The increasing demand for energy and the need to cut carbon emissions has rapidly accelerated the growth of energy-efficiency technologies and programs. In this article, Geoff Stapleton, Managing Director, Global Sustainable Energy Solutions (GSES), and Susan Neill, Engineering Director, GSES, provide insights on the growth of the renewable energy sector and how electrical contractors could turbocharge their business by undertaking training in energy efficiency and solar power.

R

enewable Energy has been around for thousands of years but has not always been described as ‘renewable energy’. It was only a few hundred years ago that trade between continents was by sailing boats (wind power) and civilisation has always used the sun to dry materials and foods such as crops, mud bricks and clothes. It is only with the use of fossil fuels over the last few hundred years and the electrification of the world that the aim for sustainability has been linked to energy and therefore the terms ‘renewable’ and ‘sustainable’ energy were born. However, the growth in renewable energy over the last decade has seen a huge demand for electrical contractors to expand their skills to suit this market and to expand their businesses.

Within renewable energy there are many different technologies: wind energy, solar thermal energy and solar electric energy known as photovoltaics or PV. Although some electrical mechanics would be involved in the wind farm industry and possibly the solar thermal power industry, it is the PV industry which has seen the demand for electrical contractors in recent years. The growth in this market has been substantial. At the end of 2006, after six years of the Photovoltaic Rebate Program (PVRP), only 3390 grid-connected solar systems had been installed. However, in only another five years, at the end of 2011, this figure had grown to 634,628.

Some may see solar grid-connect systems as an ‘overnight’ success, but the solar industry is not new. Solar modules have

been in use for the ‘off-grid’ or standalone power market worldwide since the 1960s and within Australia as a market product since the early to mid-1970s. In July, the annual ATRAA conference will be held in Sydney. ATRAA was held as the original conference for those retailers/ installers involved with alternative energy, but the first ATRAA meeting was held in the 1970s and it then became an annual conference in the 1980s. During the last century, the solar electric industry was involved in supplying systems only to those households not connected to the grid. This was a small, dispersed and very difficult market to work in. Many of these systems used ELV battery banks and the installation on the DC side did not require an electrician. Electricians were only required for the connection from the inverter (device that converted DC to AC) to the switchboard of the house.

By the late 1990s, the first grid-connected PV systems were installed mainly as demonstration systems or by the solar enthusiast. This situation changed in 2000 with the commencement of the Photovoltaic Rebate Program (PVRP), which resulted from a deal between the Democrats and the Liberal government for the introduction of GST. This program encouraged the installations of grid-connect PV systems as well as supplying financial support to those not connected to the grid. However, in the first five to six years, the majority of the rebates were still being used for off-grid or stand-alone power systems (SAPS), as shown in Figure 1. This shows the breakdown of grid-connect versus SAPS systems by state from the start of the PVRP until May 2005. This shows

that more SAPS were installed during the first few years of the PVRP than grid-connect systems. The PVRP then became the solar home and community program (SHCP) and continued until the last application was accepted in June 2009.

Table 1 shows the installed grid-connect systems by year since 2000; Figure 2 shows the total installed capacity in kW by month and type for the life of the PVRP/SHCP. These tables and graphs all show the rapid growth from mid2007, but it also shows how rapidly the number of systems installed increased following the cessation of the SHCP program in June 2009.

During the life of the SHCP, the first growth catalyst came from the doubling of the rebate from $4000 per kW to $8000 per kW during the last Howard government’s budget in May 2007. Over the last few years of the rebate, the price of solar modules started to decrease, not because of Australia’s growth but because of the industry growth worldwide and the rapid increase in production capacity, particularly in China in recent years. At the end of this rebate, the Renewable Energy Certificates (REC) scheme (as part of the Renewable Energy Target) had started and a multiplier had been applied to the certificate value payable for solar systems. This helped maintain the growth, but the overall continuous growth was stimulated by the variety of feed-in tariff programs introduced by the states. Table 2 provides a summary of the various programs that are current and have existed over the recent years.

But what has all this meant to the average electrical contractor? Where have the system installers come from? What training was provided?

All Solar PV systems eligible to receive the rebate under the PVRP and SHCP or systems now claiming Small Technology Cer-

tificates (STCs) through the REC program had to be designed by an “accredited” designer and installed by an “accredited” installer. This accreditation was initially administered by the Solar Energy Industry Association, which has now evolved over the years into the Clean Energy Council. The accreditation program resulted from discussions held at the 1992 ATRAA conference. After this conference, the recently revamped Solar Energy Industry Association (SEIA) was successful in obtaining funding from the federal government to develop a training program and accreditation program for the solar energy industry. The program was launched and the first training course was conducted after the 1993 ATRAA program. SEIA also played a leading role in the development of industry standards to the extent that Australia is one of the leading countries having many renewable energy-related standards developed since the mid-1990s.

From the late 1990s, the industry association worked closely with the Electrotechnology Industry Training advisory Body, now known as EE-OZ, to have renewable energy courses within the national Training Package. This led to the association no longer offering its own courses, but requiring all those who wished to be accredited to undertake specified training courses (Units of Competence) through registered training organisations (RTOs).

The rapid growth in the number of systems being installed over the last five years has also resulted in a rapid growth in training courses and training providers. This growth is shown in the number of accredited electricians. Figure 3 shows how the number of accredited installers has grown from 327 in 2006 to 4273 in September 2011.

There are some who argue that the accreditation and the associated training is not required. However, with the growth of the industry, there have been problems and some of these have been discussed

Sometimes it’s more than simply turning the lights off

Schneider Electric’s range of meters shows you how you use your energy, so you can reduce consumption.

With rising power costs and compliance, energy efficiency is high on the agenda for every business. But before effective change can be made, it’s essential to understand where, when and how your energy is being consumed.

Schneider Electric’s advanced range of power meters makes it easy to measure energy use, and identify potential savings and dysfunctions. They also enable sub-metering in multi-tenant environments and loads on one or three-phase supplies.

(Available now)

It then becomes a whole lot easier to plan a strategy to lower energy consumption, achieve targets and comply with all relevant legislation.

PM5350 is just one of the meters from Schneider Electric’s comprehensive range of energy monitoring devices.

in other forums over recent years. For any industry growing so rapidly, there will be unforeseen issues, but it is important that quality training is available for the electricians to learn the new skills required for this growing industry.

As of March 2012, there were over 670,000 systems installed. This now gives rise to another issue - the need for ‘awareness raising’ of these systems. Electricians that have not been trained on solar systems need to be aware of what to do when working on a house where one is installed. Other tradespeople and emergency workers also need to be made aware of these systems. EE-Oz has recently formed a committee to oversee the development of training resources to meet these requirements.

8 ELECTRICAL SOLUTIONS - JULY/AUGUST 2012

The cost of solar systems has dropped substantially over the last few years such that some now argue that based on 20-year life cycle costs the technology has almost reached grid parity. Although the industry has grown rapidly over the last five years, the last 12 months has seen many of the drivers stopped. The many state-based FITs have been removed (no real FIT for NSW) or decreased substantially (Queensland’s announced in June 2012 a decrease from 44 c/kWh to 8 c/kWh). This has led to many leaving the industry, some sources quoting leaving in their thousands. FITs are the main drivers at the moment. People who buy systems want to get paid for the energy they provide to the grid. Ideally they would like to be paid the same price for the energy they provide to the grid as the price they pay for the energy they use from the grid. This would be a substantial driver and is the element required for the industry to maintain growth.

On 1 July the carbon tax was introduced. This new tax keeps ‘green issues’ and ‘clean energy’ in the eyes of the consumer, but in itself, it will not have a direct benefit for the PV industry similar to what the previously described market drivers have had. Commercial PV systems will continue to be installed because these installations will typically see all the energy generated consumed on site and therefore their power bills will be reduced.

So the ‘boom’ for the solar industry is possibly over, but the industry is here to stay. The price has reduced from the $10 to $15 per watt installed of 10 years ago to $2 to $3 per watt installed (and sometimes even less). Businesses and the general public like having their own solar systems which reduce their power bills.

Building a storage environment for super-efficiency The growth of stored data is being driven by a need to leverage new data sources (web-based social media, for example) to create new business opportunities. The current ways of managing data in this environment are not sustainable, however, so IT administrators must therefore respond by becoming more efficient.

Leaky feeder cable The T-Rad-600-FR-MSHA 1/2″ leaky feeder cable, from Times Microwave Systems, is a low-loss, flexible, non-kinking RF leaky feeder transmission line cable that provides radio frequency coverage in enclosed or underground areas, where single point source antennas are not practical. It is suitable for various interior communication coverage solutions, including 2-way communications and RFID (radio frequency identification device) for mine safety systems.

Marked with an MSHA (Mining, Safety & Health Administration) qualification reference number, it is suitable for use in mining applications where MSHA approvals are required.

The T-Rad-600 leaky feeder cable is run throughout the mining tunnels and allows a controlled amount of signal to leak into the surrounding environment. This enables the cable to receive and transmit, where radiofrequency coverage is required. T-Rad cable can be run into splitters, providing a means to run leaky feeder cable into shadowed

Planetary gearheads for DC motors maxon motor’s GP 26 A planetary gearheads for DC motors offer the same modularity, precision and power as previous generations, but with higher permissible loads.

The power increase is the result of the integration of a robust, preloaded ball bearing, optimised gearhead geometry, high permissible motor speed and the optimised dimensions of the output shaft.

The gearheads have been released to close the gap between 22 and 32 diameters in the range of power-optimised gearheads.

Part of the maxon motor modular system, the gearhead is available in one- to threestage versions, with a total of nine different reduction ratios, from 5.2:1 up to 236:1. The maximum continuous torque of the one-stage version is 0.75 Nm and of the three-stage version is 4.5 Nm. Short-term torques are 1.1 Nm and 6.2 Nm respectively. Thanks to preloaded ball bearings, the tempered, rust-free output shaft has no axial play.

The GP 26 A gearhead can be combined with five different DC motor types within the maxon motor modular system to form powerful drive units, eg, combining with dynamic maxon motors and sensor systems (encoders). For the control functions, various 1- and 4-quadrant controllers, as well as positioning controllers, are available.

The GP 26 A gearhead is suitable for applications such as engineered robotic devices, battery-operated tools, medical technology and industrial automation. maxon motor Australia Pty Ltd Contact info and more items like this at wf.net.au/Q303

Thermal imaging camera range The FLIR T400 and T400bx Series thermal imaging cameras combine good ergonomics with 320 x 240 pixel image quality. A compass has been integrated into the T440bx model so building inspectors can see to which direction a wall is oriented.

The cameras come with a tiltable optical unit which makes it possible for users to measure and take images of objects in all angles while maintaining a comfortable working position.

Some models are equipped with the Multi Spectral Dynamic Imaging (MSX) feature, which FLIR claims produces a detail-rich image and produces better texture in a thermal image.

The T440 measures temperatures between -20 and +1200°C, while the T440bx measures temperatures between -20 and +650°C. Objects of interest, both on the thermal image and the visual image, can be highlighted by sketching directly on the camera touch screen. An ‘instant report’ of the inspection - with sketches or other text comments included - can be created directly in the FLIR T440. A programmable button provides easy access to favourite functions.

Built-in Wi-Fi allows connection to smart phones or tablet PCs for the wireless transfer of images or remote control of the camera. The Bluetooth-based Meterlink function transfers readings from external measurement instruments to the thermal image.

All T400-Series thermal imaging cameras come with the company’s Tools software, which allows users to import thermal images directly from camera to PC for basic reporting and analysis of findings.

Heavy-duty connectors ODU's heavy-duty cylindrical connectors are robust cylindrical connectors with threaded and bayonet locking. The heavy-duty connectors are divided into two groups: Series 207, 208, and 209, and the Series 308, 309, and 310 as well as special connectors.

The Series 207, 208, and 209 is a family of cylindrical connectors with threaded coupling system. They are available in three sizes: 207, 208, 209.

Typical applications are areas where mechanical durability, high reliability, small and compact design, and high packing density are of concern. Examples are industrial measurement and control, testing, and power distribution systems.

The Series 308, 309 and 310 offers cylindrical connectors with bayonet coupling system. This family of connectors is also divided into three sizes: 308, 309, and 310. A few connectors can be supplied with watertight mounting flanges for IP 67 protection for up to 8 h submersed at 3 bar, or a neoprene push-pull locking scheme, IP 67 (8 h â&#x20AC;&#x201C;1 bar).

Usage is in severe industrial environments such as heavy-duty crane and lifting equipment at sea ports, container handling equipment, heavy-duty transport systems, mobile cooling equipment, machine tools, railroads and steel mills.

Custom connectors based on any of the above connector systems are available. They can be designed to application-specific requirements in cooperation with the customer. The company will work with the customer to define specifications and establish mechanical, electrical and environmental requirements.

Surge protection device The Plugtrab PT-IQ provides proactive functional monitoring for signal interface surge protection devices. A yellow status signal indicates that the performance limit has been reached as a result of frequent surge voltages, while a small reserve capacity ensures that protection remains effective. The user is informed and can replace the protective connector before the protective function fails due to component overload. Failure is indicated by a red signal. The remote signalling feature allows users to inspect the system from any location and at any time.

The controller assumes the management of a strip equipped with protective devices. It acts both as a power supply and an evaluation unit for all status signals. The system can be easily extended: a controller monitors and supplies up to 28 protective devices via the DIN rail connector. The system can also be expanded to another mounting rail.

The installation design, which includes an integrated rail-mounted bus, allows for quick and error-free assembly. The power supply and status signal are connected as soon as a module is snapped on, thus minimising the wiring effort.

Solar street lights Photovoltaic Lighting Group (PLG) has combined the latest technology in LED lighting with solar power in its UltraLux range of sustainable public lighting.

Solar-energy street lights are simpler and faster to install than traditional grid-connection lighting, says PLG, and with the savings of no trenching, no running of cables and no power bills, plus no greenhouse emissions, it becomes clear how solar lights offer an eco-friendly and economical alternative to traditional grid connection.

UltraLux LED Luminaires range from 25 to 60 W, are made with the latest reflective technology and use American Bridgelux 140 Lm/W high-power LEDs. The mono-crystal silicon solar cell collects the sunâ&#x20AC;&#x2122;s energy during the day and the power is stored in a rechargeable, maintenance-free, deep-cycle battery.

UltraLux solar street lights are set up to run for a full night, with 3-4 nights of battery backup, at zero charge. The light can also be set at the controller to create different desired light running hours or to select dimmable options.

LOW-VOLTAGE HALOGEN PHASE-OUT CHALLENGES The phasing out of the ubiquitous 50 W 12 V MR16 dichroic mirror reflector halogen lamp in Australia poses some significant challenges. Lighting Council Australia estimates there are some 300 million downlights in Australia using these MR16 lamps - hence there is a lot at stake in getting the right replacement for these products.

T

he Australian Government, through the Ministerial Council on Energy, placed a ban effective 14 April 2012 on the importation of 50 W halogen lamps. The ban is part of an ongoing process, through the imposition of minimum energy performance standards (MEPS), to rid the market of inefficient lighting products.

What is loosely referred to as a low-voltage lighting product is also sometimes mistakenly thought of as being ‘low energy consumption’. However, the 12 V 50 W lamp is certainly not an energy-efficient light source - especially when compared to alternative technologies available today. Being an incandescent technology it is hot while illuminated and has been linked to roof cavity insulation fires. Being hot, these lamps also increase the load on air-conditioning systems, adding to their poor reputation for energy efficiency.

24 ELECTRICAL SOLUTIONS - JULY/AUGUST 2012

Replacement options

There are a number of replacement options for the 50 W halogen lamp.

They include: • using the same MR-16 lamp shape except in 35 W • using a MR-16 retrofit LED - the same general lamp shape except with LED technology • replacing the complete luminaire with one of three other available technologies: mains voltage halogen 50 W GU10 base reflector lamp; compact fluorescent lamp (CFL); an LED luminaire The most likely contender to replace the 50 W halogen lamp - at least in the medium to longer term - is LED technology. This is because of limitations with the other lamp types. 35 W halogen lamps and GU10 base reflector lamps are a form of incandescent technology and as such are likely to be phased out because of their inherent inefficiency. CFLs, while highly efficient, lack the aesthetic appeal to

be a mainstream contender and longer term are also likely to be replaced

by LED technology.

The LED challenge

LAMPS:

There are enormous strides being made with LED technology. Governments around the world - and particularly in Asia - are encouraging solid state lighting research and production, in part because of its potential for saving energy, but also because of the anticipated enormous world market. As a consequence, there are literally thousands of start-up LED manufacturers vying for the new business alongside the Asian electronic giants and the traditional European and North American lamp manufacturers.

However, solid state lighting is a complex technology. LEDs are far more technically challenging than the traditional incandescent and fluorescent technologies. Getting everything right in the manufacturing process - from the LED chip to the driver to the heat sink to the light fitting itself - is critical to the performance of the LED. Compounding these difficulties is the immaturity of technical standards and, as noted above, the proliferation of manufacturers and suppliers with little or no experience in lighting.

It should therefore come as not too much of a surprise that there is a lot of underperforming LED product in the marketplace. This is a major issue for the lighting industry. Notwithstanding the increasing availability of high-quality LEDs, there is widespread concern that poor-performing products will sour the market and hinder the long-term take-up of this new energy-efficient but technologically complex light source.

A related concern is the exaggerated claims being made by some suppliers about their LED products. Regrettably, some companies are patently untruthful in their marketing material, particularly in their claims about the light output and colour characteristics of their products.

Government’s response Bryan Douglas, Chief Executive Officer, Lighting Council Australia

Regrettably, the Australian Government has done virtually nothing to date to address the issue of poor performing LED products. The main outcome of a 2010 workshop convened by the Department of Climate Change and Energy Efficiency was an urgent call for regulation. While the department has made tentative steps towards a regulatory regime, nothing is in place yet.

Lighting industry’s response As a consequence of the immaturity of LED standards, the widespread exaggerated marketing claims and the absence of any form of government regulation, Australia’s lighting industry has introduced a voluntary certification program for LEDs called the Solid State Lighting Scheme.

A minimum set of critical parameters is reported by participating suppliers to accurately reflect the performance of their products. Scheme participants provide test reports or other evidence verifying their claims.

Lighting Council Australia registers qualifying product on a database on its website (www.lightingcouncil.com.au) and authorises use of a label indicating conformance to the parameters.

The critical parameters appearing on the SSL Quality Scheme Label are: • luminaire efficacy (energy efficiency of the entire fitting) • light output of the luminaire • measured input power • test voltage • correlated colour temperature • colour rendering index

LIGHT RIGHT: AUSTRALIA CONSIDERS IMPLEMENTING NZ LIGHTING LABEL

A

ustralia is currently examining the option to implement the New Zealand Energy Star program for LED and CFL lighting, said Melanie Slade, Director, Lighting and Equipment Energy Efficiency, Australian Government in her recent keynote address at SPARC Design 2012.

The event is a celebration of lighting design presented by Australia’s lighting industry in conjunction with Vivid Sydney. It showcases some of the best lighting designs in the region attracting allied professions, suppliers and manufacturers in different sectors including electrical contractors, facility managers, building/project management, lighting and industrial design, major end users of architectural, retail and commercial lighting amongst others.

The NZ Energy Star LED specification was launched to the NZ lighting industry on 30 June 2011. The NZ specification is based on the US Energy Star program, which is a joint program of the US Environmental Protection Agency and the US Department of Energy. The star is awarded to around the top 25% most energyefficient products in a category.

The Australian Government is also considering several other actions at the national level to improve energy efficiency. These include: consideration of an interim ‘basic’ minimum performance standard that would be based on currently available international work including international IEC standards and outcome of IEZ4ESSL performance level; consultation with local industry; development of consumer guidance; consideration of cooperation with New Zealand on Energy Star for LEDs. The government is also contemplating reviewing the current minimum energy performance standard (MEPS) for linear and fluorescent lamps and ballasts; examining energy-efficiency measures for circular fluorescent lamps, non-self-ballasted CFLs; considering options for improved energy efficiency for standard commercial lighting luminaires. Australia has already phased out non-compliant, extra-low-voltage halogen reflector lamps and the 50 W dichroic or mirror back reflector 12 V halogen lamps.

26 ELECTRICAL SOLUTIONS - JULY/AUGUST 2012

In her address, Slade said that Australia only produces around 1.5% of the world’s CO2 emissions; but if you look at emissions per capita per person, Australia is one of the biggest emitters in the world. In Australia, 27.4 tonnes CO2 is emitted per person. Beyond reducing emissions, improving energy efficiency can help businesses adjust to competitive pressures through reduced costs, improve comfort levels in workplaces and homes, and help households save money.

While Australia doesn’t compare well in the international context, emissions reductions are being achieved. The country expects to achieve total emissions reductions of 42.6 million tonnes in 2020 by implementing a number of energy-efficiency measures nationally. To be part of the global solution and influence outcomes of international negotiations it is essential that Australia shows some leadership in this field, Slade added. The two key policy tools currently being used to improve efficiency are - minimum energy performance standards (MEPS) and energy rating labels (ERLs).

Opportunities for energy efficiency, said Slade, exist all around us - in homes, businesses, commercial buildings, industrial processes, in our transport system and the energy supply infrastructure. There are several energy-efficiency programs being run nationally to improve efficiency. These include: equipment energy efficiency program (E3); energy-efficiency requirements: building codes, mandatory disclosure requirements: buildings; phase-out of incandescent lighting and inefficient water heaters. These programs form part of the national strategy for energy efficiency which is agreed by the Commonwealth states and territory governments.

The LED lighting technology is developing rapidly but testing of LED products currently available in the marketplace indicates a wide variation in quality and efficacy, noted Slade. Some claims on packaging are misleading and the government is concerned that consumers’ willingness to buy the products in future will be impacted by their experience of expensive, poor quality LEDs. Negative perception could reduce the uptake of efficient lighting and reduce savings that could be gained from adoption of this new technology.

CASE STUDY

Gas-powered, air-conditioning solution to enhance energy efficiency

FMSA, a Melbourne-based company offering comprehensive architectural, interior design and professional construction management services, has reduced its energy usage and costs while improving the efficiency of its building. The company achieved this through an environmental retrofit of its office building in North Melbourne, which included installation of three 85 kW Yanmar gas-powered, air-conditioning systems.

The systems are distributed in Australia by integrated energy company Origin Energy.

FMSA’s building has three office floors, each approximately 400 square metres, plus a basement car park.

The project incorporated several energysaving initiatives, such as an environmentally efficient building management system (BMS), in addition to the Yanmar air-conditioning system. The BMS shuts down the airconditioning system when the windows are open. “The choice of the gas-fired system meant a 50% reduction in greenhouse gas emissions ... while also creating a countercyclical effect on peak demand,” said Michael Fooks, FMSA Director.

The company previously used electric air conditioning, so there were no powerconstraint issues in upgrading to the Yanmar gas-powered variable refrigerant flow (VRF) solution. Preliminary calculations, such as energy use comparisons and carbon emissions, were undertaken

by Umow Lai, a sustainability and engineering services consultancy.

The installation of gas-powered, air-conditioning units was a major contributor to improving the environmental efficiency of the office building, said Fooks. While no formal NABERS or Green Star rating has been targeted, 5 star modelling has been implemented throughout the building retrofit. The primary reasons for implementing gaspowered air conditioning, said Fooks, were sustainability factors and improving energy efficiency. “It is worth giving serious consideration to gas-fired climate control, as opposed to more conventional electric systems. We are certainly pleased with the installers and the result.”

FMSA worked with Greater Pacific Engineering on a design and construct basis. The project was completed with the assistance of the Green Building Fund, which is an Australian Government initiative that aims to reduce the impact of Australia’s built environment on carbon emissions by cutting operational energy usage, focusing on retrofitting existing commercial office buildings.

Accessing the Green Building Fund did not require the project to have a formal NABERS or Green Star rating performed. FMSA was required to model a green building design and show energy cost savings through implementing environmental efficiencies that reduced

energy use. Prior to the retrofit, FMSA’s building was assessed and awarded the equivalent of a conventional 2 stars.

The gas-driven VRF systems are available in sizes ranging from 14 to 85 kW condensers, with some models available in 3-pipe (heat recovery) configuration. These reverse-cycle air-conditioning systems use a gas engine to drive the compressor rather than an electric motor, according to Origin Energy.

The electrical load from condensers is reduced by around 90% and they don’t require three-phase power. A Yanmar 85 kW condenser has a running current of only 8 amps, single phase. A key advantage of these gas-powered models, according to Origin Energy, is their quiet operation as they operate at 62 dBA. While the cooling performance of the gas model is the same as an equivalent-sized electric model, it offers superior heating performance in frosty weather by using heat from the engine to significantly reduce the de-icing cycles often needed with electric models. There is no loss in heating performance down to -10°C. The systems come in a range of sizes to suit anything from a small group of offices up to a 14-storey building.

Receptacle connectors Belden’s Lumberg Automation product range has been extended to include M12 receptacle connectors that can be used to connect control units to ProfiNet/Profibus networks via bus modules as well as to transmit analog data at field level.

Integrated shielding between devices delivers a good level of functional reliability, Belden claims.

The receptacle connectors are available with assembled control cables or with printed contacts for PCB mounting. In the printed contact versions, the integrated shielding ensures flexibility for shield continuity. With the assembled connectors, and depending on the port assignment of the control units, a diagnostics interface can be implemented outside the switch cabinet using an ethernet connection.

This can reduce disruptions resulting from repair or maintenance work. These receptacle connectors are easy to install, due to standardised M12 connection technology and colour-coded bus connections.

Additional features include industrial protection class IP67, high shock and vibration resistance, and a temperature range of -30 to 80°C. They enable available data communication solutions in areas such as mechanical and plant engineering, material handling or public transport.

Versions with assembled control cables are intended for rear mounting.

Saddle clamps The Chainfix saddle clamps, from igus, are designed to fix cables securely within energy chains in moving applications.

Laboratory tests have shown that their tensile strength is around three times higher than that of standard clamps (3500 N compared with 1000 N).

When directly mounted in the energy chain mounting bracket (or through a separate C profile rail outside the mounting bracket), their narrow width and low height make optimum use of limited space. Ribbed plastic saddles ensure a positive connection with the cables, thus securing strain relief. The cables remain clamped, even under large pull, so that they cannot slip out. New and optimised accessories are also available. The part number and correct direction of installation can now be found on the top and the side of Chainfix saddle clamps. This makes identification of parts, for ordering, easy, whether the clamp is installed or uninstalled.

Double igumid G plastic saddles have new locating lugs to make installation easier and more secure. They are abrasion-free and work with a wide range of sheathing materials (PVC, PUR, TPE etc). The clamps are available in black varnished steel or in stainless steel, as a single-, double- or triple-layer version. New Chainfix multiclamps provide four different, double-saddle geometries, allowing the user to install different cable diameters quickly and compactly inside a single, space-saving modular clamp.

These multirow, multiclamps can also securely fix cables with small outer diameters. Double saddles can be ordered individually, to combine existing systems, or as ready to install, multiassemblies, ex stock, or can be configured according to customer requirements.

While Chainfix saddle clamps currently represent standard strain relief for energy chains of all kinds with plastic mounting brackets, igus also offers specialised solutions: Chainfix Nuggets can be used to fix cables and hoses up to a diameter of 20 mm. This space-saving, strain relief element slides easily and quickly into the C-profile rail and requires no installation tools; and, for energy tube application, strain relief separators that combine energy chain interior division components with strain relief.

Managed industrial ethernet switches Weidmuller has released its IES series of industrial ethernet switches. Three ranges are available, with a choice of fast ethernet or gigabit ethernet switches with various port combinations.

Users can select from the entry level IES21 fast ethernet, IES31 fast ethernet with gigabit uplink, up to IES41 full gigabit ethernet switches. The switches have ring redundancy with floating master, security features, IGMP snooping and a built-in virtual cable tester.

Suitable for use in factories, automotive process and oil, gas and renewable energy industries, the range meets all current Australian standards.

The range is equipped with W-Ring technology which simplifies network requirements by eliminating master/slave settings in a redundant ring while providing a network reinstatement time of less than 20 ms.

For additional redundancy, the switches have MSTP, which furnishes the network with spare links that automatically provide backup paths, should the active links fail.

A built-in virtual cable tester (VCT) tests a twisted pair connection status by using time domain reflection (TDR) methodology. Weidmuller claims it is capable of identifying the type of fault, as well as the distance from the switch port, within five seconds.

The managed switches can prioritise network traffic using the 802.1p standard, IP TOS as well as DSCP. The switches are also compatible with SMNP3, Radius and Tacas and are suitable for integrating into CISCO secured networks.

Operational in harsh and demanding environments, the switches can withstand vibration and operating temperatures up to 85°C. Housed in robust metal casings, the range is IP40 protected and can be DIN rail or wall mounted. Weidmuller Pty Ltd Contact info and more items like this at wf.net.au/N943

CASE STUDY

Fuel cell technology to cut carbon emissions

The AIM and ASX listed fuel cell company Ceramic Fuel Cells’ (ASX/ AIM: CFU) BlueGen gas-to-electricity generator was recently installed in one of the UK’s low-carbon homes. The BlueGen unit uses patented fuel cell technology to provide electricity from widely available natural gas. A fuel cell is an electricity generator that converts gas into electricity and heat through an electrochemical reaction, without combustion or noise.

The unit has been installed in a four-bedroom family home in house builder Crest Nicholson’s Noble Park development on the outskirts of Epsom, Surrey. “This is a real first for the UK in terms of introducing fuel cell technology into new homes, and the fact that the technology is now at a point where people can effectively use it in their living environment is something that will bring real consumer benefits,” said Stephen Stone, Chief Executive, Crest Nicholson.

The Crest Nicholson low-carbon home in the UK demonstrates how new houses can meet the energy-efficiency levels of the Code for Sustainable Homes Level 4, cutting carbon emissions by 44% from 2006 Part L Building Regulations levels. In 2016 this requirement for all homes sent to planning increases to ‘zero carbon’, meaning the building fabric of the home and on-site power and heat generation must cut emissions by at least 70% from 2006 levels, equivalent to zero net carbon emissions from regulated energy, which is that used for heating, hot water, lighting and building (services) consumption, over the course of a year.

“The technology works best in energy-efficient homes that require very low levels of heating, and this is exactly the case with the AIMC4 homes at Epsom. Not only that, but as part of this pioneering project we will also be carrying out an intensive program of post-occupancy evaluation, which will provide solid data to help us understand how our customers react to the benefits of fuel cell technology,” states Nicholson.

The BlueGen technology has also been tried and tested closer to home - in the Ausgrid smart home in Sydney’s Olympic suburb of Newington. Over 18 months from November 2010-October 2011, BlueGen generated average of 28 kWh of electricity per day, plus hot water - this means enough electricity for two average homes per year. BlueGen cut carbon emissions by 65%, saving 6.9 tonnes of carbon.

BlueGen, like other distributed generators, needs a net meter to be able to measure the amount of electricity exported back to the grid. If the site does not have a net meter, one must be installed. If the site already has a net meter, typically it must be reprogrammed to correctly measure

www.ElectricalSolutions.net.au

the power export. For consumers to be able to receive the benefits of distributed generation, it must be simple and quick for them to install distributed generation and connect to the power grid.

Each unit can be installed by a qualified and trained electrician and plumber in less than a day. The BlueGen unit needs to be physically installed at the site by a licensed and trained plumber, and connected to the grid by a licensed and trained electrician, according to CFU. The electrician then provides a certificate of electrical safety to the customer. The customer, retailer and the network provider need to complete a number of other steps to get the system up and running.

“This process is unnecessarily cumbersome, long and inefficient.

The connection process can be dramatically simplified and shortened by removing the monopoly on network companies installing or programming meters,” according to CFU. The company suggests that any electrician who has the appropriate grid-connect certification should be able to install or program a meter. “Naturally they would need to cooperate with the network company and notify them of the work done, but this is not difficult or complex. At the truly small scale, eg, 2 kW, the network company is not adding any value or unique technical skill to the connection process. There is nothing needed from the network company which could not be done by a suitably trained and qualified third-party service provider.”

CFU has products installed and operating with customers in nine countries: Germany, the UK, Switzerland, The Netherlands, France, Italy, Japan, USA and Australia. In Australia, the BlueGen units are available for commercial customers through the company’s distributors, Hills Solar and Harvey Norman Commercial division.

Solar conference

The demand for energy-efficient products

Date: 6-7 December 2012 Venue: Swinburne University of Technology, Hawthorn Campus Each year AuSES presents © iStockphoto.com/ Daniel Schoenen the Annual AuSES Solar Conference. This year’s conference will celebrate the 50th anniversary of this highly regarded industry event. Over the two days, the society plans to run two parallel streams of presentations showcasing the diverse interests and specialities of its student and academic members, as well as members from public policy, economics and implementation.

Each day there will be two to three keynotes, and then up to eight 30-minute presentations, in each stream.

As in past years, the event will feature a gala dinner at which the prestigious annual awards are presented to members for lifetime achievement and contributions to AuSES’s mission. This year, the Wal Read Awards for outstanding student achievement will also return.

Subject to sufficient advanced bookings, AuSES plans to offer several field trips in days adjacent to the conference, which will offer opportunities to experience some of Australia’s major renewable energy implementations and initiatives, including Australia’s largest wind farm, energy recovery from waste materials plants and Australia’s first community-owned wind farm.

A small exhibition will support the conference, along with additional presentation activity streams and a full-day seminar for members involved in the design and implementation of PV-based electricity generation facilities.

to go green and battle climate change.

and renewable power sources, such as solar, is expected to rise as the world looks However, the renewable energy industry still faces challenges to continued growth.

A number of industry experts I have spoken to in the last few weeks tell me there are several solar installers in Australia who are not charging the GST correctly - some unknowingly and some knowingly. If they haven’t already, these companies may soon be in trouble with the Australian Taxation Office as the office chases GST debt.

Industry chatter says around one-third of industry businesses might be affected by this issue. If you work in the solar industry and are unclear about how to charge GST, ask your accountant for clarification and/or seek external advice.

This isn’t the only issue affecting the industry. In June, the Queensland government announced changes to the Solar Bonus Scheme. From 10 July 2012, the Qld feed-in tariff dropped from 44 to 8 cents per kWh. The Qld Energy and Water Supply Minister Mark McArdle said modelling of the current solar bonus scheme showed it would cost every household $54 a year by 2014/15.

This would cost Queensland about $1.8bn by 2028 if the bonus scheme remained unchanged at 44 cents per kWh. The industry has welcomed the change, and rightly so.

However, concerns are being raised that the sudden change could negatively impact solar companies.

Mansi Gandhi - Editor es@westwick-farrow.com.au

In my opinion On 1 July, the Australian Government ushered in a new era in which pollution has a price. The Australian Government’s carbon pricing mechanism aims to create an incentive for businesses to reduce their carbon pollution by investing in renewable energy technology or finding more efficient ways of operating. During the initial period, which runs until 30 June 2015, there will be a fixed price of $23 per tonne of carbon. After that period, a flexible price period will commence, during which time a cap and trade system, otherwise known as an emissions trading scheme, will be in place.

While very few businesses in the property and construction sector are likely to have enough emissions to be directly liable to pay under the carbon price, there will be indirect costs. Building materials and electricity, for instance, will be directly affected by rising costs, and other indirect costs such as labour will also increase.

Australia’s commercial and residential buildings generate 23% of the nation’s greenhouse gas emissions - mostly from the use of coal-fired electricity - and this figure is on the rise. Increasing energy prices will drive the property and construction industry to demand higher standards of efficiency and greener materials in an effort to reduce costs. As a result, buildings constructed and maintained to the highest standards will be more desirable for tenants. Similarly, older, less energy-efficient buildings with higher energy costs will face lower demand from tenants.

Australia is already seeing buildings with Green Star ratings yield greater returns than those buildings without ratings. Research from IPD has found that Green Star-rated assets delivered a 12.2% total return last year, compared to 9.7% within the broader market. Once the market adapts to the carbon price, we expect this trend to accelerate.

In a carbon-constrained economy, green building is the way of the future. And for people in electrical trades, this means staying ahead of the game by learning about emerging technologies and installation processes required to gain Green Star certification.

At the Ausgrid Learning Centre in Sydney, for instance, a trigeneration plant produces enough electricity to power 50 houses for a year, as well as heating and cooling energy for the centre. Two hundred and sixty solar panels generate renewable power, while 10 charging stations cater for electric vehicles. The building’s energy-efficiency measures are predicted to cut energy usage to 60% of equivalent-sized buildings, slashing Ausgrid’s energy costs by around $60,000 each year.

However, the building delivers more than energy savings. The 6 Star Green Star Education As Built v1 building is also a hands-on learning resource for both Ausgrid staff and the general public. Among the many interactive inclusions, live displays enable staff and visitors to monitor the centre’s energy and water usage in real time.

As the carbon price kicks in, buildings such as the Ausgrid Learning Centre will become the norm, rather than the exception. Currently, 18% of Australia’s CBD office space is Green Star certified, and more than 500 projects, from hospitals to schools, are registered to achieve Green Star ratings. As we move towards a world where carbon becomes the new currency, electrical contractors with green knowledge and energy-efficiency experience will come out the clear winners.
