ActewAGL welcomes global solar delegations

I

NTERNATIONAL delegations have kept a close eye on Australia’s solar industry boom. The Australian Solar Council claims Australians have now installed 1.3 million solar systems. As a result, the rest of the world is taking note of what Australia and ActewAGL has to offer.

Above: Taiwan delegation visit ActewAGL

A Taiwanese delegation was the first international group to visit ActewAGL last month [October] about solar. The delegation received a presentation about the penetration of PV across the ActewAGL network, a visit to the control room and an overview of our guidelines and regulations.

ActewAGL’s Customer Solutions Manager John Garvin says the reason the Taiwanese delegation visited was because our network is receptive to PV solar connection.

“The rest of Australia has had problems connecting solar, we haven’t,” he says. ”Even the Taiwanese want to know why we are different.

We have a compact, resilient and versatile network for connections above 30 kilowatts.

We do network studies and we verify that it is technically acceptable to connect solar PVs above 30 kilowatts. We do the study to see if proposals are technically compliant with our requirements.”

But Mr Garvin admits he was apprehensive at first about divulging the details on ActewAGL’s research to external groups.

“I wasn’t quite sure what they wanted or whether or not I wanted to provide them with that detailed information on our network,” he says. “But now that I’ve done it I’m thinking, it’s probably a good idea because we need to be transparent about our processes and provide useful and accurate information to our customers and engage with them.”

Mr Garvin says it made sense to encourage our customers to take on solar as an energy option.

“They want to connect and we want them to connect in accordance with our requirements,” he says. “All they want to know is what the requirements are. If we publish that then we will

form a great rapport with our customers making the connection process much easier. Customers have knowledge of what our requirements are, it’s fantastic and they really appreciate it.”

ActewAGL is in the process of managing the connection of the three largest PV facilities in Australia right now. FRV is located at Royalla, it is 20 megawatts. The second is located near Rose Cottage near the Monaro Highway and is 13 megawatts and Elementus is at Uriarra Village which is 7-10 megawatts. The first two, the 20 and 13 megawatt facilities will be the two biggest in Australia.

Mr Garvin says our success with solar is boosted by the help of detailed guidelines on the ActewAGL website that informs proponents of embedded generators on how to connect to our network. And, a new component for commercial connections (above 30kW) has secured a more reliable solar network.

“We’ve introduced a new product that we call a generator connection cubicle,” he says.

“This allows an additional degree of protection between the solar facility and our network.”

Mr Garvin says the Taiwanese visit was a success as the delegation probed ActewAGL about our operations.

“They didn’t stop asking questions,” he says.

“They said they were very pleased with the presentation and they were impressed that we were very transparent with our documents and our processes.”

Mr Garvin says he predicts it could be the start of several visits from international delegations.

“I would expect John Grimes from the Australian Solar Council will want to bring more visitors through,” he says. “We have been

recognised by the Australian Solar Council – the peak body for solar energy in Australia - for our capacity to provide a good conduit for the connection of generators to our network in a thoughtful considered way. And we get few problems compared to others; fortunately we don’t get many complaints from the public about PV connection problems. We probably only get a dozen to 20 complaints a year which is not bad from 12,000 installations. We have strategies to manage complaints and find solutions.”

Australian Solar Council Chief Executive John Grimes agreed with Mr Garvin and says he expects more international visitors will want to see ActewAGL’s solar set-up.

“In the Unites States last year they installed 40 thousand solar systems,” he says “In Australia, we’ve installed 1.3 million solar systems. And, that’s because in the US and other parts of the world they are installing large systems, businesses on farms and that sort of thing. Whereas in Australia, we put them on households.”

Mr Grimes says it is our use of solar for households that have changed the way people look at the solar industry.

“The rest of the world has a lot to learn from us about that experience,” he says “As they increase their solar penetration they’ll start to encounter all of the issues we’ve had to manage here in Australia.”

The Australian Solar Council Chief Executive believes there is genuine global interest in what we are doing here in Australia.

“We are working with the Chinese industry but also the Europeans and the Americans are they are very interested in what we’re doing,”

he says. “I’d say at least 10 countries around the world are particularly interested and I think that’s a fair representation.”

Mr Grimes says the Taiwanese delegation visit made sense because Taiwan has a very strong solar manufacturing industry.

“They are the second largest manufacturer in the world,” he says. “They are an electronics expert country. So, they were coming to Australia to find out about the Australian market, understand about regulation and solar policy.”

Mr Grimes says the delegation were keen to visit a utility while they were in Australia and ActewAGL became the logical choice.

“We recommended ActewAGL for two reasons,” Mr Grimes says. “The first is ActewAGL has a reasonably high penetration rate of PV on the network. So, they’re actually seeing it and developing ways to respond to it.

And, the second thing is ActewAGL’s response has been fairly positive. Obviously there are very strict guidelines you have to work within but there’s been a can-do attitude. So, that’s why we recommended that the delegation included ActewAGL on the visit.”

Mr Grimes believed the Taiwanese delegation had a productive visit to ActewAGL and came away with fresh perspectives.

“They were really impressed with the transparency that ActewAGL showed,” he says. “ActewAGL has developed very clear guidelines on how you connect not just small scale but large scale solar to the grid and what’s required. And, for proponents to see that right up front, to clearly understand what’s required reduces risk for everybody because it means they know what to do and for the utility then they get compliance on the network.”

While Mr Garvin says ActewAGL has had to hit the ground running to become a leader in solar as the industry took off.

“Two years ago we had practically nothing and our knowledge was near zero in this area he says. “What’s happened is the ACT Government generous feed-in-tariff has stimulated the industry here to the point where because there are only four of us in my branch, the only way I could stop the inundation of enquiries was to research and then publish relevant documents.”

Mr Garvin says to slow down the influx of enquiries, the company simply put its information online.

“All the information on how to connect your system to the network is contained on the internet,” he says.” We even have something called a grid code (our technical requirements) on which has all the National Electricity Rules chapter 5 requirements. No other utility has got that.”

Finally, Mr Garvin says ActewAGL should be very proud of the work it has put into the solar industry.

“I think what we have here is world class,” he says. “I’ve had nothing but compliments.

Our documentation is clear, it’s concise, it is transparent and we follow the process.”

Enerji Pilot Plant is a Real Clean Power Solution A

T a time when it would appear that anything green is good, for those amongst us who may be a tad cynical, Enerji presents a beacon of bright white light.

Here is a privately funded company that, as CEO, Colin Stonehouse puts it, operates in the ‘blue economy’. This is not an economic atmosphere where going green is simply the way forward because it’s fashionable, but where common sense prevails; where good business acumen and clever engineered solutions provide commercially viable and financially rewarding customer outcomes. Outcomes I might add, that really do make a difference by providing a highly practical, sustainable environmental benefit to enhance power generation.

It is a truly exciting world that lies beyond the cheap talk and green investment that often lacks a rigorous, cost effective business plan and it presents a welcome glimpse of our sustainable, energy efficient future.

In this real world Enerji has already put in place a solution that lowers power production costs and one that produces cleaner energy.

Further, the technology will be embraced because it’s a practical cost effective solution and one that can be ultimately applied across all industry sectors within our economy. It is also a technical reality that makes perfect sense.

Enerji’s Organic Rankine Cycle Model is the ultimate in re-cycling; a method that in the simplest of terms converts waste heat into usable, emission free energy and Enerji’s technology is now being trialled prior to commissioning in Western Australia.

WA’s regional electricity provider, Horizon Power should be commended for embarking on the pilot programme at their Carnarvon Power Station. Horizon Power supported Enerji with its installation of the Organic Rankine Cycle (ORC) machine to operate in the lead up to the prior to the decommissioning of the power station.

The installation of the pilot plant provides the perfect opportunity to test Enerji’s technology under the most trying on ground conditions.

The Carnarvon Power Station could be described as ‘old world’ technology in terms of electricity generation and the ORC is capable of turning old fashioned, power generation into a far more efficient and cleaner process. That alone represents a huge saving for our already fractured economy and one that in the longer term, may well have a favourable impact on reducing the cost of energy for the end user.

Above: Nathan Mathews (left) with Opcon’s Sewdish Engineers Samuel Ostman and Ingemar Sergorholm Enerji’s Organic Rankine Cycle technology is applied to the discarded heat from the exhaust produced by the power station’s generators.

The ORC acts as an extra power source in that it uses refrigerant gas to convert the 150 to 350 degree wasted heat into additional, emission free energy.

The ORC technology itself, as installed in the Carnarvon trial, is capable of generating around 700 kW of electricity which in layman’s terms would be enough to power up 988 houses and in turn improve efficiency by up to 18%.

However, the pilot plant at Carnarvon will be confined to some extent with the aim of the programme to consistently generate around 300kW from the wasted exhaust heat.

From the outset the signs have been good with the initial trial period achieving the first benchmark of 30kW. Having observed that first phase, Enerji has now modified the hot water manifolds to make them more robust under pressure. At the time of writing these are about to be installed and following a brief trial period the ORC will then convert all available heat from the generators and it is expected that a consistent 300kW output will be achieved.

Enerji Ltd is based in Western Australia and is clearly focused on lowering the cost of power production by generating emission free electricity from waste heat. Although the company’s technology is ideal for use in a power station format, when used in conjunction with generators, potentially the Organic Rankine

Above: Opcon Power Box with Cooling Tower on the left and the Control Room on the right Page 4 - Australian Power & Energy News

Cycle could be applied wherever exhaust heat exists.

When you consider that ORC is capable of producing 20% more power from an existing energy resource and lowering emissions by 15% the environmental and cost benefits become irresistible.

For instance, Enerji’s ORC technology can be used to convert exhaust gas from diesel generators, gas fired power stations, hot process water, gas compressor stations, kilns, cement and steel manufacturing processes to name just a few. So at a time when energy costs are so high and still climbing, Enerji’s role in reducing those costs and making industry more efficient has enormous appeal. Of course for government owned power generators and the mining sector the benefits are obvious.

According to CEO Colin Stonehouse, the ability of Australian industry and the mining sector to compete globally requires that spiralling energy costs must be reduced in the short term and Enerji is determined to achieve that outcome for all of its clients. Colin believes that the pilot plant is a critical test to ensure that those costs can be reduced in real terms.

“We’re very grateful to Horizon Power for allowing us to install the pilot plant. Their management and project team’s enthusiasm for the pilot programme has been tremendous and extremely helpful.

“This trial is so important because Enerji’s

focus is on the delivery of practical clean power solutions and although we are extremely confident of our technology, the machinery that applies it must be tested under rigorous field conditions.

“The pilot plant at Carnarvon allows us to thoroughly test the ORC machinery, to make modifications where necessary and to ensure that it is robust enough to consistently produce the required output wherever exhaust heat is being wasted in Australia. At this stage we are delighted with the way the pilot programme is going.”

The unit cost of every commodity produced in Australia is affected by the rising cost of electricity whether through the carbon tax, RET, solar subsidies, ‘gold plating’ or simply the cost of power generation. Therefore the ability of manufacturers to plan ahead is a difficult proposition as the goal posts continue to shift. Finding ways to reduce the cost of that energy component is paramount in terms of a company’s long term security and profitability.

The cost of electricity also affects employment opportunities and our ability to compete on the world stage.

Fortunately, Enerji through its success with the pilot programme appears to have a cost effective solution that at least will produce some certainty and leverage in the fight against rising energy costs.

The beauty of the ORC technology is that it is in essence, a simple and practical concept that can be applied to heat emitting assets wherever they exist. ORC can even capture low grade heat. This is heat that is normally wasted and emitted into the atmosphere without restraint, so environmentally this could be regarded as a highly valuable piece of technology.

Enerji is certainly leading the way in Australia with its ability to, not only create a new source of electricity, but to do it without using additional fuel or creating CO2 emissions.

It’s a welcome advance in a world where the gospel of green rhetoric tends to overshadow the invaluable efforts of people who are providing cost effective and commercially viable solutions - responses that really will result in making our planet cleaner and more efficient. This is now a world where the ‘blue economy’ prevails and those who participate deserve appreciation and reward for their worthwhile investment because it provides real and tangible benefits for all of us.

Petro Min Embrace a Waste Heat Conversion Future

T

HE team at Petro Min Engineering (PME) is excited and for good reason. The company’s contribution to Enerji’s pilot programme to turn waste heat from generators into emission free energy at Horizon Power’s Carnarvon power station has already made a difference.

In the simplest of terms, PME’s role was to design the interface between the Horizon Power facility and the Opcon Power Box which has been adapted by Enerji to incorporate and increase the efficiency of the Organic Rankine Cycle (ORC). It is this technology that converts recovered heat into new energy and, as a dramatic emission reducing process, it is the real deal. There are no emissions.

In a world where going green is often an excuse to waste taxpayer dollars on costly programmes with little tangible benefit, this particular project is a superb example of free enterprise at work. It highlights the reality that if you want to make a difference to the environment you can secure private investment when there’s a constructive and commercial outcome.

The pilot programme at Carnarvon is a great story with a happy ending not only for the environment but in terms of reducing electricity costs for end users, particularly those who operate in the energy and industrial manufacturing sector. PME’s Principal Engineer and Owner/Manager, Geoff Mitchell explains.

“Having been involved in the power sector for over 25 years, this is one of the few concepts that we see as being able to make a real contribution to energy efficiency. It reduces the environmental impact associated with traditional power production, makes money for Enerji while saving money for others and doesn’t require a subsidy or interest free loan from the tax payer’s pocket.

Here at PME we are so excited to be involved in such a project which has the capability to change the economics of remote area power stations and the industrial, commercial and domestic type loads they supply.”

PME was responsible for designing and engineering the interface at the Carnarvon power station but it all began when the company tendered for the supply of all the electrical and instrumentation equipment to facilitate the operation of the Opcon box. The company also assisted Enerji with the tender evaluations and with the review of vendor documentation.

Once the project commenced PME developed a PLC based control system to, not only interface with the Opcon Power Box internal PLC, but also to interface with the Horizon Power controls for the engines, fuel gas systems and power station management.

The control system also allows Enerji and Opcon to access the site remotely for fault finding and monitoring of the system. The aim of the installation is to ultimately generate around 500kW net from the wasted exhaust heat and the indications are extremely positive. The system is generating emission free electricity and Enerji continues to ramp up output to reach that level.

PME is one of those dynamic and very clever Australian companies that, beyond the industry, you hear little about but they are

extremely pro-active within the national power sector. The company presents an extensive range of electrical engineering and design skills that are capable of applying the cutting edge in applications related to renewable energy and enhancing or value adding for traditional methods of power generation.

PME has been extensively involved in the engineering and design of power stations, cogeneration facilities and substations in most states of Australia. A number of these installations have been applied to standalone stations which are typically for mine sites or small isolated townships in remote areas.

Others are related to grid connected power generation and cogeneration facilities in WA, NSW, Victoria and South Australia and these have mostly involved some form a cogeneration and heat recovery from the power generation engines.

Generating new electricity from wasted heat is obviously a field of endeavour that the team at PME are passionate about and it is understandable given the success of the Carnarvon pilot programme. As Geoff Mitchell says, “We see our interface role in the installation of the Enerji/Opcon Power Box as simply an extension of what we do best and the engineering and design work required are well within our capabilities. Converting waste heat

into energy is the way forward because it is now a proven and cost effective means to make electricity generation far more efficient.

The exciting challenge is to take this pilot plant and develop the capability to seamlessly interface into other power stations or process facilities with excessive amounts of waste heat and use that to generate power from the Opcon unit rather than see it wasted.

The equipment within the power box is of a proprietary nature but the electrical and controls equipment external to the box can be tailored

by PME to suit the site or a client’s specific requirements or a particular process.”

The work performed at Horizon Power’s Carnarvon power station by PME and Enerji is worthy of a much broader audience beyond the power sector. It is a significant breakthrough in reducing power sector emissions and electricity costs. It is a good news story made sweeter because it highlights the willingness of the private investment sector to get involved where realistic expectations can be met.

It is the natural way of things; a market based solution where reward motivates meaningful environmental solutions unlike the taxpayer funded green fantasies. The type that are not even remotely cost effective; contribute very little power back to the grid and will never produce the constant base load required to run our cities.

Beyond the company’s involvement in the pilot programme at Carnarvon, PME provides purpose built engineering solutions and the company’s operational reach is extensive. It covers a multitude of sectors from mining, and mineral processing to power generation and distribution. From oil and gas production to motor control and custom designed control systems, as well as fire and safety systems, fabrication and construction, manufacturing, maintenance and project management.

The onsite benefits of targeted Green Power Solutions In recent years, most Australian companies involved in construction throughout all industry sectors have adopted world best practice in terms of their approach to environmental sensitivity. The use of key phrases like ‘carbon emission reduction’ and ‘sustainable outcomes’ litter the project landscape with respect to caring for the environment.

H

OWEVER, in the area of onsite energy, the rush to embrace the cleaner and more cost effective qualities of biodiesel as a driver of temporary onsite power generation does not appear to be consistent with the overall construction trend to work cleaner and smarter.

Biodiesel Generators are the specialty of Victorian company, Green Power Solutions (GPS) and according to Managing Director Danny Williams, the environmental and cost benefits of the company’s range of biodiesel generators, which can be hired for the term of a project is an obvious winner for construction companies.

“We offer the best generators available and they are made to the highest standards in quality and the fuel that powers them is home grown.

Our expertise in bio-energy is such that we can assess the requirements of any onsite energy need and target a specific solution to suit those demands with our generators. But it is the reduction in carbon emissions and the ultimate cost savings that represent the greatest benefits for our construction clients.

Our generators are either low carbon or carbon neutral depending on the required task. Associated running costs are highly cost effective because we supply the amount of energy needed without the waste or over-capacity which is often the case when traditional generators are used.”

There are a number of examples that clearly illustrate the advantages of GPS Biodiesel Generator technology and although client confidentiality precludes mentioning the

name of the client in this particular case, it does serve to highlight those benefits and it can be verified.

In this instance the client was considering rental of a traditional 200kva generator to supply power for a project it was undertaking on a regional railway line in Victoria.

Coincidentally, GPS had just supplied smaller, 120kva biodiesel generators for a neighbouring project, which in comparison required a far greater power supply than the rail project and yet, the smaller generator had been sufficient to perform the required task.

Aware of the neighbouring railway project, GPS assessed the onsite energy needs of the construction company involved. GPS believed that a smaller generator would be sufficient to supply all the power required for the office complex onsite and also highlighted the potential savings that could be achieved without the need for a 200kva generator. The projected savings were quite dramatic and GPS anticipated that by using biodiesel they could save the client 5 litres of generator fuel per hour. This meant that over the 12 month period the construction company could save around $53,000.

Consequently, GPS provided a 120kva biodiesel generator for the site with an additional 50kva generator as a back-up and to supply power at night and on weekends.

As per its normal client service support, GPS monitored the fuel consumption onsite and remotely using ‘back to base’ monitoring.

After just two weeks it became clear that the power required on site was less than initially expected and the demand was further reduced because the company didn’t go ahead with an increase in ‘office space’.

So following the results of monitoring, GPS replaced the 120kva generator with another 50kva generator. The smaller generator operated well within its comfort zone at around 60% load and achieved a fuel consumption of 4.5 litres per hour over the 12 month period.

Ultimately all energy requirements were fulfilled by just two 50kva biodiesel generators with one of them used simply as an emergency back-up.

The fuel savings were significant to say the least, reducing the budget estimate from around 17 litres per hour to 5 litres per hour. Of course, because the construction company used the better matched and efficient biodiesel option, the improvement in fuel efficiency and the reduction in onsite carbon emissions, when compared to traditional generators, was a huge bonus and the environment was also the winner.

Danny Williams estimates that by using GPS Biodiesel Generators the company involved saved around 80,000 litres in fuel and approximately 237,000kgs of CO2 over the 12 month hire period.

Danny also believes that prior to a project it pays to look carefully at the temporary site power demands because in his experience there are often costs that do not need to be incurred.

As he says, “We can offer our clients a far more efficient package to meet their onsite power need and although on the surface the upfront rental costs might be a little more, at the end of the day, that increase in efficiency and reduced fuel costs means that the overall package is much cheaper.”

The onsite benefits of targeted Green Power Solutions

GPS Biodiesel Generators are powered by the latest Tier 111 and Tier IV engines and when fuelled by home grown biodiesel they are extremely fuel efficient. In operation they are ultra-quiet due to the use of advanced sound-absorbing technology and when running, each generator produces less than 51dB at 7 metres. The engines surpass current EPA emission standards and when fuelled by biodiesel the generators are the cleanest running generators in Australia.

Biodiesel Generators are slightly more efficient than generators fuelled by mineral diesel however, in the longer term biodiesel is a far better economic proposition and the generators operate with a negligible carbon footprint.

Of course this outcome is enhanced by the ability of GPS to assess the onsite power requirements and provide generators to specifically suit the desired load.

There are also other advantages in adopting the GPS solution. Not least is the fact that when GPS hire their generators the service includes the company’s on ground support. Once the generators are onsite, GPS monitors and tracks the power demand onsite

and remotely but perhaps more importantly GPS supplies the biodiesel to refuel the generators as required.

GPS also provides the customer with a monthly report on each generator supplied so that the client can clearly see the amount of fuel used and the average energy demand of that particular generator.

The history report also includes the carbon reduction certificate outlining the amount of CO2 emissions saved. This can be of great benefit to construction companies because they can input the information into their own NGERS reporting system and in an instant see both the cost and the environmental impact of their energy use on that project.

A further bonus is the fact that the GPS reports can assist a company that is trying to reduce its fuel and energy use. The summary provided can help to determine whether a company is meeting its onsite targets; where savings can be made and to validate its efforts in that regard.

Green Power Solutions is Australian owned and one of the world’s first dedicated renewable semi-permanent electricity producers. Prior to the company’s entry

into the world of biodiesel, the GPS team had its origin in both the motor and mining industry with an expertise in both traditional and renewable energy sources that stretches over 30 years. During that time the company accumulated a wealth of energy related industry knowledge and has since developed a specialist level of expertise in maximising the benefits of biodiesel generator technology.

GPS now leads the way in biodiesel application in Australia and has contributed to a number of major projects to reduce the construction carbon footprint including the M80 Ring Road upgrade as well as supplying the biodiesel storage and thermal control system for Hydro Tasmania’s King Island Power Station. This was done in conjunction with the company’s biofuel supplier, Pro Green Biofuels Pty Ltd. GPS is currently developing hybrid generator options that will incorporate a battery storage system as well as solar and mobile generators to further reduce onsite fuel consumption. The team is also working towards the introduction of biogas fuelled generators.

As we know in a world where ‘going green’ is the way forward, actions speak louder than words and when those actions can save money and do less harm to the environment it is a win-win for both the construction sector and the greater community. It would appear that as far as temporary onsite energy needs are concerned a biodiesel Green Power Solution is worthy of much greater consideration from the construction sector – it’s simply cleaner, cheaper and smarter.

Aerial Power Line Inspection Feature Aerial Power Line Inspections are a quicker, more cost effective and safer way of inspecting Power Utility’s Power Line Assets It’s the world’s largest connected electricity grid with a sprawling distribution system and this year more than 140,000 line kilometres of the Australian electrical network has been inspected by HAWCS. EYES LIKE HAWCS Utilities such as Energex, Ausgrid and Essential Energy work with HAWCS to determine the aerial inspection methods most suited to their organization’s individual needs.

In Queensland they need to be ready for storm season, in New South Wales and Victoria fire mitigation is a huge factor.

One goal remains the same for each network and that is to ensure safe, reliable power supply using cost effective solutions.

Aerial patrol is a pretty broad term and can range from a purely visual inspection out of an aircraft window to data capture that creates a virtual 3-dimentional LiDAR model of the network with centimeter accuracy and high resolution imagery.

Across vast transmission and distribution networks combining urban, rural and remote regions, different methods may be adopted, however, continuity of data capture and reporting across networks is also important.

More than ever asset managers are requiring complete solutions from their aerial inspection provider.

DETAILED ASSET INSPECTION AND REPORTING Vincent Van Gogh once said, “Great things are done by a series of small things put together”. Greatness may well be in the detail but the devil can be there too. So how can small but vital assets be accurately assessed from the air at a safe and quiet height?

You would need eyes like a hawk or better still imagery that allows you to detect broken ties, cracked insulators and bows or cracks in a cross arm, from the length of a football field away.

Add a highly experienced observer who also sights and captures more obvious urgent defects for immediate reporting from the field. These images are then interrogated post flight by experienced linesmen for defect analysis and reporting. All defects are coded to the Utility’s guidelines and then reported through simple excel spreadsheets for seamless integration into the Utility’s existing GIS systems.

At this resolution 99% of defects on overhead assets are accurately detected and the position of the defect is referenced to the Utility’s Pole ID. The HAWCS inspection and reporting process only takes 2 hours for every hour flown.

Utilities also require their aerial inspection to be fast, safe and quiet. Flying single-engine aircraft low and slow over a powerline is simply dangerous and outdated.

HAWCSCAN LiDAR – 500 kHz system with point density of 40 points per square metre over Transmission and Distribution lines.

Each and every point has 2cm relative and absolute accuracy.

HAWCS EC 120 with Fenestron tail rotor is the quietest helicopter in its class.

FAST Capturing each asset for post flight interrogation means the aircraft can travel at a constant speed with one HAWCS team covering more than 150 kilometres per day.

A patrol relying on an observer often requires a reduced speed for turns and hovering over the asset to assess and record the condition and position. Flying lower and slower reduces safety and increases cost.

SAFE HAWCS operates their helicopters from above 300 to 1000 feet by utilizing intelligent technology. The greater the flight height, the safer the operation. Flying higher also results in less disruption to your customers.

QUIET Quite simply, HAWCS operates the quietest helicopters in the world. HAWCS’ fleet of helicopters has the lowest noise signature of their class and these noise reduction methods have been adopted to improve environmental impacts on customers and livestock.

Asset inspection is only part of the overall picture necessary to accurately assess the condition of an overhead network. Vegetation encroachments pose a real threat to reliability and safety and hence tens of millions of dollars are invested every year by utilities Australia wide. Utilizing the HAWCS Lidar

system, HAWCSCAN, companies such as Ausgrid, Aurora, Transgrid, Powercor, Energex, NT Power and Water, Aurizon and Q-Rail have accurately and cost effectively detected vegetation defects. And that is just the beginning of the benefits of this technology to the industry worldwide.

NOT ALL LiDAR SYSTEMS ARE CREATED EQUAL It seems everyone is now talking about LiDAR – Light Detection and Ranging. The technology is grabbing the attention of Asset Managers to the CEO’s of Australia’s Utility Networks. And for good reason.

The technology is vastly improving the way assets can be managed while at the same time, paving the way for emerging technologies such as the UAV. Back in 1999 HAWCS conducted the first LiDAR survey for the construction of the Interconnector for Powerlink and Transgrid.

Over the last 14 years HAWCS has completed more than 75,000 line kilometres of LiDAR capture. HAWCS is, without exception, the most experienced LiDAR provider to the Australian electricity industry.

HAWCSCAN is a 500 khz LiDAR system which scans 500,000 pulses every second across a 300 metre swath. Travelling at 60 km/hr, HAWCSCAN delivers 40 to 50 points per square metre. This superior point density ensures nothing will be missed, no matter how dense the vegetation or how thin the conductor.

HAWCSCAN uses both GPS and Glonass satellites to provide the most accurately positioned data possible, delivering positioning information with less than 2cm variation on the ground, both relative and absolute, all from 500 feet in the air. Using both L1 and L2 carrier phases, coupled with access to all major CORS networks throughout Australia means HAWCS’ clients are assured the best results.

The model produced by these systems enables the operator to take measurements down to the centimetre, leaving nothing to chance.

ACHIEVING DETAILED ASSET INSPECTION AND LiDAR ANALYSIS FROM ONE FLIGHT With one pass, HAWCS completes detailed asset and LiDAR capture for analysis and reporting which includes: • Accurate vegetation analysis customized to the Utility’s clearance guidelines.

Page 8 - Australian Power & Energy News

This automated process eliminates the possibility of human error. Vegetation Managers are advised via excel spreadsheets/GIS on exactly how much vegetation in m3 needs to be cut per span and where the vegetation sits on the span. This information can be used to audit vegetation contractors and conduct accurate vegetation scoping of the network. Knowing where the trees are is important but knowing where the trees aren’t could save millions of dollars each year.

• Ground and water conductor clearances vital for safe operations.

• Accurate positioning of all assets in the network GIS to allow future use of technologies such as UAV’s and mobile data solutions.

• Service lines, LV, HV up to Transmission assets can be collected and assessed for the smallest of defects.

• Thermal rating with PLS CADD determining maximum sag on conductors in “virtual” scenarios.

• High resolution imagery of all assets linked to PDF reports of each feeder which highlights asset/vegetation defects and their exact position. These reports give Asset Managers the entire picture from the field to your tablet, desktop or iphone.

• Complete corridor imagery is also beneficial for species identification and access planning.

The possibilities and applications are broad and continue to grow each year with multiple departments benefiting from one aerial inspection.

HAWCS was born and raised on innovation and as the leaders in the field of powerline inspection and data capture the company is again leading the way in the field of aerial construction and powerline maintenance.

HAWCS is introducing an Australian first for the industry which will see many procedures currently performed by large ground crews, being conducted by aerial linesmen with a twin engine helicopter now operating at 35 metres safely above the powerline.

Work will commence in February 2014.

When Experience Counts HAWCS has inspected more than 750,000 line kilometres of the Australian Electricity Network over the last ten years.

Helicopter inspections for powerline maintenance

A

URORA Energy used a helicopter for the first time to carry out maintenance inspections of Aurora’s poles and wires near Railton and Sheffield, Queenstown, and also around Launceston and parts of the Tamar Valley.

Asset Manager Shaun O’Loughlin said the helicopter inspections will assist Aurora in identifying pole top defects that can affect reliability of power supply. The inspections will also allow for the measurement of vegetation clearance distances in difficult to reach terrain.

“It is extremely difficult for on ground crews to spot defects in pole top assets, so the use of a helicopter to conduct these inspections reduces the time and expense involved in manually checking these assets.”

“Local residents saw the helicopter moving relatively quickly and at low levels whilst inspecting lines. In some instances, it needed to hover over the lines to allow for more detailed assessments,” said Mr O’Loughlin.

SP AusNet strengthens electricity network for customers bushfire mitigation and electric lines clearance regulations.

“We’re running large programs across our network that will further mitigate bushfire risk and reduce electricity disruptions,” Mr Parker said.

“This includes replacing bare powerlines with insulated powerlines, animal proofing powerlines and replacing wood crossarms with steel versions, just to name a few,” he said.

SP AusNet is scheduled to meet all its regulatory requirements before the commencement of the declared bushfire season, ensuring a high level of preparedness for its network.

“Importantly, we’re engaging with our customers and the communities we work in to minimise disruptions and safely conduct our work to improve our service to customers,” he said.

The work undertaken by SP AusNet has improved supply reliability, reducing the average time its customers were without electricity for the 12 months to March by 13.7 per cent.

Left and Below: SP AusNet’s asset inspection team

SP AusNet’s asset inspection and maintenance programs are well underway on its electricity distribution network throughout eastern Victoria to provide its 650,000 customers with a safe and reliable electricitysupply.

This year, SP AusNet will devote $272 million to inspect, maintain and replace electrical assets along with $39 million to manage vegetation throughout its 49,000 kilometres of powerlines.

SP AusNet General Manager Asset Management, Alistair Parker, said that these programs underpin the company’s commitment to servicing its customers.

“Each year, SP AusNet has comprehensive Page 10- Australian Power & Energy News

asset inspection, maintenance and vegetation management programs in place to further enhance electricity reliability, quality and safety for our customers,” Mr Parker said.

“Our crews are working throughout our regional electricity network clearing 220,000 hazardous trees and branches from powerlines and inspecting 137,000 powerpoles and poletop assets.

“We also have extensive asset maintenance programs, replacing an average 550 kilometres of powerlines, 2,500 powerpoles and many more assets,” he said.

SP AusNet is also running targeted safety management and bushfire mitigation programs align to electricity safety management,

ActewAGL Maintaining it’s Aerial Electricity Network

M

AINTAINING ActewAGL’s electricity network has always been a high priority for ActewAGL and its predecessors. In 1979 the first helicopter inspection took flight courtesy of a helicopter on loan from the ACT Bushfire Council. The two three-hour flights enabled engineers to examine 90 per cent of the 130 kilometres of rural lines and complete a task that had previously taken seven days in a fourwheel drive vehicle.

ActewAGL still carries out regular helicopter inspections to conduct aerial audits of ActewAGL’s overhead powerlines to inform ActewAGL’s future maintenance program.

The patrols also provide an opportunity for ActewAGL to confirm that its vegetation management program has been implemented effectively and also form a key part of the organisation’s bushfire prevention program.

The helicopter patrol is a significant part of our bushfire prevention program. Trees and vegetation growing too close to powerlines can cause blackouts and create safety hazards such as grass fires and bushfires. Trees and vegetation can also restrict access, preventing essential maintenance from being carried out.

The patrol flies approximately 800 to 1,000 feet to identify areas where vegetation is encroaching on overhead powerlines.

Everyday our teams are out in the Canberra community fixing and maintaining our network.

But it’s also important for the community to do their bit to reduce the risk of bushfires and keep vegetation on their property well clear of electricity infrastructure.

Any damage to powerlines should be reported immediately to ActewAGL on 13 10 93.

Snowy Hydro SouthCare welcome new sponsor TransGrid

S

NOWY Hydro SouthCare CEO, Owen Finegan recently made the trek up to Sydney to meet with TransGrid Managing Director, Peter McIntyre, where Snowy Hydro SouthCare was pleased to announce a partnership with its newest sponsor.

TransGrid will contribute $35,000 to the vital helicopter service.

“This sponsorship will allow Snowy Hydro SouthCare to continue its vital work throughout the ACT and Southern NSW region,” Mr Finegan said.

Transgrid owns and manages one of the largest high-voltage transmission networks in Australia - almost 12,800 kilometres of transmission line connecting generators distributors and

major end-users in NSW and the ACT, with links to Queensland and Victoria, facilitating interstate energy trading.

“We are delighted to support such an important community cause,” said Mr McIntyre.

“TransGrid has had a key role to play in southern New South Wales over many years and this partnership continues our long history in the region.”

Mr McIntyre added that TransGrid prides itself on providing “a safe, reliable and world-class electricity supply”.

In 2012 – 2013 the Snowy Hydro SouthCare Rescue Helicopter completed 498 life-changing missions in the ACT and Southern NSW.

The use of LiDAR and PLS-CADD™ as an aerial survey technique ERIAL LiDAR is a rapid survey technique that has been employed extensively to assess electricity transmission and distribution infrastructure throughout the world. Digital 3D models are created by emitting near-infrared light from a special device mounted on a helicopter or fixed-wing aircraft. Any area that has been struck by the laser triggers a reflection that feeds back to the aircraft and is measured in terms of its exact X, Y and Z co-ordinates.

The technique allows for comprehensive data of a high resolution to be captured quickly, with typical point densities of 20 points per square metre. This means that the powerline facilities, ground surface, man-made structures and natural features can be mapped and coded, ensuring statutory electrical clearances are met for both new build infrastructure and existing infrastructure. This article will draw on three examples to discuss some of the ways LiDAR technology has been deployed to provide practical and cost-effective solutions in the transmission and distribution industry.

A

Thermal Ratings Confirmation Thermal ratings confirmation allows utilities to assess the reliability and safety of their OHL’s by identifying the maximum amount of power that can be put through a line. Firstly, the line is surveyed using LiDAR and millions of survey measurements are collected. These measurements are then

Page 12 - Australian Power & Energy News

imported into PLS-CADD™ software and used to form a ‘point cloud’ for the conductors, structures and surrounding features, including the ground surface, vegetation, buildings and undercrossings. These features are then coded so the computer can identify each object and assess the required clearance from the conductors. An engineering model of the overhead line is developed for the conductors and structures at the as-surveyed temperature, calculated using both ground-based weather data and line load data supplied by the utility.

This means that the conductors can be sagged to their maximum operating temperature and any reliability or safety issues caused by objects that are too close to the line can be determined. This includes both phase-tophase and undercrossing clearances. These are reported along with the maximum thermal rating of the line.

Thermal up-rating Once the maximum operating temperature of a line has been determined, opportunities to increase the thermal rating can be explored.

For the majority of cases, this will involve using the PLS-CADD™ models to understand and alleviate thermal constraints to up-rating that have been encountered. Using engineering models, recommendations can then be made for the most pragmatic and cost effective solution to increase electrical load transfer

capacity, whether that be through suspension clamp offsets, increasing structure height or reconductoring.

If a utility chooses to re-conductor a line, full structural models can be developed to simulate loading on the structures and recommendations made for any additional bracing that may be required. Network Mapping recently completed a project for Western Power by deploying a LiDAR system on a helicopter supplied by Aeropower Pty Ltd.

Vegetation management and bushfire prevention LiDAR technology can provide the backbone to any vegetation management and bushfire prevention program by delivering the worst spatial and vertical extents of any vegetation infringements for a conductor within a pre-defined radius. Checks are made at the maximum thermal rating, or a combination of any loading and weather scenarios to pinpoint vegetation that requires attention. The data is processed in PLS-CADD™ where the conductors are graphically modelled to their maximum sag and a danger tree analysis is run to the utility’s specific requirements. This data can then be taken forward as part of a bushfire prevention program and used to produce a detailed schedule of vegetation encroachments that requires inspection on the ground, and application of chemical or mechanical

Overhead/Underground Pole Line Hardware Equipment Feature

Hy-Haul Takes the Hard Work out of Cable Pushing

Above: Hy-Haul’s HW116 generation 3 Cable Pusher and right with diesel power pack option

M

ANUFACTURING cable pushers for the power sector is nothing new for Hy-Haul but the company’s latest model, the HW116 Cable Pusher represents a generational leap in design and development.

Safety and operational efficiency were obviously two priorities in the design of the HW116 and the result is a machine that removes any need for a manual, hands-on approach. The HW116 can be controlled and operated by electric pendant or via radio remote control.

Power options include a diesel power pack, 3 phase electric connection or it can be hooked up to an excavator or similar.

Already Hy-Haul has chalked up numerous sales of its new cable pusher with Bechtel being one of its first HW116 customers using it for the Gladstone LNG project in Queensland. Other clients included Jemena/Zinfra, SP Ausnet as well as a number of international customers.

Feedback from those clients suggests that the HW116 is far superior to any equivalent product currently available.

One of the advantages is that Hy-Haul can customize the HW116 to suit the particular task at hand and the variety of front line environmental challenges that might be faced in any given project. Both the power source and the variety of cable requirements including pushing 3 cables at one time can be accommodated by the HW116.

The HW116 has numerous safety features and includes a vertical stand which allows the cable pusher to be lifted off the ground. This feature is particularly beneficial when working in a tunnel where cables need to be kept off the ground.

It also has a supporting frame that can be used to bolt the pusher to a wall when used vertically in an elevator shaft or similar and can be bolted down when used in a trench.

The HW116 has a Ramp Guiding Edge which is a unique advantage as it overcomes tracking problems traditionally associated with other cable pushers.

The guide ensures that the grip pads ‘kiss’ the cable at all times and apart from protecting the pads the guiding edge keeps the HW116 on track. Adjustable guiding rollers also allow greater cable ‘feed’ accuracy and a consistent, smooth ‘flow’ of the cable.

The HW116 standard cable diameter is 40mm to 150 mm but it can be customised to suit individual requirements such as a 200mm cable diameter.

Page 14 - Australian Power & Energy News

The hydraulic motors on the HW116 are connected mechanically and push rather than pull. Because the motors work independently of each other they provide greater protection for the pads, track and the cable itself.

When the tracks are closed mechanical grip is achieved by small amounts of pressure being exerted on the cable across a wide area rather than high pressure on a specific area of the cable.

This feature protects and secures the cable as it moves through the machine.

For further cable protection the HW116 also incorporates an adjustable pressure valve and a pressure gauge so selections can be made to suit the nature of the job.

The machine can be controlled accurately by remote control either by radio or an electric pendant up to speeds of 20 metres per minute.

Both forward and reverse movement and speed in both directions can be remotely controlled.

The HW116 has many other important features but overall its design indicates that the team at Hy-Haul understands the particular challenges faced by operators when laying cable, whether above ground or under the ground. The Australian owned company has produced a high quality, robust cable pusher which is much safer, extremely efficient and with a capacity to endure the most challenging of environments.

Hy-Haul has been manufacturing cable hauling machinery in Australia for the power and mining sectors since 1985 and the new HW116 cable pusher is yet another addition to the company’s broad range of products.

The features included in the HW116 and more importantly, its ability to perform consistently in the front line reflects that wealth of experience accumulated over the years.

Innovations for Working in Remote Areas

T

HE Australian electricity distribution industry is often a challenging area to work in. When Australia’s Electricity network was in it’s infancy, linesman and engineers established electric lines through some of Australia’s harshest landscape to service customers in remote areas of the continent. Because the structures installed by these pioneers of the electricity industry were designed and built to withstand the test of time, the operators of Australia’s modern electricity network have inherited these aging assets and are tasked with the responsibility of maintenance and replacement of various components of the network in difficult to reach locations where it is often impossible to bring in heavy machinery for mechanical assistance.

The maintenance and replacement pole. However, as is the case with hard process coupled with the pressures on working electric utility companies, all of network operators to reduce operational their time is taken up constructing and costs and improve operator safety means maintaining their electricity network. line workers, engineers and operational To bring the concept to fruition, SA Power support staff are constantly looking for new networks contacted Thew and McCann and and innovative ways of doing their jobs. handed over the design so that they could This process of continuous improvement carry the project to completion.

Scenario 1 - Live crossarm

replacment on non-circular structures The South Australian electricity network has a unique limitation in that it is in a location with little local hardwood supplies, and very hungry termites. As necessity is the mother of invention, this limitation gave birth to a South Australian innovation known as the “Stobie” Pole.

The Stobie pole is an excellent example of the above mentioned structures which are designed to withstand the test of time, however its unusual cross section of concrete and H section steel beams mean that standard crossarm replacement tools will not safely attatch to a Stobie pole.

Undeterred by the hurdles, the operator of the South Australian network, SA Power Networks was determined to find a safe solution for live replacment of failed crossarms on Stobie poles. The engineers, operational support, and field staff at SA Power networks put their heads together and came up with a prototype design for a bracket which facilitates the attachment of a TMAC temporary crossarm to a Stobie

Above: TMac cranelift temporary crossarm in use on Stobie Pole in Belair, SA Page 16- Australian Power & Energy News

Above: The TMac unilift assembly positioned on a crossarm

Scenario 2 - Safely Lifting Conductors and Equipment when Working Aloft The terrain covered by the rural New South Wales electricity network is wide and varied. Most of its network is characterized by long feeders, and long spans. Much of the rural network is comprised of single wire earth return (SWER) feeders which can run for hundreds of kilometers.

When Mother Nature pays the network a visit, often repair crews are left with the daunting task of restoring fallen feeders to their rightful place, which unfortunately is a tiny groove on top of an insulator which is mounted right at the tip of a bare pole.

In emergency situations, repair crews are often unable to get heavy lifting equipment in to lift the conductor back to the pole top, so lifting by hand is the only option.

Recognising the risk of manual handling (Continued on next page)

Innovations for Working in Remote Areas (Continued from previous page)

injuries arising from such a demanding task, Essential Energy staff contacted Thew and McCann requesting a solution to the problems associated with hoisting conductors to the tip of a bare pole. Thew and McCann subsequently developed the UNI-LIFT, a small, lightweight jib hoist which allows the groundperson to hoist conductors and equipment above the pole top.

At first glance the UNI-LIFT appears to be a rather simplistic design, but closer examination of its specifications and construction reveal something else. Firstly the UNI-LIFT is required to support a lift of 125kG, this doesn’t sound like much until you examine the requirements in detail.

For the jib to support a 125kG lift, it needs to support 125kG of equipment PLUS 125kG of downward force applied to the lift by the ground team, possibly using “double blocked” rollers to gain enough advantage to safely complete the lift. This is a total of 250kG force applied to the tip of the UNI-LIFT. Added to the difficulty of fulfilling this requirement is compliance with Australian safety standards for lifting equipment which require that devices providing mechanical advantage to the operator be capable of withstanding 200% of their rated load without failure!

The team at Thew and McCann strapped on their thinking caps and got to work.

This heavy duty lifting device needed to be able to support 500kG at its extremity, and still be able to be safely lifted and fixed to a pole top by a single person. The solution was found in the construction methods used on modern aircraft. The Thew and McCann team designed a jib which was made of lightweight aluminium alloy, reinforced internally with a wound glass reinforced polymer tube. This sandwich style construction results in an exceptionally strong and lightweight superstructure.

Testing in an independent NATA accredited laboratory confirmed the suitability of this design and now the UNILIFT is available for general use

Scenario 3: Providing a Safe Platform Surface for Linesmen Working in Unfavorable Conditions The TMAC Universal Pole Platform (UPP) was designed to provide a safe, ergonomic working platform for line workers aloft on wood, steel and concrete poles. It was originally developed by Thew and McCann in conjunction with Integral Energy (Now known as Endeavour Energy) which has an electricity network comprising of mainly urban and suburban areas. Such was the popularity of the UPP that it was quickly adopted by different organizations around Australia. Recently, users in rural areas have noted that unfavorable weather conditions, such as heavy rain causing mud to be tracked onto the platform deck can make it more difficult to obtain a secure footing. Embodying the company’s commitment to constant improvement, the development team embarked on a project to develop a more slip resistant surface for pole platforms.

The team investigated several methods of surface preparation and after many testing programs developed a method for permanently bonding a traditional rubber non slip mat to the polyurethane platform during the manufacturing process.

This new process is the fusion of old and new technologies, which offer the superior slip resistance of traditional rubber, along with the longevity of modern polymers. This new deck design is currently undergoing quality and durability assessment and is scheduled for general release in 2014.

For more information on the technologies presented above, Please contact Dan Margetts – Sales Manager or Mark Pointing – Technical Manager on (07) 3826 6000.

Overhead/Underground Pole Line Hardware Equipment Feature Western Power’s record wood pole blitz in Kalamunda

W

ESTERN Power is targeting the Shire of Kalamunda as part of a record wood pole replacement program aimed at improving the safety and reliability of the network in the area.

More than 900 poles will be replaced over the coming months, as part of the largest single network upgrade in the area since it was constructed.

Western Power crews have already replaced more than 750 wood poles, including the upgrade or replacement of six kilometres of powerlines.

“This operation has been months in the planning and involved bringing together a massive workforce in response to community concerns about a higher than average number of outages” said Western Power CEO Paul Italiano.

Western Power will aim to complete most of the remaining work under ‘live’ conditions, resulting in minimal outages for customers in the coming weeks.

“We are always conscious of the inconvenience to customers while we carry out essential network maintenance.

Wherever possible we try to carry out work on the network under live conditions.

“We would like to thank the Kalamunda community for its ongoing understanding and patience during this large scale

operation” said Mr Italiano.

Over the past 24 months, Kalamunda residents have experienced a higher number of outages than the Perth Metro average. It is expected that over time the upgraded network in the area will result in improved reliability as well as a reduced bushfire risk.

“This approach to maintenance will ensure our core values of safety and reliability are delivered to the highest risk areas of the state, in a timely and efficient manner.” said Mr Italiano.

Members of the community showed strong support for the project, with some residents volunteering to assist with traffic management and others providing access to their properties for Western Power crews.

Typical Arc Flash injuries

What is Arc Flash?

An Arc Flash or arc fault happens when electric current ows through air gaps between conductors, causing a short circuit.

When does it occur?

Arc Flashes often occur when racking in a breaker, performing switching, due to insulation failure, or accidents caused by touching a test probe to the wrong surface or slipped (non-insulated) tools.

Hand with Arc Flash Burns

What makes up an Arc Flash?

In its most basic form, an arc is made up of four elements; thermal energy (heat), acoustical energy (sound), pressure wave and debris.

Each of these elements can cause serious injury or death to a person.

The dangerous part The most dangerous part of an Arc Flash incident is the fact that it creates temperatures high enough to burn skin, but also ignite non Arc rated clothing. Burns due to burning clothing are the most serious, involve large percentages of the body and are more often than not, fatal.

Overhead/Underground Pole Line Hardware Equipment Feature

SP AusNet ‘self-healing’ fault technology

M

ORE than 90 per cent of SP AusNet’s 652,000 electricity distribution customers now have ‘selfhealing’ technology on their powerlines designed to automatically restore power supply within 60 seconds of a nearby fault.

SP AusNet developed the Distribution Feeder Automation (DFA) technology as part of its commitment to provide customers with a safe and reliable supply of electricity.

SP AusNet’s General Manager Asset Management, Mr Alistair Parker, said the breakthrough technology has significantly improved reliability for customers since introduced in 2008.

“Previously, when a fault occurred, such as a tree falling over a powerline, the electricity supply would be disrupted along a large part of the powerline, affecting many customers,” Mr Parker said.

“Now, the DFA technology instantly pinpoints the faulty section of the powerline and automatically restores power to the majority of impacted customers by operating remote-controlled switches to safely re-route the electricity supply around the fault.

“The process is completed usually under a minute, radically reducing the unnecessary time customers were without power while crews physically patrolled the powerline to find and fix the fault,” he said The DFA’s ability to automatically switch the network has significantly reduced the company’s overall average unplanned minutes off supply per customer.

During a recent storm event, the DFA technology automatically restored electricity supply to 11,542 customers in less than a minute, effectively halving the number of customers that were without power until powerline damage from fallen trees was repaired.

Mr Parker said in addition to detecting faults and redirecting power supply via the DFA, the company’s intelligent devices installed throughout the poles and wires network are capable of transmitting key operational data and being remotely managed.

“SP AusNet’s electricity network now has leading edge capabilities for remote communication, monitoring and network analysis,” Mr Parker said.

“As such, our network is in effect talking to us, proving operation data from our terminal stations right through to our powerlines in

Above: SP AusNet’s control room and systems used to monitor the DFA technology regional areas and connections to suburban customers’ homes.

“Sourcing this information, now made even more robust with the installation of smart meters, allows us to make more accurate and

timely decisions on maintenance programs and identify safety issues.

“This modernisation is making significant advances to provide our customers with superior network and energy solutions,” he said.

Western Power powers up new transmission line

W

ESTERN Power’s Mid-West Energy Project (MWEP) powered forward recently with the energising of the first section of the new transmission line.

The transmission line connects Regans Ford and Cataby and is the first of three sections to be completed on the $443 million project.

“Energising the transmission line along this thirty kilometre stretch of land is a key milestone for the project,” Project Manager Ian Anderson said.

“We are now able to progress the next two phases of the project, which will increase the amount of power we can transport along the Mid-West corridor” he added.

The Karara Iron Ore Mine venture in the MidWest is underpinning the need for this critical infrastructure, with capacity for further mine expansion in the future. Additionally, the MidWest corridor has exceptional wind resources, which can be harnessed for renewable wind generation projects.”

“This is a significant infrastructure project for the people of Western Australia. It will help power the State’s growth for decades to come while adding security of supply for customers in the Mid-West region,” Mr Anderson said.

The new transmission line is supported by

Page 22- Australian Power & Energy News

steel lattice towers, which replaced the old wooden cricket wicket line that was built 40 years ago.

When completed, the new transmission line will allow a significant increase (between 5 and 10 fold) in the capacity of the old power line that connected the Mid-West to Perth.

Construction is advancing at pace with the next phase of the line already underway between Cataby and Eneabba. Works are also commencing between Regans Ford and Pinjar.

“Right now we are working on tower foundations just north of Pinjar, which lays the groundwork for our crews to assemble the steel towers in place. It’s the most efficient way to build these towers that soar 67 meters overhead.”

Western Power began construction on the MWEP project in late 2012 and the project is expected to be completed in June 2014.

MWEP Statistics: • 388 towers • 9,800 tonnes of steel • 1.16 million bolts • 2,900 kilometres of powerlines • 300 strong workforce

Affordable Portable Power Quality Analysers by Sonel Portable Power Quality Analysers have escalated in price over the years as their capabilities have increased. For many users the full capabilities are seldom if ever used, meaning you are paying a premium price and may not receiving value for money.

Sophisticated versus Value for Money It can be argued that a comprehensive analyser is equally capable of more mundane analysis, which is true and it is more economical for the manufacturer to make one model to suit all applications which is equally true, provided the basic user perceives it to be value for money.

The expectation that sophisticated analysers would allow anyone to monitor and interpret the complexities of power quality y has proved optimistic. Few users fully appreciate ciate harmonic analysis and even less understand flicker.

With many power quality analysers pushing the $10k barrier, price objections by less demanding users are becoming more frequent.

What Users Require Customer feedback has confirmed the following requirements account for around 90% of applications: • Loading – current demand on transformers and switchboards • Voltage & current phase balance • Maximums & minimums of daily current and voltage per phase • Voltage sags & surges • Power factor • Voltage stability against load • Energy consumption The options are to design both a basic low cost analyser and a sophisticated more expensive analyser or find a way of manufacturing a full function analyser at a price that is acceptable for less demanding applications.

Two new models – advanced features – affordable price Sonel have achieved what is almost impossible with two new analysers specially customised for Australia resulting from a close co-operation between Sonel and Pacific Test Equipment. Both models have full power quality capabilities, the main difference being the sophistication of communications.

New model prices start at around 30% of the competition and the model with colour LCD and latest generation communications for around 20% less than the nearest present day competitor!

In summary, if you don’t need remote communications or see real-time measurements on a LCD as opposed to your PC, you can save a sizeable amount of money!

The Australian versions of the PQM-700 and PQM-702 will soon be released in Australia.

Both models share the following common features: • Compact design – will fit inside most service cabinets and switchboards • Weatherproof to IP65 • Supplied with pole straps and DIN rail mount • Current measurement with 4 x flexible Rogowski coils • Optional 10 Amp current probes for CT secondary applications • Voltage leads in Australian colours with interchangeable large insulated clips for overhead and small clips for switchboard installations

Making the Best of Testing Times

I

F there were gold medals awarded to those who operate with distinction in the world of testing and calibration and in particular, for those who are determined to be the best of the best, then Mobile Test ‘n Cal would be right up there.

This award winning and highly accredited mobile testing company based in Queensland takes what it does very seriously.

Mobile Test ‘n’ Cal’s fleet of service vans are state of the art and fully equipped to produce up to 210,000 volts safely which allow operators to test any piece of critical safety equipment on site. It includes anything from LV gloves rated at 500V to large elevated work platforms as well as cherry pickers or bucket trucks which may require testing up to 207kV. But what really separates Mobile Test ‘n Cal from their competitors is the level of training and support provided for their field personnel and it’s an ongoing disciplined process.

The company even employs a highly qualified Technical Manager whose sole duty is to train field staff and provide instant advice whenever required by their mobile technicians. The high level training provided encompasses not just a full in-house intensive training package, but also includes ongoing tuition on the latest electrical instruments and safety equipment as well as ‘best practice’ work processes. Importantly, training includes not just theory but practical front line application covering everything that is learnt in the classroom.

According to General Manager, Alex Loew the company’s philosophy is simple; “Our aim is to be the very best at what we do whenever and wherever we’re required so our whole training programme must be of the highest standard. Not only do our staff deserve that support but so do our clients. This is a safety issue and our clients need to know that when we test or calibrate their equipment that it will fulfil the task required with the utmost accuracy and their employees are never at risk due to faulty electrical equipment.”

Apart from the Electrical Safety Regulation 2002 which states that, “it is mandatory for an Employer or Self Employed Person in the electrical industry to ensure the suitability of any safety equipment, test equipment or test instruments every 6 months”, it’s also a question of efficiency in the delivery of electrical energy.

Operators in the electrical industry cannot afford to lose time or efficiency due to faulty equipment and whether it’s the accuracy and safety of equipment or concern for the potential loss of working hours, downtime can be costly. Mobile Test ‘n Cal not only makes it easy for clients to abide by regulations by providing an ‘onsite’ service but the onsite delivery of its services minimises or eliminates any down time due to service requirements.

Mobile Test ‘n Cal also provides records of all testing and calibration for their clients to ensure that regulatory standards are always maintained and can be proven.

Bear in mind that as per the Electrical Safety Regulation 2002; “Test Results for the Test Instruments must be kept for a minimum of 5 years. Failure to comply can result in a maximum of 40 Penalty Points.”

These regulations and others cover the electrical industry and for the most part, are about maintaining safety and efficient workplace standards as well as ensuring a consistent, standardised output of electrical supply and associated equipment. It’s in maintaining those mandatory standards and equipment safety that Mobile Test ‘n’ Cal provides the complete service.

Tester Page 24 - Australian Power & Energy News

Mobile Test ‘n Cal is the preferred choice throughout the energy sector across South East Queensland, particularly testing and calibrating safety equipment and instruments at power stations. Elevated Work Platforms (EWP) are another speciality and Mobile Test ‘n Cal EWP services are always in demand.

Recently, the company also opened a new branch in Townsville to cater for demand for its services in Queensland’s northern region and through franchise acquisition is continually spreading its operational coverage throughout Australia. Mobile Test ‘n’ Cal already provide the complete service package in Papua New Guinea through its branch office in Port Moresby.

Mobile Test ‘n’ Cal’s approach to calibration is based on comparing an instrument designed to measure with the required test standard. However, the test equipment they use is NATA Traceable and provides the highest levels of accuracy in the industry.

The calibration process itself produces detailed reports for clients on the tested equipment as per the specifications of that particular piece of equipment. In effect the comprehensive testing and calibration process reveals both the current state of the device and reveals whether there is any potential for faults to occur.

Recently, Mobile Test ‘n Cal increased its range of services with the addition of Infrared Temperature Gun and Thermal Imaging Camera calibration.

High Voltage testing is a particular benefit for Mobile Test ‘n ‘ Cal clients because apart from the mobile service minimising downtime, the company’s vans are equipped to test any piece of safety equipment such as gloves, mats and hotsticks.

The ability to test insulation materials is a huge safety issue and the company’s mobile technicians can ensure that any insulation material is performing to the specified standards incorporated within its design.

Mobile Test ‘n’ Cal are qualified to meet compliance and mandatory requirements for the complete range of electrical measuring devices and safety equipment including; Insulated Gloves; Insulated Mats; Rescue Kits; Hot Sticks; Elevated Working Platforms; Tiger Tails; RCD Testers; Insulation Testers; Multimeters; Clamp meters; PAT Testers; Multifunction Testers and Voltage Testers and much more.

As for gold medals? Not quite but Mobile Test ‘n Cal does win its share of awards including a recent 2013 NECA Excellence Award for the company’s contribution to Boom Sherrin’s fleet of Elevated Working Platform trucks.

The 78 strong rental fleet had to be tested for post-rebuild acceptance in a process expected to take around 12 months.

Mobile Test ‘n Cal‘s first challenge was to secure the right testing machinery and this meant sourcing High Voltage testing apparatus capable of testing up to 300kV from overseas. This was achieved very quickly and as soon as each rebuild was completed Mobile Test ‘n Cal conducted the appropriate tests so that each truck would be available for rental as soon as possible. The company also rectified certain problems that were discovered following the rebuild to ensure that each EWP presented a safe and functional working environment.

Executive Director of National Electrical and Communications Association (NECA) in Queensland, Mr Mick Logan, said in presenting the award to Mobile Test ‘n Cal and other winners; “The electrical and communications contracting firms that have won an award today are simply outstanding for what they have achieved during each project.”

According to Mr Logan, the winning companies were chosen because of their commitment to excellence, significant engineering achievements and most importantly their ability to integrate many different technologies into the one project.

In itself the award, like many others the company has received, highlights the dedication of Mobile Test ‘n Cal to maintain the highest standards of service. Perhaps it’s that consistency in delivering a gold medal performance every time is why the company will continue to win new business and attract new franchises across the country.
