they have ensured such posters only

appear on railway platforms. Where, given the tardiness of too

many trains, there may well be many prospective readers kicking

their heels (as I was).

Or perhaps nobody is really supposed to read all the 485

words. But instead to turn away from the poster feeling that,

verbose or not, this is obviously a far-sighted deep-thinking

company, probably riddled with a fair measure of German angst.

I am genuinely puzzled. What do you think?

All those with an interest in constructing

new power stations have a great interest

in the man who has been appointed to

run the government’s new Infrastructure

Planning Commission. Because it is he

who is taking over from local authorities

the role of deciding which of these get

the go-ahead.

The man with this onerous task is one

John Saunders, an ex-banker with

absolutely no planning qualifications. But

whose main pertinent experience seems to

be as a former licenser of bouncers at the

Security Industry Association.

There are five electricity companies

hoping for a particularly sympathetic

hearing from Mr Saunders. These are

National Grid, Innogy, Powergen (now

E:On), National Power (now RWE) and

Northern Ireland Electric. And what do

these five electricity companies have in

common? I will tell you. It is John Saunders’

name on their shareholders’ register.

TEST & MEASUREMENT

Customer service and

satisfaction levels

have become a

crucial area for

electrical test

companies

FOR CONTRACTORS involved in electrical testing there

has never been a wider choice of test instruments

available.

In recent years the instrumentation industry has been

at the forefront of innovation and technical advances.

These changes have been made in recognition of the

situation for electrical companies, particularly during

difficult economic conditions, the challenge is to balance

the provision of efficient, high quality test services with a

competitive price tag and value for money offering.

The test companies that flourish will be those that

combine a fast and effective service that does not

compromise the quality of testing undertaken – and who

can build on existing customer relationships.

In fact customer service and satisfaction levels have

become a crucial area for electrical test companies. With

less work around existing relationships become even

more important. It follows that an ability to enhance

existing customer services through the provision of a cost-

effective and added-value test service can do much to

both reinforce a company’s reputation and maintain a

positive profile with influential prospects.

In addition, as well as a wide variety of testers

available, the ability to provide a seamless link between

test instruments used in the field and central test record

systems that produce test certification and other reports

also takes on even greater importance.

The good news for large and small contractors is

advances in test instrumentation mean a range of options

are available to meet specific test needs – and budgets –

for periodic electrical installation testing or portable

appliance testing.

IN 17TH EDITION TESTINGThe HSE’s Guidance Note GS38 provides guidance to

electrically competent people involved in electrical testing,

diagnosis and repair. The note identifies three main test

instrument categories – those that detect voltage, those

that measure voltages and those that measure current,

resistance and (occasionally) inductance and capacitance.

The first named forms an essential part of the

procedure for proving a system dead before starting

work, whilst the other categories are more concerned

with commissioning and testing procedures and fault

finding.

Guidance note GS38 provides details of the risks

associated with the use of unsatisfactory test equipment

and includes a list of safety precautions and requirements

all professional electricians should be aware of.

However, in terms of selecting appropriate 17th Edition

test instruments, electrical contractors are broadly faced

with a choice between ‘multifunction/combination’ testers

or single application specific testers.

As the name implies the latter are designed to carry out

one specific function – RCD testing, insulation, earth

resistance etc – and the ‘all in one’ type testers are single

units designed to carry out a wide range of tests

including earth loop, insulation resistance, continuity,

RCDs etc.

Choice invariably depends on the scope of work to be

carried out, but increasingly it is the multifunction testers

JIM WALLACE OF SEAWARD, EXPLAINS HOW ADVANCES INTEST TECHNOLOGY HAVE INCREASED THE RANGE OF TESTINSTRUMENT OPTIONS AVAILABLE TO CONTRACTORS


SMARTER CHOICESin electrical testing


Multifunction testers

have become the

preferred tools of the

trade for those

involved in 17th

Edition testing

that have become the preferred tools of the trade for those

involved in 17th Edition testing. This is for both practical

reasons, in terms of using one meter constantly rather than

swapping and changing between testers, and also for

budget considerations – buying, maintaining and

calibrating one combination tester is invariably cheaper

than buying three separate ones.

Multifunction 17th Edition testers carry out the required

circuit tests and display the test reading for transfer onto

the test certificate manually or alternatively, readings can

be recorded on a PDA and transferred to a desktop

application for certificate printing. Some testers are also

linked with smart phone and portable laptop applications

which work in the same way by gathering test data

collected in the field for subsequent transfer onto a master

certificate.

The latest generation 17th Edition testers eliminate the

use of intermediary devices by storing a replica of the test

certificate within the tester so test data can be

automatically incorporated onto the certificate as testing is

undertaken.

In this way the instrument combines the functions of a

multifunction test instrument and data logger. When

inspection and testing is complete, the certificate held

inside the tester can be transferred to accompanying PC

software for the completion and print out of formal

certificates.

As a result the time consuming (and therefore costly)

practice of recording results on paper, a dummy certificate

or a PDA is avoided. In addition, because the tester warns

the user if any certificate fields appear incomplete or

invalid, verification of data can be carried out on site

immediately and without return visits.

Recently the concept on ‘on board certification’ in testers

has been extended with additional features aimed at large

testing organisations or the testing of large premises.

For example, the moist advanced 17th Edition testers

now have the ability to upload certificates generated on a

PC into multiple testers. This is particularly useful in

situations where a number of test personnel might be

working on the same large installation, such as a hospital

development or shopping mall and enables specific test

work to be allocated to a number of engineers very easily.

Once testing has been undertaken, the software

enables test results downloaded separately from

different testers to be merged into a single certificate

for the premises concerned.

Another new feature is the ability to ‘clone’ certificates

from an existing master document. This allows the user to

select an existing certificate and use this as a template to

create multiple certificates for identical or similar electrical

installations.

The cloned certificates will contain all of the distribution

boards and circuit details held in the original and therefore

represents an easy way of generating certificates for, say,

20 or more houses on a street which all have the same

electrical configuration.

In these combined testing and certification testers, all

data transfer between the PC and the instrument can be

achieved easily using Bluetooth connectivity. This means a

certificate can be uploaded to the tester, the required test

and inspection carried out and the information

downloaded to a PC and the final certificate printed

directly onto pre-printed NICEIC, ECA, ECA Select or Napit

stationery.

With such a wide range of test instruments and

accessories to choose from, electricians and contractors

involved in 17th Edition electrical testing can be sure the

right test package solution is available to meet their

specific needs and budget.

In recent years substantial technical development has

gone into the development of new test instrumentation so

the ‘tester’ can now be used in a much more effective

manner – improving operational efficiencies, adding value

to the test process and enhancing customer relationships.

TEST & MEASUREMENT


TEST & MEASUREMENT

ONE OF THE BIGGEST challenges substation control

engineers face, is not how to implement interlocking

schemes based on IEC 61850, but how to test them. The

problem is particularly acute, because at present IEC 61850

is being more widely used for interlocking than it is in

protection applications.

Of course, options do exist for testing IEC 61850

interlocking schemes. However, these almost always involve

the use of protective relay test set that supports IEC 61850.

This approach, however, is far from ideal. The first concern is

that, in most cases, control engineers are not

protection engineers. They are

unlikely, therefore, to be familiar with

the operating a protective relay test

set. They could, of course, learn, but

that’s a pretty steep learning curve for

something that is not central to their

work.

Another issue is protective relay

test sets are necessarily costly, since they

incorporate high-performance precision amplifiers and other

elements that are expensive to develop and produce. Yet

these are not needed for testing interlocking schemes, so

using a relay test set in this application is not only overkill, it

also needlessly ties up expensive capital equipment.

It’s clear there is a pressing need for a reasonably priced

instrument that is simple to use and provides all of the

facilities needed for testing IEC 61850 interlocking schemes,

but does not incorporate the expensive extras needed for

protective relay testing.

It’s not difficult, in principle at least, to imagine how such

a test set would work. First of all, it would monitor the

Goose messages IEC 61850 installations use to

communicate and it would convert them to the ordinary

type of on/off binary signal that control engineers are used

to working with in non-networked installations.

The test set would also be capable of working in the

opposite direction. That is, it should take signals from

ordinary contacts and convert them into appropriate Goose

messages. In effect, a test set of this kind is simply an

interface between the Goose messages on the bus and the

electromechanical world of the control engineer.

Of course, there’s rather more to be considered than this

very basic overview initially suggests. For example, the

conversion between Goose messages and binary signals

must be fast enough so as not to materially affect the

timing of the interlocking system. In practice, a conversion

time of less than a millisecond, which is achievable with

careful design, will be fast enough to satisfy the most

demanding of requirements.

Next, it is clearly necessary to be able to associate

particular Goose messages with specific inputs and outputs

on the test set. This is best accomplished with software but,

if it is to be intuitive and easy to work with, the software

needs to be carefully designed. Further refinements can also

be envisaged. For example, LEDs that provide instant visual

confirmation of the state of the instruments binary inputs

and outputs would be an important benefit for users.

The ideas mentioned in this article have driven the

development of Megger’s new Goose Message Interface..

This embodies a number of unique technical features for

which patents are pending, and offers the most efficient

and cost-effective solution currently available to the

challenge of testing IEC 61850-based substation interlocking

schemes.

That is, however, by no means the limit of the

capabilities of the Goose Message Interface. While it may

not be particularly interesting to control engineers, the

unit can also be used to adapt a conventional protection

relay test set so that it can be used to test IEC 61850

protection schemes. This is a big benefit for users that

already have protection relay test sets – whether they are

units supplied by Megger or by others – as it is offers a

very straightforward and cost-effective upgrade path.

It also creates an attractive option for consultants and

smaller organisations who can now purchase a Goose

Message Interface and a modestly priced relay test set, to

cover all their relay and interlocking test requirements for

both conventional and IEC 61850 schemes.

Equipment that allows convenient and dependable

testing of IEC 61850 interlocking schemes has, until now,

been difficult or even impossible to find. This situation

has now been addressed by Megger’s Goose Message

Interface, an instrument that provides the added bonus

of facilitating the testing of IEC 61850 protection

schemes.

CMC 850The CMC 850, shown in Figure 1, is the

first test set dedicated to IEC 61850. It

focuses on the described real time

communications utilising Goose and

sampled values. The device is controlled

by the well proven Omicron Test Universe

software. Additional features can be

accessed through a new web interface.

The device was developed for the IEC

61850 standard, working without classical

secondary values. The result is a small

and light weight device which is compact

and easy to carry having a width of just

80 mm and a weight of only 1.7 kg.

Conventional I/Os and analog outputs are

not available.

The capabilities of CMC 850 regarding

IEC 61850 are the same as their ‘big

brothers’ CMC 256-6, CMC 256plus, CMC

353, and CMC 356:

The CMC 850 has the capabilities of

simulation and subscription of up to 360

data attributes up to 128 Goose

messages, and the generation of up to

three sampled values streams (one

stream contains 4 currents and 4

voltages)

The supported sampled values version

and more specifically the option with 80

samples per cycle is in accordance with

the implementation guideline of the UCA

International Users Group [2], (widely

known as "9 2LE").

ADDITIONAL FEATURESThe device provides additional built-in

functionality, which cannot be found in

other CMC test sets. These functions are

accessed with a normal web browser.

One feature is the visualisation of received

sampled values in a multimeter or

oscilloscope view, seen in Figure 2.

Subscribed sampled values are used to

calculate the phasors, which are then

provided as synchro¬phasors according to

IEEE C37.118 [2]. Recorded network traffic

(in PCAP-format) can be played back

through the device.

TIME SYNCHRONISATIONTime synchronisation is an important issue

when dealing with sampled values. The

CMC 850 is delivered with the CMIRIG-B

interface which allows synchronization to

IRIG-B or a pulse-per-second (PPS) signal.

Time stamping of Goose messages and

sampled values is made possible through

the use of Net¬work Time Protocol (NTP)

or Precision Time Proto¬col (PTP)

according to IEEE 1588-2002, V1).

SEGREGATION OF NETWORKSThe CMC 850 is equipped with two

independent Ethernet-Ports (Figure 3).

Each of these ports can be used for

controlling the test set with a local PC, or

for sending/receiving Goose and/or

sampled values. This allows maximum

flexibility in the configuration and a

segregation of IEC 61850 data combined

with the control protocol for the test set.

APPLICATIONSThe CMC 850 test set is perfect for use in

the IEC 61850 environment. It is

particularly suitable for use in the

development of intelligent electronic

devices (IEDs) and for factory and site

acceptance testing. The device is also ideal

for demonstrations of IEC 61850 IEDs and

for training purposes.

SUMMARYOmicron was the first vendor to provide

testing solutions for IEC 61850. This

device, equipped for current and future

testing in the IEC 61850 environment, is

the result of vast experience, technical skill

and collaboration with international

standardisation committees.

FACTORY AUTOMATION

AS MANUFACTURERS converge data between the plant

floor and business office, machines that leverage the

power of these domains have become a machine

builder’s competitive advantage. Information-enabled

machines arm manufacturers with a valuable resource

for gaining critical operational insight they need in

today’s knowledge-based business environment.

While helping to differentiate machine builders in the

marketplace, information-enabled machines have

another advantage: they help machine builders reduce

total cost to design, develop and deliver those

machines to the market. As the economy has cooled,

demand for information-enabled machines has heated

up. Why?

Machines with embedded intelligence offer an

innovative way to wring more productivity out of the

manufacturing operation. That’s because these

machines generate data and diagnostics that leads to

meaningful analysis. That analysis helps control

engineers precisely identify how to improve their

processes.

Industry standards helpFortunately for machine builders, industry standards

such as EtherNet/IP have made building these

sophisticated machines easier than ever. The

EtherNet/IP protocol allows users to control, configure

and collect information over the same network while

still having the ability to support standard Ethernet

functions such as e-mail, web page browsing and data

sharing.

With such broad capabilities and performance, Ether-

Net/IP can serve the functions of multiple network

levels. This converged network infrastructure simplifies

a machine’s design, and in turn helps machine builders

lower their design costs.

The savings are even greater for machine builders that

pair EtherNet/IP capabilities with controllers that have

advanced text string handling instructions. With

supporting hardware, EtherNet/IP-enabled controllers

can initiate e-mails to multiple addresses to deliver

reports that maintenance personnel can use. For

example, maintenance can check alarms, provide

manufacturing proficiency data to management or

deliver machine diagnostic data to the OEM.

This deep understanding, along with remote access

capabilities, helps keep machines running. Embedding

intelligence-gathering devices into machines helps

machine builders provide customers with self-diagnostic

equipment that can predict and prevent failures. This

improves productivity and can reduce repair costs.

Some machine builders provide an overall equipment

effectiveness (OEE) report and other advanced

information displays via the human-machine interface

(HMI), giving operators instant insight to these

diagnostics. In addition, the end user can relay machine

condition information back to the machine builder for

value-added monitoring and analysis services.

Technicians can then securely connect to the machine to

monitor critical parameters and take action before a

machine fails.

Savings beyond the machineMachine builders traditionally designed equipment with

a focus on meeting the needs of the controls engineer.

However, they also need to consider the needs of IT

professionals. At Rockwell Automation we have

developed tools, technologies and resources to help

OEMs both address and facilitate this top-floor to shop-

floor integration. New products help machine builders

manage real-time information flow by reducing network

latency and jitter. Modular managed switches can now

address the network convergence activities by offering

features for both IT professionals and control engineers.

Fixed managed switches can also give users cost-

effective control over their Ethernet/IP network, which

can work especially well for applications with small or

highly distributed network devices or devices connecting

to the controller.

Achieving high performanceInformation-enabled machines are essential for giving

operators and managers the insight they need to

reduce their overall cost to design, develop and deliver

these sought-after machines. Machines that effectively

bridge the gap between the shop floor and the top floor

ultimately help OEMs meet customer demands for high-

performance machines.

ADVANCED AUTOMATION FOR FOOD PROCESSING

On a weak supply, a normal fuse

may take two to three seconds to

clear, which is ample time to inflict

some serious damage on a drive.

Semiconductors, such as those used

in the rectifiers and inverters of AC

drives, are heated rapidly by excess

current, so even a short exposure to

overload can be very damaging.

Drives differ from other equipment

in that they have large amounts of

energy stored in the DC link

capacitors. With the DC link isolating

the motor from the supply, protection

for the motor is effectively provided

by the drive. However, the rectifier

and associated components must be

protected at the supply side.

Fuses and circuit breakers measure

the current passing through and

therefore are very sensitive to the

effective fault level of the supply for

their clearance time. As well as

fitting the recommended rating of

fuse or circuit breaker, the user must

be careful to calculate the clearance

time; the required clearance time

will be given in the drive

manufacturer’s data. Typically,

clearance times of 500 mS will be

adequate, but times as short as 100

mS may be needed. Such short

clearance times may necessitate the

use of high speed fuses, also known

as semiconductor fuses, to ensure

appropriate protection.

While the fuse or circuit breaker

selected may be sufficient for the

average network supply,

consideration must also be given to

alternative supplies, such as

generators which have much lower

fault levels, to ensure that the drive

has adequate protection at all times.

If using a residual current device

(RCD), the role of the radio frequency

filters must be considered.

These filters are used in most

drives to mitigate conducted

emissions. By the nature of their

design, they have an inevitable earth

leakage. In addition, the drive will

always exhibit a very small level of

DC in its supply, which can prevent

some types of RCDs from tripping. If

using an RCD, the drive should be

fitted with low leakage filters.

However, the choice of RCD is still a

difficult area and the RCD

manufacturer should always be

consulted.

ENCLOSURES

THE VARIOUS enclosure materials available have their

strengths and weaknesses and in order to specify the

most appropriate material, these must be fully

understood. In addition, the importance of the right

quality enclosure is critical. The role of an enclosure is to

protect valuable electrical components and personnel

and it just doesn’t make sense to save a few pounds by

purchasing an inferior product to protect high value

systems. A substandard enclosure could result in leaks,

damage to equipment, and possibly even become a

hazard to the public. If this happens not only is the user

faced with the cost of replacing the enclosure, there is

also the cost of changing any damaged components,

downtime and possible litigation.

It is critical the same level of time and investment goes

into choosing the right quality enclosure, in order to

reflect the time and money spent in developing the

system it contains and the system(s) it is connected to.

Choosing the right material for the job is also an

important consideration. Buying a high quality enclosure,

but in the wrong material, can be a costly mistake.

Depending upon the application and the preference of

the customer, there are three common materials which

enclosures are manufactured from: mild steel, stainless

steel and GRP. But regardless of the material used, each

enclosure should be chosen to suit the specific

application they are intended for and this includes having

the appropriate IP rating. IP ratings are defined in the IEC

60529 standard for degrees of protection provided by

enclosures, published in the UK as BS EN 60529.

The degrees of protection are specified by the letters

IP, followed by two or more digits. The first digit (1 to 6)

depends on the protection given by the enclosure to

equipment within it against the ingress of objects, and

also the protection of persons against contact with live

parts of equipment within the enclosure. The second digit

(1 to 8) relates to the protection of equipment against the

harmful ingress of water. Either digit can be replaced by

‘X’ for an unspecified condition.

Optional supplementary letters can be used to specify

only the protection of persons against access to

hazardous parts, and to stipulate special conditions, such

as use for high-voltage apparatus or under specified

weather conditions.

In general, a higher number represents better

protection, although specifiers should be aware this isn’t

always a guarantee, as sometimes an enclosure might,

for example, pass the tests for IP67 but not to a lower

rating such as IP65.

It is important specifiers fully understand the

conditions of use for an enclosure, as simply specifying a

high IP rating does not necessarily mean it is right for the

job. The designations refer to the ability of the enclosure

to pass the tests under controlled conditions, not to its

ability to withstand influences such as weather, sunlight,

corrosion, or extremes of temperature. A product can

meet the highest level for protection against ingress of

water, yet be subject to rusting, so customers must make

clear what they are actually expecting from an enclosure

rather than relying solely on an IP rating.

In addition to IEC (BS EN) 60529 there are two other

standards widely used for enclosures; IEC (BS EN) 62262

‘Degrees of protection provided by enclosures for

electrical equipment against external mechanical impacts

(IK code)’ and IEC (BS EN) 62208 ‘Empty enclosures for

low-voltage switchgear and control gear assemblies -

general requirements.’ BS EN 62262 uses the letters IK

followed by the numerals 00 to 10 to specify the

enclosure’s ability to withstand mechanical shock

including direct impact.

These ratings are used across all materials including

mild steel –the UK’s most popular choice. This type of

enclosure is suitable for most indoor applications. With IP

ratings up to IP66 and a high IK rating, it is robust and

SPECIFIERS MUST ASSESS ENCLOSURE CONSTRUCTION BEFORE SPECIFYING PRODUCTS AS

THE INCORRECT CHOICE CAN LEAD TO SIGNIFICANT AND COSTLY CONSEQUENCES. THEY

SHOULD ALSO MAKE SURE THEY FULLY UNDERSTAND THE SYSTEM OF IP RATINGS, TO AVOID

INCORRECT CHOICES AND SPENDING MORE MONEY THAN NECESSARY. HERE, DARREN

strong in many environments. The fact that it is easily

modified is another reason why it has remained a popular

choice for so long. However, specifiers are gradually

realising its weaknesses. Mild steel has poor anticorrosion

properties if the material is not treated, and this treatment

is usually expensive. In addition, cut-outs made after

painting must also be protected, adding yet a further cost.

As an enclosure material mild steel still has its place.

For general purpose enclosures, either indoors or in

industrial and commercial premises, it is a cost effective

solution but the fact it corrodes so quickly makes it an

unsuitable choice for any external applications.

Stainless steel has been a popular material choice for

decades, typically used within the food

manufacturing, food processing and

pharmaceutical industries as well as for

most external applications. It provides

the same benefits as a mild steel

enclosure but with greater longevity in

aggressive environments. It is also rust

resistant, however depending on the

grade and the environmental conditions, tarnishing and

corrosion can occur. Stainless steel also has its own

natural finish and so requires no further treatment.

GRP is best suited to outdoor applications as it does

not corrode in damp/wet conditions, even when exposed

to sea salt. It also offers excellent protection against UV

rays and therefore it won’t discolour. Being an insulator it

offers extra peace of mind on public access sites and so

GRP is fast becoming a major competitor to steel with its

insulation, strength and corrosion resisting properties

over a temperature range from -50oC to 150oC.

GRP enclosures are designed for the wide variety of

aggressive applications in which they are used. In

addition to the material, which is double insulated, self-

extinguishing and halogen free, there are a number of

anti-vandal features which make unauthorised access

difficult. The list of industries that now accept GRP

enclosures is growing and includes security, airports,

highways, rail, utilities, telecoms and agriculture.

It is also important to remember, especially when

considering harsh environments, high IP levels are not

necessarily an indication of a product being

weatherproof. Other design features such as canopies

also contribute to the enclosure providing the correct

level of protection.

IP ratings are invaluable in ensuring enclosures meet

the correct standard however it is not always straight

forward, as highlighted by one of today’s most common

misconceptions – requests for enclosures rated IP69K. At

first sight, when you consider the rules for IP codes there

is no such thing, since this rating is not mentioned in any

of the standards mentioned above. In fact it stems from a

German national standard developed for use specifically

in the automotive industry.

DIN 40050-9 adds to the IEC 60529 rating system with

an IP69K rating for high-pressure and high-temperature

wash-down applications. The IP69K test specification was

initially developed for electronic equipment on road

vehicles, but has also been used in other areas such as

the food industry, where the use of pressure washers is

common.

This standard is purely a German national one and

currently has no real meaning in the UK or other

countries, as it doesn’t feature as part of a British or

International standard. A project is now underway to

incorporate its requirements into IEC 60529 but initial

attempts by various test houses found the test

equipment and procedures were not precisely defined

by the DIN standard. This means they do not give the

same result when performed by different test houses,

and so cannot be compared. Some research has resulted

in a proposal to modify IEC 60529 to include the

designation IPX9, but this is still at an early stage, and

needs more work before it can be published as an

amendment to the standard.

In the meantime buyers of enclosures should be aware

that ‘IP69K’ products from different manufacturers may

differ, and might not even pass the tests for IPX5. They

should also remember that even the IEC 60529 tests are

fairly short, up to 30 minutes for IPX7, although longer

immersion can be agreed as part of IPX8. As a result they

do not define the enclosure’s ability to withstand long-

term influences such as weather conditions. It is also

often forgotten the ‘water ingress’ tests do not specify

that no water must enter; they allow water to enter but

not in quantities that are considered to be ‘hazardous’,

which of course cannot be determined without knowing

what apparatus will be within the enclosure.

Today’s enclosures offer a wide choice of materials

and the breadth of products available is always

expanding but specifiers and designers should remember

that correct material specification is vital in achieving

product longevity. And it is impossible not just to choose

an enclosure with the highest IP rating and expect it to

do any job, in any environment. Specifiers need to

carefully assess the conditions of use and prescribe the IP

rating that is most appropriate and importantly one that

is recognised by IEC or British Standards, as well as

choosing the appropriate material for their enclosures.

Electric arc is one of the most deadly and least understood hazards of

electricity. The outcome of an arc flash can be disastrous but most

people are unsure how to deal with the risks effectively.

An electric arc is an ongoing plasma discharge through normally non-

conductive media such as air and occurs when there is a short circuit

through the air between conductors or conductors and the ground,

resulting in hazards including exposure of workers in front of the

electric arc to extremely high temperatures, ultra violet light, toxic

smoke and fumes and fast moving debris. This can result in burns,

blindness, lung damage, hearing damage and death to not only the

people working on the electrical equipment but also to people located

nearby. J & K Ross has developed the Arc Flash Protection Programme

to help companies assess the potential risks of arc flash, carry out the

necessary checks and implement improved procedures if necessary.

This may include the implementation of personal protective

equipment (PPE).

Risk Assess

People working in the vicinity of or at energised parts of electrical

systems need to be protected against the effects of possible electric

arcing. All such work needs, first of all, to be subjected to a risk

assessment. This will enable the risk from arc flash to be identified,

determine who might be harmed and form the foundation of the

next steps.

React

The severity of the thermal effect of an arc flash is defined as

incident energy, which may arrive at the worker at a given distance

from the electric arc, and is measured in calories/centrementre²

(cal/cm²); it is the energy that a victim, at a given distance from the

electric arc, could receive to the surface of their clothing. In cases

where the clothing is not sufficiently protective against the heat and

radiation generated by an electric arc, the victim may suffer serious

skin burns. An arc flash study will tell you the incident energy likely

to occur due to the flashover, or in simple terms – how big is the

bang? Following a risk assessment it may be necessary to carry out

an arc flash study to establish the potential incident energy and

then suitable risk control measures can be explored. Most

importantly, there will be an evaluation that will highlight the cases

of low risk, those which will need other protective measures and

those areas where there is a great danger to workers who engage

in live working activities or are working on or close to energized

electrical equipment.

Realise

Based on the outcome of the risk assessment and arc flash study,

control measures need to be implemented to remove, eliminate or

reduce the risk. These measures should adhere to the following

hierarchy of risk controls:

1. Elimination– de-energise equipment before beginning work

2. Minimisation – investigate trip times or fuse ratings and explore

possibilities for faster disconnection times.

3. Information and training – educate workers to ensure their

competence

4. Control the risk – properly maintain equipment and substations to

ensure safe working systems

5. PPE – issue as a last line of defence to help prevent burn injury to

workers

If it is still necessary to protect workers, providing all other practicable

measures have been taken to minimise the risk, adequate PPE should

be issued as a last line of defence. PPE can help protect against the

thermal effects of an arc flash but it doesn’t prevent the accident from

happening in the first place.

Flame resistant (FR) clothing can be rated based on its Arc Thermal

Performance Value (ATPV) in cal/cm2. To properly protect a worker, the

ATPV rating of the FR clothing must exceed the calculated prospective

incident energy caused by an arc flash onto the worker at a given

distance from the electric arc. J & K Ross, in conjunction with DuPont

Personal Protection, has developed ARCBAN® a range of CE certified arc

flash protective garments made from Nomex®. The ARCBAN® range of

garments are designed to be layered to offer the relevant level of

protection when required for different jobs with different possible

incident energies and ensure that the worker is not restricted or

compromised with cumbersome clothing, which would have been

selected based on being appropriate for the worst case situation.

Layering the garments can help to increase the ATPV levels due to the

air gaps in between the garment layers. It can also help with matching

the hazard and risk with the appropriately designed PPE resulting in the

wearer having more fit for purpose and comfortable solutions for the

relevant hazardous environment.

The ARCBAN® range incorporates DuPont™ Nomex®, an inherently

flame resistant meta-aramid fibre that does not melt, drip or support

combustion in the air. The thermal behaviour of Nomex® is due to its

molecular structure and not by applying a flame retardant chemical

substance to the fabric, yarn, fibre or polymer. This means that Nomex®

offers permanent protection that cannot be washed or worn away. The

ARCBAN® range offers head to toe solutions providing various levels of

electric arc protection.

SWITCHGEAR TECHNOLOGY

THE TERM ‘HYBRID’ refers to the combination of both

conventional air insulated switchgear (AIS) and the newer

metal-clad gas insulated (GIS) switchgear. This hybrid

solution, as found in ABB’s Pass MO design – rated up to

170 kV, uses existing, tried and trusted GIS components

together with a conventional and extremely reliable AIS

bus to connect the various hybrid modules. All the

necessary substation switchgear bay functions, including a

circuit breaker, one or more combined

disconnector/earthing switches, bushings for connection

to single or double busbar systems and a current

transformer are integrated in one compact module,

eliminating the need for separate pieces of equipment for

each function.

Hybrid advantagesThe advantages of the hybrid switchgear design include:

� AIS busbar: The AIS busbar is relatively inexpensive

while offering proven reliability.

� All live contacts in SF6: Experience has shown AIS dis-

connector switch contacts require relatively high levels

of maintenance, while experience with GIS is exactly the

opposite. The use of SF6 technology makes the hybrid

switchgear virtually maintenance free, this combines

with a high level of reliability to ensure a lower global

life cycle cost.

� Fewer switching elements: Use of GIS technology allows

rationalisation of switching elements.

� Factory pre-assembled and tested: The hybrid modules

are fully pre-assembled and tested in the factory. This en-

sures a higher quality of finished bay than if it is assem-

bled under site conditions, minimises installation time on

site – typically two days per bay, reduces the possibility of

delay due to adverse site conditions and there is less

need for skilled resources on site.

� Monitoring and on-line diagnostics: The integrated nature

of the plant facilitates the use of electronic monitoring

and on-line remote diagnostics.

� Substation modularisation: A modular approach to sub-

station design offers cost and time savings during the de-

sign and construction phases. The use of standardized

components reduces the number of possible variations

and hence the risk of design errors. More predictable

costs also offers a higher level of confidence in the proj-

ect estimation process.

� Space saving and reduced civil works: The hybrid design

can save up to 70% of the space normally required for a

conventional AIS substation, while also reducing the need

for civil works such as foundations, steelwork and cable

trenching operations

� Combined disconnector/earthing switch: Pass MO is

equipped with a combined disconnector/earthing switch.

The mechanism has a minimal number of mechanical

components and is intrinsically reliable and maintenance-

free.

� Circuit breaker: The Pass MO circuit breaker is a single

pressure interrupter that operates by means of the well

known selfblast principle. The energy for interrupting cur-

rents is partly supplied by the arc itself, this reduces the

energy the operating mechanism needs to provide by

around 50% compared with a conventional puffer type

circuit breaker.

� Versatility: The Pass MO range offers a series of modules

for HV substations including: single bus bar (SBB); double

bus bar (DBB); double circuit breaker (DCB). It can also be

installed as a high voltage bay on a mobile truck for use

in emergencies or if work has to be carried out on exist-

ing HV bays.

� Transportation: The Pass MO fits into a standard truck

container and does not require any packaging. No special

arrangements are needed for shipping and transporta-

tion, and once on site just a simple 30° rotation of the

outer poles is needed for the final layout.

Tight fit for Breamish Street substationWell over 2,000 Pass MO bays have been installed

worldwide. Following its approval by the ENA (Energy

Networks Association) one of the first UK projects to feature

the range was CE Electrics UK’s new 66/11 kV Breamish

Street substation on a brownfield, urban site in Newcastle-

upon-Tyne.

The new primary substation is helping CE Electric UK to

deliver an additional 18 MVA of firm capacity to meet the

growing demand for additional power, and need for load

transfer, created by the significant urban redevelopment

programmes on the north bank of the River Tyne. The

restricted space available presented a particular technical

challenge, since the Breamish Street site is not only compact

in size, it is also hemmed in on all four sides by a hotel, a

pharmacy, a residents association and the 18th century St

Ann’s church.

The space-saving capability of the design has been utilised

to construct a new substation comprising two 66/11 kV

15/30 MVA CER transformers, a 66 kV in/out unit and a 13

panel 11 kV switchboard. A 66 kV feeder unit has also been

installed at Fossway, the closest CE Electric UK substation.

Providing vital construction space at ReadingHybrid switchgear has also provided an innovative interim

solution for the new Scottish and Southern Energy (SSE) 132

kV indoor GIS substation at Reading, currently under

construction by an ABB and Balfour Beatty consortium. The

site presented a particular challenge as it was already

completely full with time expired AIS switchgear that needed

to remain in service until the circuits could be transferred to

the new substation.

At first, it appeared the only possibility would be to extend

the site onto the local, heavily wooded, green space to offer

the additional room needed for the construction of the new

indoor GIS building. However, extending the site would have

involved considerable planning time and expense and

significant project delays.

An innovative alternative was found by using ABB

switchgear as a temporary measure to provide additional

space to enable the new GIS building to be built within the

existing site footprint. Firstly, ABB dismantled the generator

circuit breakers that used to serve the old North Earley power

station, which was demolished some years ago. This freed

up just enough space to install the Pass MO modules to take

over the operation of the AIS circuits at the far end of the

site. This enabled the old AIS switchgear to be dismantled to

make room for the new GIS substation. After all the circuits

have been transferred to the new substation the Pass MO

modules will be removed.

ARC FLASH

FOR ONE THING, the 13A kettle socket will be switched and

most people would flick the switch first before withdrawing

the plug. The industrial wall socket is commonly unswitched,

or just with a separate rotary isolator fitted adjacent to the

socket. This looks like an after-thought to protect the socket

user by providing an isolator nearby and hoping it gets used.

It depends on the isolator being operated before the plug is

withdrawn from the socket to ensure the circuit is no longer

live – hardly a fail-safe solution.

The consequence of pulling industrial plugs live out of

sockets can simply result in the required disconnection of the

electricity supply, but a much more serious outcome can be

severe burning from electrical arcing or

molten metal, usually brass – the metal

widely used for plug and socket contacts. The

fact that often nothing happens to the user

when the plug is pulled out can lead to a

false sense of security and risks the action

becoming routine or entirely normal and, as

such, one of those things we don’t think

about when we do do it. Things can become

even more dire if there is a fault in the

plugged-in equipment - perhaps a locked

rotor - then the danger of drawing an electric

arc with the plug is extremely high.

Preventing this outcome should be a

corporate priority.

It’s all in the designThe common industrial plug and socket

design employs a brass pin fitting into a brass

tube. Somewhere along this tube the male

pin will make contact with the tube although

not throughout the entire length of the tube –

a forced fit. The 16 and 32A versions are

manageable, but the 63 and 125A versions

test the strength and guile of the user.

Some socket versions offer an interlock to prevent live

pull-outs but these don’t always withstand the physical

frustration of the user trying to disconnect the

equipment. The common result of repeated plug

insertions and withdrawals is contact wear and

loosening. Loose contacts lead to overheating which

leads to oxidization and eventual failure.

The abuse plugs and sockets seem to attract affects their

serviceability. Conductor terminal screws loosen because

nothing prevents them from loosening. The culprits are

movement, thermal cycling and vibration. The cable entry

point into the plug is often inadequate, forcing extra strain

onto the conductor terminals themselves whilst the cable

gland works loose and migrates up the cable sheath to

perform no role whatsoever.

If there is one application where duty holders are

sensitive to these failings, it is the transport industry –

since refrigerated lorries must (increasingly) plug in

overnight to cut down on noise pollution, engine wear

and tear and fuel costs. It is common to see 415VAC 32A

coupler sockets lying around on the tarmac suffering from

the problems listed above but also quite possibly in or

close to a pool of water. The RCD-protected socket posts

will be at various angles having been reversed into by the

trailer. The pin and sleeve design cannot offer a switched

coupler socket thus trailers can be unplugged live with all

the inherent dangers.

So what’s the alternative?The decontactor socket design approaches the contact

problem head-on by using butt contacts instead of force fit

types. The concept is it is safer to throw a switch before

disconnecting industrial electrical plant and so the

decontactor has an integral switch mechanism. So far it’s a

plug and socket and a switch. But once the switch

mechanism has been operated the isolator element comes

into play. A decontactor is then a plug and socket, switch and

isolator in one product – all the elements needed for safe

electrical work practices.

This 3-in-1 design is made possible by the use of spring-

loaded butt contacts. The silver-nickel tipped contacts mate

head-on so there is no wear, no forcing of one into the

other and disconnected by pressing a socket latch.

Conductors are prevented from loosening by an anti-

vibration terminal design. Pressing this latch is the only way

to release the plug. This is particularly important if an

extension lead is used. Holding the plug in one hand and

the coupler socket in the other constitutes an ‘across the

heart connection’. As the decontactor is a load-break

device, the plug is already dead before it can be removed

from its socket.

It’s the simplicity of design that makes the decontactor

such a versatile product giving the user the benefits of

flexibility and above all safety on the shop floor.

Flexibility comes from the ability to have previously hard-

wired equipment pre-plugged ready for easy re-location to

suit production needs, from having equipment isolated

quickly and safely by multiskilled staff and from the ability to

take single phase supplies from three phase decontactor

sockets. Motors fitted with decontactors can be replaced in a

fraction of the usual replacement time.

User safety is provided ultimately by the electrical

performance of the product. As an example, the 20A rated

decontactor was successfully subjected to 10kA withstand

and close-on tests - 80A delayed fuse, power factor 0.49 at

480VAC. Because the contacts close onto each other

immediately, the current flows and, in the case of closing on

a fault, trips the protection (ie. the fuse or circuit breaker).

Each socket contact has its own arc chamber and the

socket is fitted with a safety shutter to prevent access to the

contacts. As expected, sockets can be padlocked off to

provide visible isolation. Most versions offer auxiliary contacts

for controls or signals if required.

Reducing risksInstilling safety procedures into the workforce is a fulltime

job. Staff turnover means constant vigilance is required,

particularly when the command of English is limited.

Cleansing regimes, where required, remain unfriendly to

electrical equipment particularly to sockets that are on the

front line.

The decontactor, as a supply socket or motor disconnect,

offers a much improved level of safety to users, backed up

with positive test lab results, compliance to BS EN60309-1

(industrial sockets), BS EN60947-3 (air break switch)

standards AC22, AC23 & AC3 and ultimately the Low

Voltage Directive.

Ground points are required to create a safe electrical network insidean aircraft - when it flies through dry air it gets statically charged, sowhen it lands this needs to be safely discharged through the ground.

After that, the ground personnel can maintain the aircraft safely. It isimportant that these ground points havespecific standards because, for example,when refuelling the aircraft there couldbe spark-ignition due to residualcharge.

CHASING SHADOWSTridonicAtco has supplied its LED's for Chasing Shadows, a collaboration betweenPeter Pritchard of lighting design consultancy Pritchard Themis and his wife, textilesartist Eleanor Pritchard.

The concept was to bring forest inside, for all the animals in glass cases around themuseum. 66 illuminated trees were created and hung amongst the antlers of theGrand Trophy Room; they represent a woodland, sealed and preserved ‘behind glass’.These trees were made of made of paper that was burnt and worked into by Eleanorto resemble birch bark and then sealed into clear acrylic tubes.

A white Tridonic LED within the base of each tubedelicately illuminated the paper and created a ghostly forestof light. A lighting programming system then gave life to thescene, with sudden flits of light, or slower, more menacingchanges in light levels set to suggest a living presence,watching from the trees and moving around, but never fullyglimpsed.

PROJECT SPECIFIC TESTING SERVICEEllis Patents has launched a project specific testing service that it says will remove any

uncertainty about the ability of cable cleats to do the job they have been specified for.The cleat manufacturer had previously gone on record calling for compulsory third party

certification of all cleats, but says that a lack of understanding about the process has resultedin products continuing to be incorrectly specified.

The company’s managing director, Richard Shaw commented: “Third party certificationreally should clear up any doubts about a cleats ability to withstand the maximum force it islikely to experience in any given installation. The problem is that the quoted short circuitwithstand, which is seen as the indicator of a cleats suitability for a project, is only valid for acable diameter equal to or greater than the diameter of the cable used in the test.

“If the project in question is using smaller cables than those referred to in the test (andthe fault level and spacing is the same) then the force between the cables is proportionallygreater, meaning the certificate is inappropriate and the cleatswill not provide the protection they are installed to give.”

Intended to wipe out this issue, Ellis Patents new serviceprovides specifiers and contractors with the opportunity to testthe cables and cleats they intend to install in the most-extremeshort-circuit conditions likely to occur in the final installation. Aprocedure that means the tested cleats can be granted projectspecific third party certification and be installed with absoluteconfidence.

DEVELOPING A GREEN WORLD Since 2003 the Socomec group has been in the Global Compact,a United Nations scheme that aims to face up to the challengesposed by globalisation in terms of human rights, workers'conditions, environment and the struggle against corruption.More recently Socomec became a member of The Green Grid inOctober 2009 and were also amongst the first manufacturers toagree and sign-up to the Code of Conduct in 2008.

Since adhering to the schemes, the Socomec grouporganisation has had 100% control over the recycling anddisposal of the materials used in its manufacturing process andoffices. The same attitude has been adopted to after-salesmaintenance, with replaced components being disposed of inaccordance with local regulations.

Sustainability is also taken intoaccount in the production process,with continual research into theefficient use of energy and resources.

The Socomec UPS range includes anumber of products with lowenvironmental impact; two examplesof these are the Green Power UPSrange and the innovative kineticstorage system (VSS+DC).

ABB, the power and automation technologygroup, has launched SVC Light (static varcompensator) with energy storage as itslatest development within the FACTS (flexiblealternating current transmission systems)family.

The new technology combines SVC Light,with a highly scalable battery storagetechnology. The present rated power andcapacity of storage is typically in the 20 MWrange for periods of approximately 15 to 45minutes, but this technology can be scaled upto 50 MW of power for 60 minutes and more.

ABB’s SVC Light with energy storage enablesdynamic control of active as well as reactive powerin a power system, independent of each other. Fastreactive power control means that grid voltage andstability can be controlled quickly. Active power control isenabled with dynamic energy storage by levelling out powerfluctuations from intermittent generation sources such as wind andsolar energy. This technology also facilitates load support andancillary grid services such as area frequency regulation.

“This technology can play an important role when it comes tointegrating renewables, especially in weak electrical networks”said Claes Rytoft, head of technology for ABB’s Power Systemsdivision. “It can be a key enabler in the development of morereliable and smarter grids.”

SVC Light is a system connected to the grid at transmission aswell as sub-transmission and distribution levels, using state-of-the-art power semiconductors. The energy storage system is based onLi-ion batteries combined with SVC Light.

ABB is a global leader in FACTS technologies that help enhancethe security, capacity and flexibility of power transmission systems.They enable an increase in the existing transmission capacity of apower network while maintaining or improving the operating

margins necessaryfor grid stability.

SVC Light is a system that provides fast-acting reactive powercompensation in high-voltage electricity networks. Theycompensate for fluctuations in the voltage and current of anelectric grid, thereby allowing more power to flow through thenetwork while maintaining safety margins and increasing stability.

BLOWN FUSE

OUR RESIDENT GRUMPY OLD MAN, JOHN HOUSTON,THIS MONTH TURNS HIS ATTENTION TO THEGENERAL ELECTION.

I KNOW by the time this month’s diatribe hitsyour desks the election hullabaloo that has beenthis most publicly debated of popularity contestswill be done and dusted. Personally, I found thealternating public squabbling and sicklypatronisation (just in case parliament hung) veryentertaining. My fear was a large sector of JoePublic would miss the vital policy points –hencethat very nice young man Mr Clegg’s immediaterise to prominence following the first debate.

What alarmed me most about the first debatewas the very real ignorance it revealed across allthree debating candidates when it comes toenergy. One would imagine with theenvironment, perhaps for the first time, being amajor part of all three parties’ manifestos, thatone of them might have taken a little more thanfive minutes to acquaint themselves with a fewrealities.

Both Gordon Brown and David Cameron atleast acknowledged a need for nuclear power.Cameron even made the point nuclear stations

take a long

time to build. The point at issue is whoever hasbeen elected needs now to act fast – In my viewdecisions that should have been arrived at in aconsidered way two decades ago now have to betaken in haste.

Clegg’s opinion that the major investmentshould be spent on renewable is naive to thepoint of ridicule. His argument being nuclearpower costs a lot to make. He seems to havemissed the point that per kilowatt, other energygeneration is also expensive, but at least nuclearpower will give us potentially enough for apopulation set to grow to 70 million over theforeseeable future.

”BUDDY, CAN YOU SPARE AN AMP?” Will there come a time when we substitute theannual nonsense that is the Beaujolais run foranother dash across the Channel to grab a caseof EdF’s electricity. At least our colleagues atElectricitie de France (I think using the full nameemphasises where the world’s largest energy firmcomes from) make lots of power we can buy. Thisimportation brings nothing to the Britisheconomy and as I’ve mooted before, leaves us

vulnerable to the foibles of the FrenchGovernment and its economy.

David Cameron did at least statethat if nothing’s done soon, our

lights will go out. He didn’tactually venture how we willfind the finance, designexpertise or skilled workforceto fulfil a new nuclearprovision. Neither did Brown,

and Clegg didn’t even have it on his party’sagenda. As I write I don’t know who will win.What I do know is those of us who care aboutenergy had better be prepared to carry on thelobby!

GREEN POSTURINGI have derided businesses that display tokenenvironmentalism in the past. The Primeministerial candidates remained guilty on allcharges of green posturing. Asked by a memberof the studio audience in one of the live debates,what each candidate had done personally toreduce their environmental impact, the responsewas so predictable. Brown said he believed insolar power, Cameron said he didn’t do enoughbut tried not to fly too much and Clegg said heonly uses his car when he has lots of kid’s stuffto carry.

Did any of them simply state they turn lightsoff? Who ventured they might install energyefficient lighting? Who suggested they mightthrow less away unnecessarily? I could go on. Infact, I could go on and on and on.

If our newly elected leader, whoever they are,can’t even demonstrate a rudimentary knowledgeof how they might reduce their environmentalimpact (even if they don’t actually do it) it’s aworry. How can we expect incentives for theinstallation of active energy efficiency schemes(motion detection switches for example) orenergy metering for homes, or incentives to usesolar power by rebating users energy bills?

I know the Prime Minister’s now in office, butfor me the jury’s still out.

SPARKS FAILED TO FLY IN PRIME MINISTERIAL DEBATES
