Rising power costs, a new energy rating system and the tax on emissions are forcing data centre operators to make energy management a key priority. An electrical contractor can play a key role in this area by helping data centre managers review, control and monitor energy usage.

E

lectrical consultants are privy to a broad scope of functions for their customers. From managing small-scale electrical circuits to designing and deploying multisite data centres, the consultant’s role is critical to customers’ operational success. In Australia, one of the central themes evolving over the past decade of rapid infrastructure growth is efficiency. This has been manifest in different forms over the years, from improving efficiency to reducing cost, to managing efficiency to improving availability and now, in its most recent guise, improving efficiency to manage carbon emissions. The industry is on the frontline of carbon trading schemes and carbon ‘taxes’, not only in Australia but around the world. As governments continue to explore and implement carbon emissions standards and carbon reduction commitments, many companies will be required to participate in auction-based carbon emissions trading schemes that are designed to provide economic and reputational incentives for achieving reductions in emissions. Often these schemes take the form of a selective industry tax, as is the case with Australia’s recently implemented carbon tax. But regardless of how it’s implemented, managing carbon emissions has become a major cost factor for numerous large industries. In many cases, those companies that do not reduce emissions could face financial penalties in the form of emissions credits they will need to purchase. They could even have their performance published in an annual league table in relation to other scheme participants. Contractors play a very particular role that can have a significant impact on customers’ abilities to mitigate the effects of a trading scheme or carbon tax, without compromising availability of performance.

Sizing up the challenge Often the first step in managing change of this scale is: understanding the scale. If we don’t know what we’re dealing with, it’s very difficult to manage it effectively. In broad brushstrokes, Australia’s carbon tax has committed the government - and by extension organisations operating in Australia - to reduce carbon emissions 5% below 2000 levels in 2020, regardless of what other countries do, and preferably by up to 15 or 25%, depending on the scale of global action. These targets will require cutting expected emissions by at least 23% relative to business as usual in 2020. What this means quantitatively for individual organisations is, at this stage, unknown. What is known is that the cost of doing business is going to increase due to increases in costs of raw materials and commodities that contribute to carbon emission, such as power. Even if these costs are offset by savings in the form of tax rebates or other vehicles, the fundamental designs of our data centres in the future will need to be carefully considered in terms of their environmental impact, and public impact. That latter concept, the public impact, is worth mentioning here. We don’t work in a vacuum, and even if in the long term we discover ways to limit the ‘hit’ of a carbon tax on our customers’ bottom line, the perception of how we do business with respect to the environment could be just as important as the cost. We therefore need to know how every aspect of a data centre design - from the equipment to the critical support infrastructure - is impacting the new carbon tax ground rules. Often a simple way to understand the scale of change possible in a legacy facility is to conduct a data centre audit, which will provide a good starting point for your

DATA CENTRES

customer in understanding their current energy consumption and data centre performance. From here some basic improvement measures can be set and a range of solutions identified to optimise their data centre elements and improve energy efficiency.

What we know Data centres have traditionally been designed with extra headroom to accommodate growth, but during the last decade demand escalated so quickly that added IT capacity consumed available headroom and outpaced supply in terms of floor space and power and cooling capacity. These changes were further exacerbated by the increased focus on data centre energy consumption. With both the density and quantity of servers rising, data centre energy consumption became a significant factor in terms of IT cost management and, in some companies, response to concerns about global warming. Early efforts to reduce data centre energy consumption focused on reducing costs around cooling, which accounts for a third of energy consumption. Subsequent efforts took a more holistic approach that recognised the interdependency of data centre systems and shifted the focus to the IT systems that create the need for cooling. Today, data centres have reached a level of complexity beyond the point where we can point to one or two factors that alone would significantly impact the carbon emissions of the facility. Fortunately, we don’t have to, because technology - in the form of facility-wide management tools - gives us an eagle-eyed view over every aspect of our customers’ data centres, and specifically, the carbon output of every interdependent systems we’re managing. Of course, going from a reactive to a proactive approach to infrastructure monitoring and management requires a new type of management system that provides visibility into the data centre’s physical infrastructure within both the IT and facility domains and across these two domains. This shift gave birth to the idea of data centre infrastructure management (DCIM), a superset of infrastructure monitoring that encompasses the ability to manage the data centre’s physical infrastructure to optimise resource utilisation, efficiency and availability. By enabling management across the gap between IT and infrastructure, data centre operators have visibility into the true capacity of their IT and infrastructure systems, allowing them to manage closer to actual capacity, rather than the conservative estimates that leave some percentage of capacity unused as a buffer. More importantly, these tools help customers gain more visibility and control of their data centre. Gaining control of the infrastructure environment leads to an optimised data centre that improves availability and energy efficiency, extends equipment life, proactively manages the inventory and capacity of the IT operation, increases the effectiveness of staff and decreases the consumption of resources. And, in the frame of this discussion, contribute to the containment and reduction of carbon emissions.

An informed approach The key to achieving these performance optimisation benefits is a comprehensive infrastructure management solution that improves the visibility that a customer has of the performance of their data centre.

A data centre assessment provides insight into current conditions (read output quantities) and opportunities for improvement. After establishing that baseline, data centre infrastructure monitoring will collect power, temperature and equipment status for critical devices in the rack, row and room. Data is continuously collected to not only provide a window into equipment and facility performance, but point out trends and prevent problems wherever they may be located. For example, if an unmonitored branch power circuit operating at 80% or more of full capacity has a load blindly applied, it could cause the distribution breaker to trip, powering down that entire distribution leg. Or take the addition of blade servers to an unmonitored rack. Users could be at the thermal threshold of heat creep, unknowingly subjecting systems to potentially serious problems. Another example involves batteries, often described as the weakest link in the power chain. The best way to determine a battery’s health without discharging it is to use a monitoring system that measures the internal resistance of all of the cells in the battery, using an integrated battery monitoring service that combines state-of-the-art technology with proactive maintenance and service response. Infrastructure monitoring provides this real-time control, historical performance trending, alarm notifications and event escalations to minimise or eliminate downtime. In addition, users can manage energy consumption through thermal and power metering. Through optimisation of data centre elements and design, a comprehensive infrastructure management system can help data centre managers improve equipment utilisation, reduce server deployment times and more accurately forecast future equipment requirements, resulting in operating and capital expense reductions. Managers not only improve inventory and capacity management, but also process management, ensuring all assets are performing at optimum levels. In turn, this minimises the impact of carbon emissions per node, given that emissions are now becoming part and parcel of any efficiency calculation. Effective optimisation can provide a common window into the data centre, improving forecasts, managing supply and demand, improving levels of efficiency and availability.

Clearing the air During the data centre’s next decade, opportunities to improve efficiency, optimise performance and protect the environment will exist throughout the three cycles: design and deployment, operations, and management and planning. Data centres moving to a higher density IT space can improve efficiency and avoid compromising availability, as the higher density puts additional stress on the power and cooling infrastructure, by using the visibility and control that comes with comprehensive infrastructure management. It all starts at the design and deployment stage, where we can leverage pre-engineered solutions and high-density architectures to reduce the time, space and capital required for construction of the building. During operation, we can reduce costs by using efficient technologies and strategies while simultaneously decreasing downtime costs by employing high-availability configurations. And additional savings are possible by using infrastructure management controls to streamline operations and facilitate a comprehensive maintenance program. Ironically, the key is to look beyond carbon emissions alone when considering efficiency and to take every opportunity throughout the life cycle of the data centre to achieve efficiencies, without compromising performance.

CASE STUDY

O’Donnell Griffin’s LV installation for Melbourne Water Following 13 months of critical execution to keep complete functionality of Melbourne Water’s Western Treatment Plant that processes more than 52% of Melbourne’s waste water, engineering solutions provider O’Donnell Griffin completed the electrical works component of the wet weather upgrade project in December 2011. In August 2011, O’Donnell Griffin also secured the LV Installation Package (Northern) contract as part of Melbourne Water’s Eastern Treatment Plant Tertiary Upgrade Project. The company has already won the NECA Victoria Industrial Project - Large category for the project. “The company used specialised equipment and systems to create an outstanding plant,” said NECA. The project was a part of the plant’s $418 million transformation into one of the most sophisticated, large-scale sewage treatment facilities in the world. The transformation is being delivered by the Eastern Tertiary Alliance - a partnership between Baulderstone, UGL, Black & Veatch, KBR and Melbourne Water. Since its opening in 1975, the Eastern Treatment Plant has supported Melbourne Water’s Western Treatment Plant by treating 40% of Melbourne’s total sewage to a ‘secondary standard’ in a process that involves screening and sedimentation to remove litter, grit and sludge, followed by biological treatment and disinfection with chlorine. The current upgrade involves the construction of seven new structures, including the ozone production facility, and an addition of a third ‘advanced tertiary’ treatment stage. Tertiary treatment uses ozone - generated on-site from oxygen - to disinfect the effluent and reduce colour and odour. Biological filters then break down any organic matter and reduce contaminants such as ammonia, foam, grease and litter before more ozone is added and ultraviolet light is used to further disinfect the effluent. The project is expected to deliver significant environmental benefits by improving the quality of the plant’s discharge at Boags Rocks, on the Mornington Peninsula, and increasing the standard of recycled water produced at the plant. This project had a limited timeframe prior to commencement on-site. Upon appointment, O’Donnell Griffin was quickly required to allocate all resources and facilities to complete electrical works at the newly constructed ozone production facility. O’Donnell Griffin allocated an onsite management team, a suitable number of capable and experienced resources, and plant and equipment. It was a challenge but the company achieved it successfully. It also meant the company had to monitor its resources constantly to ensure all demands were always met with an adequate supply. O’Donnell Griffin completed the LV Installation Package (Northern) contract in April 2012 - on time, within budget and with zero lost time incidents (LTI). The scope of works required O’Donnell Griffin to supply all labour, plant, equipment, administration, consumables, supervision and verification necessary to carry out the LV Installation Package (Northern) works. Initially based on preliminary cable ladder routes, cable schedules and power/lighting layout designs, the scope was ultimately divided into two key areas - the Ozone Area and the TSPS Area. Forming part of the Ozone Area were: LV and HV switchrooms, a PLC room, UPS room and control room; a cooling water pump station - to provide cooling water for the removal of heat from the ozone and oxygen

generation process; a liquid oxygen area - to store the backup source for the ozone generation process; a pre-ozone injection area, post-ozone injection area, contractor area and ozone destruction skid - to manage all stages of ozone injection; generator room - to convert oxygen gas into a low concentration ozone mixture. The Ozone area also included variable pressure swing adsorption (VPSA) rooms 1 and 2 to serve as the primary oxygen generation equipment, purifying ambient air to produce oxygen gas and a pump room to house the cooling systems for the oxygen and ozone generation process, as well as the plant instrument air system. The TSPS Area comprised a switchroom and a PLC room, together with a primary pump station which extracted semi-treated water from the forebay and pumped the water into the tertiary filtration plant. In delivering the detailed scope of works, O’Donnell Griffin managed, installed, tested and commissioned all 400 V switchgear and associated 6.6 kV switchgear as well as PLC/communication panels, vendor-supplied control equipment, motors, local control stations, field instrumentation and communication systems. Using an extensive, pre-installed underground and in-slab conduit system, the team was principally challenged to install and test approximately 1800 associated electrical cables. This was achieved through a highly coordinated process of guiding the supplied cables to the selected location, opening pits, installing the cables and rescheduling other works to ensure continuity of work. Most instrumentation and wet racks were also installed, wired, tubed and calibrated. Additionally, the team was responsible for the installation and termination of various systems and networks, from the variable speed drives, earthing systems, distribution boards and Profibus communications network to the light and power system, and UPS and battery charger systems. Each piece underwent testing and certification prior to its installation. While the general electrical design of the project was supplied to the team, O’Donnell Griffin was instrumental in assisting to identify, recommend and resolve the best on-site installation methods. The technical elements of this project were complemented by O’Donnell Griffin’s ability to provide the essential management services necessary to successfully deliver the project requirements. The greatest difficulty encountered by O’Donnell Griffin was the scheduling of works, as is typical of a large-scale, multidisciplinary project. The team was required to continually maintain suitable manning levels to achieve measured milestones. The company’s customer held management meetings on a weekly basis to ensure a constant flow of information was achieved with all stakeholders. Combined with two-week forecasts and a detailed project timeline, the regular communication ensured no unscheduled electrical and mechanical service interruptions occurred on-site throughout the entire seven months of installation works.

CABLING PRIORITIES

TRENDS IN FIBRE AND COPPER CABLE TERMINATION In the contractor world, the termination process is probably the most important aspect of network installation. In this article, Mark Putica* explains different termination and installation procedures and elucidates the pros, cons and trends in cable termination to help you make the right decision.

W

ithout the right tools and knowledgeable staff, the installation process can be a total disaster and can drastically prolong the project completion and handover to the end user. In addition, by using outdated installation and termination procedures on today’s bandwidthhungry networks, the installer can be drastically slowed down and ultimately add significant cost to the overall process. So what are the most efficient termination methods? This would be easier to understand by looking at the most commonly used technologies and tools on offer to contractors.

Fibre installation For years, installers in the Australian and New Zealand telecommunications industry have been using epoxy and polish technology for fibre installation procedures. This incorporates glueing of fibre into the connector with epoxy and polishing the end with a special polishing film. It is a good long-standing process with lowest costs, especially if a lot of connectors are being installed. However, it’s a slow process and may even need to set overnight. Overall, it is not as high-quality a termination process as fusion splicing. The other, most commonly used method is fusion splicing. It is a process of fusing or welding two fibres together, usually by an electric arc. While it is the most expensive prepolished cable and connector termination method, it is not as convenient because it requires power and can be challenging for installers depending on the job location. The advantages of this method include lower loss, least reflectance, and strong and reliable joints between fibres. Just about all singlemode splices are

fusion. Multimode fibres can be challenging to fusion splice as the larger core with many layers of glass that produces the graded-index profile are sometimes harder to match up, especially with fibres from different types or manufacturers. Several different types of terminations are available for multimode fibres. Each version has its advantages and disadvantages, so learning more about how each method works helps decide which one to use and when. With the current key requirements of termination process being speed, quality of terminations and of course the cost of tooling, TE Connectivity has developed a quick termination technology program (QTTP) for installers. This technology program provides the installer with the right tools to perform by far the quickest and consistent fibre, UTP/STP copper and cable installations. LightCrimp Plus is a simple mechanical process to terminate optical fibres for premises cabling and fibre-to-the-desk applications. With LightCrimp Plus, fibres can be terminated without epoxy, polishing papers, ovens, UV lamps or electrical power for field termination tooling. As enhanced services such as 10, 40 and 100 Gbps ethernet require a high-quality controlled end face, the epoxy and polish technology will not be sufficient in future. The IEC 60874-19-1 standard specifies the dimensional details of fibre-optic connectors in order to ensure interoperability and performance within an ISO 11801 specified application. These dimensional requirements are directly related to the end-face characteristics of a polished ferrule, namely its radius, dome offset and fibre position. If these ferrule characteristics are optimal, an optimised physical contact (OPC) between two connectors is

guaranteed. This will enhance data transmission parameters like optical performance, attenuation, return loss and data link stability. Also, the optical interoperability between connectors of different suppliers can be ensured by controlled end-faces. As a result of OPC, a stable physical contact between the end-faces is achieved. This provides a very low insertion loss as well as a high return loss in order to run high-speed applications like 10, 40, 100 gigabit ethernet.

Copper installation Copper is still the preferred medium in most parts of IT networks and the number one interface on devices such as personal computers, notebooks, IP devices, switches and servers. As an installer, we can also say we are lucky that copper termination and installation is far easier than fibre. Connecting cables to patch panels, traditional push-down blocks or commonly to the jacks may prove to be time consuming when using tools such as knives, cutters or scissors. In contrast to fibre installations, there is one most commonly used tool in copper installations - a punch-down tool or, as many installers refer to it, a krone tool, which can be used to terminate cross-connect jumpers and cable runs at patch panels, disconnect modules and 110 blocks. This mechanical handheld tool is simple to use and can effectively and speedily cut through wires. It has a strong handle that allows firm gripping during punch-down movement. Once the wires are stripped off from the insulating and protective casing by the installers, they are placed on patch panels or push-down blocks, and the tool is then positioned on top of the wires and pushed to set the wires in place. A similar procedure is followed

for termination of jacks. This punch-down technology has been working well for years but is becoming outdated as technology advancements in termination tooling emerge. New UTP termination methods take the existing krone punchdown tool and put it in the form of multipair (4 pairs at once) termination technology. It simultaneously terminates and trims all four pairs of conductors in one effortless action. This allows the installer to be faster - resulting in on-site job efficiency. Furthermore, you can rest assured all four pairs have been terminated with consistent quality and accuracy. One example of such technology is the MultiMate tool. Shielded termination is a little more complex and time consuming if the right tool is not used. With the stringent requirements for 10 and 40 Gbps, careful attention needs to be paid when terminating shielded cable. Many untrained installers who are in a rush to complete a job still terminate the cable incorrectly. The most common method of terminating the shielded cable is by using a punch-down tool. If you or the end user is going to the effort of installing a superior cable solution, then you really have to make sure the terminations are done carefully and there is no interference at the jack level. An SL Tool is available on the market for quick shielded terminations. Three factors can contribute to most installation inconsistencies: lacing the conductors, maintaining pair twists to satisfy standards and producing consistent terminations. The SL Tool comes with a belt holster and an integrated jacket stripper to cut and remove the cable jacketing and foil/screen. This means there is no need to put the tool down and reach for another, thus increasing the time a technician can spend on the actual termination even further.

Cable installation This is one aspect of network deployment which seems to have been forgotten by manufacturers and no development has been made to simplify this process for installers. Most of the installation contractors use cable which comes in traditional cardboard reel boxes of some sort. However, a newly launched cable reel, ReelSpeed, specifically created to provide contractors with an easy and efficient method of cable installation, is available. The Australian-designed ReelSpeed is manufactured with six interlocking pieces that fit together without mechanical fasteners or adhesives and is produced from polypropylene and glass fibre. *Mark Putica, Regional Marketing and Communications Manager for Australia and New Zealand, TE Connectivity.

CABLING PRIORITIES

• All PV array switch-disconnectors are readily available (Clause 4.4.1.4) and are to be marked with an identification name or number according to the PV array wiring diagram. They shall have a clear indication of isolation position “off” and “on” eg, O and I. (Clause 5.5.1) • When the PCE has an internal means to isolate the solar array this switch-disconnector shall be mechanically interlocked so that it will isolate the array if repair or replacement of a module is to be carried out within the PCE. (Clause 4.4.1.2) • Where multiple disconnection devices are installed they are either ganged so that they all operate simultaneously, or grouped in a common location with a warning sign indicating the need to operate all switch-disconnectors to isolate the equipment. (Clause 4.4.1.3). © iStockphoto.com/ Pedro Castellano

Earthing

• Are protected from abrasion, tension, compression and cutting forces. (Clause 4.3.6.3) • Plastic cable ties are not to be used as a primary means of support. (Clause 4.3.6.3) • Ensure wiring in enclosures and cable entries maintain the IP rating and are sealed to manufacturers specifications and double insulation between conductors is maintained and installed in such a way as to minimise strain on the connectors. (Clause 4.4.4.4) • Connectors are mated with connectors of the same type from the same manufacturer. (Clause 4.3.7) • String fuses in PV arrays are rated for DC (Clause 4.3.1) and are rated to interrupt fault currents from the PV arrays. (Clause 4.3.4) • Fuse holders shall have a current rating equal or greater than the corresponding fuse and provide protection suitable for the location. (Clause 4.3.9.1)

(Clause 4.4.1.4) • An isolating/disconnection device shall be installed adjacent to the PCE. (Clause 4.4.1.4) • Disconnection devices will be not be polarity sensitive and must operate in all active conductors. (Clause 4.3.5.2) • If circuit breakers are used they are not to be polarity sensitive. They must also be rated to interrupt the full load when operated and have a voltage rating greater than VOC. (Clauses 4.3.1 & 4.3.4) • Must be certified to AS/NZ 60898 or IEC 60947. (Clause 4.3.5.2)

PV module and mounting frame earth connections are to be a purpose-made fitting providing earthing or bonding connections or purpose-made penetrating washers or equivalent between the PV modules and mounting frame for the connection of dissimilar metals purpose-made fittings are installed to manufacturer’s instructions. (Clause 4.4.2.2) • Cable lugs, earthing termination and bonding cables are to be fixed by stainless steel bolts, washers and pentrating washers to aluminium frames. (Clause 4.4.2.2) • Earthing or bonding connections must be arranged so the removal of a single module earth connection will not affect the continuity of the earthing or bonding connections to any other module. (Clauses 4.4.2.2 & 4.4.2.3) • Self-tapping screws cannot be used for earth connections to the PV array framework. (Clause 4.4.2.2)

PV array functional earthing Connection to earth is at a single point, connected to the main earthing terminal of the electrical installation. This connection point is between the PV array disconnection device and the PCE and as close as possible to or located inside the PCE (Clause 4.4.3.1). The PV system functional earthing conductor has the same rating as the earth fault interrupter EFI (Clause 4.4.3.2).

LV PV arrays with functional earthing On an earth fault the EFI interrupts the earth fault, shuts the PV system down and provides a fault indication and an external fault alarm. (Clause 3.4.2) The standard also includes requirements for system documentation and commissioning.

CASE STUDY

Westfield deploys energy-efficient lighting solution

T

he retail property group Westfield’s corporate headquarters under the iconic Centrepoint Tower were designed to minimise the use of natural resources, provide a more productive and comfortable workspace for staff and target a 5-star NABERS energy rating and a 6-star Green Star rating. It was essential that the lighting architecture would meet the project’s green criteria and complement the environmental design ethos of the building. Westfield wanted the lighting system to reduce the energy requirement for lighting as well as enhance the working environment by maximising natural light where possible. Vital to achieving these efficiency goals was the installation of Philips Dynalite specified Digital Addressable Lighting Interface (DALI) technology. The technology is simple to install and commission and monitors and controls lighting within the office environment, which significantly reduces the use of energy. Energy costs are lowered through daylight harvesting and standard controls such as dimming and occupancy sensors. Rather than depend on staff to turn off the lighting, the intuitive DALI system does it. Each luminaire in the building is individually addressable, which delivers flexibility in control and monitoring. Lights can easily be grouped, ungrouped and regrouped into different control areas without the need to reconfigure any fixed control wiring and redundant lighting can easily be temporarily disabled. The entire system is centrally monitored through the building management system (BMS), which allows the automatic identification of failed lamps and ballasts. The installation of dimming luminaires around the perimeters of the office enables artificial lighting to be increased or decreased to balance natural light levels. Switching was used in the building core where natural light levels were too low. To optimise energy efficiency, lighting is fully automated during normal office hours. The lighting control system is interfaced through a Philips Dynalite DDNI-BACnet switching device to the main building management system (BMS). After hours, the BMS assumes global control over the lighting controls - along with HVAC and security systems - and is able to switch off the lighting after a preset time. Dynalite DPN eight-button user interface panels were installed near the lift areas

to allow staff to activate lighting when needed. The DPN panels were installed in the boardroom to allow the selection of preset lighting scenes such as ‘conference’, ‘presentation’ and ‘meeting’. A Philips Dynalite DTK622/RS232 AMX interface allows control of the audiovisual systems through the system and also allows supervision of the lighting through the AMX controls. The Philips Dynalite’s Mapview software, which is accessed through a head-end computer in the security area, helps monitor, manage and - when required - reconfigure to meet changing needs within the building over time. The solution helped Westfield achieve both a 5-star NABERS Energy rating and a 6-star Green Star rating. The lighting system allows the building to make intelligent decisions about the optimum delivery of light. Lighting controls can switch lights off when no one is around, automatically adjust lighting levels based on the amount of natural daylight in the space and turn off or dim lights, based on the daily cycle of the office. The perfect control of the lighting means that the least possible amount of light is supplied when needed. Together with the many energy-efficient building and services designs that have been included in this project, the lighting control system has helped reduce energy consumption by 30%. In total, 300 DALI fittings were installed in the 32,000 m2 space. A combination of fluorescents and LEDs was used, with 64 channels of switching controlled through the Dynalite DMRC210 relay fixture couplers and the remaining 236 channels of dimming controlled through Philips’ Dynalite DDBC300-DALI ballast controllers. A single lighting control network was used, with the Dynalite DDNG485 network bridges used to connect each floor’s subnetwork into the sophisticated Philips Dynalite peer-to-peer communications Dynet RS485 trunk network. A combination of Dynalite DUS804C and DUS804C-UP universal sensors was used for both lux levels and presence sensing.

Power quality eBook With equipment and energy costs rising, it’s hard to stress enough the importance of power quality. Power quality issues can hamper production processes, damage costly equipment and lower productivity. This eBook features articles on power quality challenges, managing and reporting problems, improving efficiencies and reducing costs. Download now.

Compact Coriolis flowmeter Yokogawa Electric Corporation has released the Rotamass LR Coriolis mass flowmeter. Designed to measure both liquids and gases, the effective turndown of the flowmeter is no less than 2000:1 for liquids and 5000:1 for gases and the mass flow measurement range spans from 1.5 g/h to 40 kg/h, achieving a measurement accuracy of ±0.15% for liquids and ±0.5% for gases. The flowmeter’s dual bent tube optimally decouples the core measuring element from process vibration that can cause fluctuating zero stability and decrease measurement accuracy. When fluid density changes, a single-tube Coriolis flowmeter can become unbalanced and start to behave like an emitter. The Rotamass LR remains balanced due to the equal mass change in both tubes and the absence of interference from the process piping. By design, it is insensitive to fluctuations in the ambient temperature

and achieves good zero stability under changing process conditions.

Unified communications (UC) has many potential benefits for organisations, including cost savings through the use of IP telephony as well as streamlined communications between staff members and customers. This eBook features several articles on emerging movements in UC - download now!

The two tubes are made from C-22 alloy, which is less susceptible to thermal expansion than conventional stainless steel. Normally it is more difficult to measure temperature with Coriolis flowmeters that have tubes with a smaller surface area. The Rotamass LR uses an inline temperature sensor, ensuring precise and fast measurements in process temperatures ranging from -50 to +150°C.

Global networks for M2M M2M has a relatively short history, having been around since 2000 when it became apparent that communication between machines carrying out similar functions would be a good idea. It has since broadened into communication between dissimilar devices, examples being medicine and mining. This eBook explains more about this technology.

The flowmeter has a gas-tight, all-stainless-steel secondary containment that can handle pressures up to 65 bar. It can be used in high-pressure applications up to 400 bar. The flowmeter does not use gaskets, minimising the risk of leaks. Insulation and a heat jacket are available as options.

CASE STUDY

Improving power quality at mine sites

A

project within the CRCMining Power Management program based at the School of Electrical Engineering at the University of Newcastle has collected voltage and current information in an underground offshore coal mine at the substation (power centre) level into which the mine’s continuous miners are connected. The work is part of an investigation into voltage stability and its effects on both production and maintenance. The data collection box, designed and built in Australia by the University of Newcastle, collected information well over the 100th harmonic in an attempt to capture transients associated with switched power factor correction capacitors and harmonics associated with variable speed AC drive units not fitted with active front end filters. Modelling of a target mine in CRCMining’s ‘Statcom’-based voltage stabilisation project had indicated significant voltage transients would be found as a result of switched capacitors and this was proved to be both correct and accurate. However, the level of harmonic distortion was substantially higher than had been anticipated and is now the subject of further studies. A quick analysis of the collected data indicates very high levels of 5th, 7th and 11th harmonics, which can considerably decrease the life of both power system components such as transformers and connected motors due to heating. Contributing components to these harmonics may include variable speed AC drives as well as core saturation of transformers in the system, which was previously not considered in the mix of potential issues. Overvoltage transients of 600 V were measured, associated with capacitor switching, and undervoltage issues associated with line impedances have been verified, validating the mine model developed by the university for the Statcom project. An interesting question raised by the results is whether a ‘stiff supply bus’ would have any effect on the data. While heavy dynamic loading of weak supplies will cause voltage fluctuations for equipment, the observed harmonic distortion could be generally unaffected by the stiffness of the connecting supply considering the line impedances between miners and their grid interconnect. Electrical engineers in mining have welcomed the results, which they believe are very timely given the industry’s rate of adoption of variable speed AC drives. It is believed increased nuisance tripping of conveyor belt drives and earth leakage detection failures are possible outcomes of not fully understanding the dynamics of the underground mining power distribution system as well as the obvious maintenance and life cycle issues of equipment.

Current work is focused on three main areas: developing a range of predictive condition monitoring tools (DC and AC motor duty meters and novel power quality measuring tools); identifying power supply and reticulation weakness to understand their effect on production and equipment, then providing voltage support and harmonic correction solutions; and, extending the interoperability capability of the CRCMining Power Management group by using mine precinct data to determine the key elements of mixed energy generation, with a view to optimising operational cost, power delivery capacity and power quality. Mine planners will be able to draw metrics for the development of power systems and researchers can focus on issues affecting operational capabilities to provide new and innovative solutions to optimise energy delivery and cost. The second area aims to understand mine precinct power requirements driven by diurnal, shift, week/weekend, seasonal and product impacts, and matching this varied demand with grid supply options. This includes an assessment of interoperability between conventional, renewable and hybrid supply solutions. CRCMining conducts projects within a number of key research, development and demonstration programs with its members. The programs currently span the areas of automation, power and equipment management, rock fragmentation and handling, and coal technology and fugitive emissions. CRCMining members come from mining end users (Anglo American, AngloGold Ashanti, Barrick Gold Corporation, BHP Billiton, Newcrest Mining, Newmont Mining, Peabody Energy and Xstrata Coal), original equipment manufacturers and service providers (Caterpillar, CSC, Herrenknecht, Joy Global and Sandvik) and from the research providers at the Universities of Newcastle, Queensland, Western Australia and Curtin University.

gets a makeover and transforms into ECD Solutions. ECD stands for electrical, comms and data. The aim of the relaunch is to cover the ever-expanding and diversifying role of electrical contractors, and make the magazine more useful and relevant to readers. The relaunch in no way means there will be reduced focus on the topics we already cover, such as energy efficiency, solar power and electrical distribution. The revamped magazine will feature regular sections on energy efficiency and renewables, data and communications, electrical distribution, automation and security - the areas that you, our readers, see opportunities in. The other key change is that the new magazine will have a new editor. I’m heading off on maternity leave and will temporarily hand over to Dannielle Furness, who has worked closely with the lighting industry.

In my opinion Out-of-date equipment, rapid data growth, a requirement to reduce energy output and saving money are all issues currently facing IT, data centre and facility managers. This is why now, in today’s highly connected and technology-dependent world, it is vital for organisations to start making the right and ‘green’ data centre decisions.

A.B.N. 22 152 305 336 Head Office Cnr. Fox Valley Road & Kiogle Street, (Locked Bag 1289) Wahroonga NSW 2076 Australia Ph: +61 2 9487 2700 Fax: +61 2 9489 1265

It is not uncommon for a data centre today to be faced with rising energy costs combined with a need to increase size, sophistication and/or density - all of which present new challenges for managers under pressure to continually improve performance and reduce operational expenses. In this environment, IT and data centre managers must have access to accurate and timely information about their assets, resource use and systems status - from granular infrastructure to high-level overviews, while also meeting operational demands in an energy-constrained environment.

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

This level of complexity requires a new approach: closer collaboration and a more cohesive partnership between IT, facilities and building managers. Rather than isolate this process of energy management as an IT-only operation, organisations are starting to see that others involved in powering and connecting a building must be brought on board to get the best results and deliver energy savings right across the building.

Art/Production: Tanya Scarselletti, Jeanette Teuma, Colleen Sam

Many data centres are managed with loosely aligned tools for IT and facility management and this needs to change in order to gain better operational insights to make more informed efficiency decisions. The stats around energy consumption are pretty sobering. Right now, buildings worldwide represent 42% of all electricity usage, and by 2025 they are projected to be the largest emitters of greenhouse gas emissions on the planet. IT is the main culprit of this electricity consumption - currently between four and eight per cent of electricity consumption goes into IT kit; by 2030, it is expected to jump to 40%. Armed with these forecasts, IT managers can now see more clearly that energy management - which is all about optimising an organisation’s energy use by implementing strategies for energy efficiency, reliability and monitoring - is an absolute must-have tool within their operational arsenal. A key step in promoting such collaboration is to acknowledge the ‘interconnectedness’ of today’s data centre. No longer physically confined to the IT room, the data centre branches out into the building and, as such, becomes the concern of all those managing a building. It becomes the responsibility of IT, facilities and other maintenance contractors to avoid such issues and achieve maximum energy efficiency gains. To get there, all parties involved in the upkeep of a building need to see the same, real-time information: this is how much electricity is being consumed, and this is who or what is consuming it. Armed with such facts, the groups can more easily work together to arrive at energy-saving solutions. So where does this information come from? One example is deployment of a software, such as Schneider Electric's Struxureware software, that provides a single view of all energy consumption across the entire building. It is relevant for both IT and facilities, and the two groups can use the insights gained from the data to make strategic decisions about energy allocations. Electricity usage is a controllable cost in a building. Yet it is only controllable when all players responsible for its usage work together to control it. As such, the future demands a situation whereby all work together to tackle the issue of energy consumption as a united front. Paul Tyrer, Vice President, Pacific, Schneider Electric IT. Tyrer has over 16 years’ experience with Schneider Electric (working with APC by Schneider Electric). His experience in driving cross-business collaboration projects at Schneider Electric has resulted in significant energy efficiencies for customers both inside the data centre, through to the critical buildings that house them. Tyrer, along with the broader Schneider Electric team, believes there is a great opportunity to reduce energy consumption across business-critical infrastructure as the Pacific looks to transition to a low carbon economy.
