Power protection

A complete solution for control, protection and monitoring of grid-connected solar photovoltaic (PV) plants.

The Smart String Box bundles Carlo Gavazzi surge arrestors, power supply and EOS array master module, string controller, environmental module and I/0, together with a third-party isolator device, all packaged in an IP66 rated enclosure. It is ideally suited to installations ranging from 10kW-120kW and manages up to 250A of total string current.

Smart String Box systems can be fused on both the negative and positive side. Innovative new Carlo-Gavazzi DSF surge arrestors embody a special internal backup that ensures they remain safe at the end of varistor life, thus ensuring the safest transient overvoltage protection for combiner boxes.

Carlo Gavazzi’s recently-introduced Eos-Array controller is flexible, easily scalable and is composed of a series of modular elements to provide efficient local and remote control of a solar plant, targeting small to medium or high power installations.  With no auxiliary bus wiring, the system is simple to install and straightforward to expand.  Further cost saving is provided by the integrated string fuse protection and modularity also improves overall system reliability. String efficiency and inverter performance are monitored, enabling operators to rapidly isolate faults, failures and inefficiencies as soon as they occur.

Built-in independent monitoring provides basic or comprehensive plant control and monitoring on DC and AC sides. The expandable system gathers accurate and dependable data to help maintain an efficient revenue stream from PV installations.  Controllers promptly advise users of events such as blown fuses, PV module disconnection or inverter failure, to enable rapid maintenance measures to be carried out, significantly reducing service time and missed production costs.  There is no monthly charge for the data, which is stored locally to give users full control.

Monitoring systems also provide users with information including calculations of DC-to-AC conversion efficiencies and Balance of System. In addition, solar irradiation, wind speed and PV temperature are recorded and available for analysis. Data are displayed in graphical and analytical format and in real time.
Alarms can be set for reduced efficiency and interrupted production, with notifications sent via email or SMS according to the type of alarm. Anti-theft monitoring can also be added to the Smart String Box, notifying users as soon as a panel is removed.

Components and modules of the Smart String Box are fully compliant with UK and international photovoltaic electrical regulations.

Highest resolution FE-SEM!

Hitachi Launches World’s Highest Resolution FE-SEM

The new SU9000 Field Emission  (FE) Scanning Electron Microscope (SEM) from Hitachi High-Technologies features novel electron optics which allow 0.4 nm resolution to be achieved at an accelerating voltage of 30 kV, with a usable magnification up to 3 Million times. This is believed to be the highest resolution-performance currently achievable on a commercially available instrument.

Featuring a new type of cold FE electron source with excellent stability and brightness and utilising Hitachi’s 25 year experience of in-lens detection technology, the SU9000 also provides outstanding ultra-low current and low voltage imaging of sensitive materials. This excellent all-round performance, combined with fast specimen exchange times and the optional scanning transmission (STEM) modes, makes the SU9000 the ideal choice for use in applications ranging from semiconductor devices, electronics, and advanced nanotechnology materials, to life sciences and medicine.

The new, cold FE electron source delivers probe current that is approximately double that of earlier models, giving high quality images with superior S/N and exceptional stability from the moment the electron beam is switched on. The high performance electron optics allow a resolution of 1.2 nm at an accelerating voltage of 1 kV to be achieved without the need for beam deceleration technology. This greatly simplifies low energy imaging and significantly increases sample throughput.

Hitachi’s unique dual through-the-lens detection system allows filtering of electrons of different energies, to give the capability for simultaneous multi-signal imaging. This provides extraordinary versatility for the imaging of structures and surface properties.

Using the scanning transmission (STEM) option, the SU9000 guarantees STEM resolution that can allow the lattice structure of graphite (C (002) d=0.34 nm) to be imaged at 30 kV accelerating voltage. The unique STEM detection system allows simultaneous bright field and dark field imaging and annular DF detection with selectable scattering angle. Up to 4 signals can be simultaneously displayed.
The SU9000 features side-entry sample insertion and can be ready for high resolution imaging in as little as 6 minutes or less; the fast exchange times benefiting from the high stability of the electron beam.

An order of magnitude better vacuum around the sample minimizes contamination, enhancing resolution and eliminating the need for an additional cold trap for cryo work on biological samples.

Ease of use is guaranteed through a new user interface, while a large 24.1-inch widescreen monitor offers a comfortable environment for both operating the instrument and viewing images.

Industrial cameras

3-CCD RGB Colour Cameras Now Available With GigE Vision

The JAI AT-140GE and AT-200GE 3-CCD cameras are available from Stemmer Imaging. Bringing the connectivity benefits of GigE Vision to 3-CCD technology, these new cameras feature a newly developed prism-block assembly to support the three CCDs. The AT-140GE and AT-200GE are ideal for a wide range of applications where colour is critical, including: print  inspection, paint  matching, medical  diagnostics, flat panel quality verification, semiconductor  production and food  sorting and have the performance and features to support a wide variety of machine vision applications.

The new dichroic prism block splits the incoming light into three distinct colour channels for precise RGB values and provides higher resolution and better light gathering ability than earlier 3CCD camera models. With precise sensor alignment (less than 1/4-pixel tolerance), this 3-CCD configuration offers better colour and spatial precision than single-CCD cameras which use Bayer filters and interpolation algorithms that give uncertainty for both edge positions and colour values. The cameras also contain a sophisticated linear colour matrix circuit which enables accurate colour space calibration with monitors, printers, and other peripherals.

The AT-140GE offers 1.4 Megapixel resolution (1392 x 1040) with 1⁄2” CCDs, while the AT-200GE provides 2 Megapixel resolution (1628 x 1236) based on three 1/1.8 inch CCDs. The new cameras operate at 20 frames per second (AT-140GE ) and 15 frames per second (AT-200GE ) at full resolution, with partial scan and binning modes available for even higher frame rates. A wide range of pre-set and programmable shutter and exposure modes are provided to support diverse application requirements.  Exposure can be controlled individually for each colour channel to enable colour balancing without noisy gain adjustments. 

A fully-compliant GigE Vision/GenICam interface lets users choose between 8- or 10-bit output per channel and provides the ability to transmit images up to 100m over industry-standard Ethernet cables. Software support includes a GigE Vision software development kit and Control Tool package.

    A solution for compact motor drive applications

    IPMs - a power electronics solution for application embedded motor drives, which is compact and has good thermal characteristics?

    Power electronics for application embedded motor drives need to be compact and to have good thermal characteristics. Different IPM (intelligent power module) concepts are competing with different sets of features to be the best solution.

    Higher integration and more complex subsystems are some of the current mega trends in power electronics.  Intelligent Power Modules (IPM) are very popular for motor drive applications. They are a combination of power semiconductors like IGBTs, MOSFETs and diodes with peripheral components like driver circuits. If a whole subsystem has a good match to an application, an IPM can bring a lot of unique benefits.

    In particular application integrated motor drives have very specific requirements: they need to be extremely compact, are often used in harsh environments and can have ten thousands of operating hours. Vincotech's flowIPM is dedicated to embedded motor drive applications and takes all typical requirements into consideration.

    What volcanic dust?

    Advanced borescopes employed to investigate effects of volcanic dust

    As volcanic dust once more creates havoc in Northern European airspace, controversy reigns over the levels of dust in which air travel is safe. As one of the measures to assess the effects of the ash, airlines and engine manufacturers are therefore looking to be able to assess the internal components of engines.

    Speaking in a BBC interview and clutching a vial of volcanic ash (to demonstrate the low levels involved), Willie Walsh (right) explained that a BA plane has flown though the 'red zone' for about 45 minutes at different altitudes. The aircraft then returned and video borescopes were employed to examine the engines and found no evidence of volcanic ash. (Item in BBC Radio news programme  25th May 2011)

    Alan Hasson from Ashtead Technology says "The latest video borescopes are ideal for this purpose, because they provide users with a comprehensive evaluation of the internal components of an engine, without having to dismantle it, which would be costly and time-consuming."

    Following the previous Icelandic volcano eruption in 2010, Ashtead Technology was contacted by an aviation maintenance firm looking to hire a high specification endoscope for emergency aircraft engine examinations.

    Avalon Aero, based at Biggin Hill Airport in Kent (GB), performed internal inspections of engines following flights in the ‘red zone’; an area in which ash might be encountered, but was deemed safe to fly by the Volcanic Ash Advisory Centre.

    Martin Darling, Avalon Aero’s Technical Director, explained: “Ashtead Technology’s engineers recommended hiring the Olympus IPLEX SAII Videoscope and the device proved extremely useful, providing quick and easy visual access to the internal components of aircraft engines. Our investigations did not find any ash within the engines and this evidence was of course extremely valuable to our clients.”

    Alan Hasson believes that aircraft engine inspection is a perfect example of the benefits of instrument rental: "The latest technology can be expensive to own, so instrument hire provides fast access to the best available equipment, which is especially useful when unforeseen situations occur," he says.

    Diesel flow measurement!

    Measuring flow rate, running time, fuel theft & more

    The rising cost of diesel means it is a valuable commodity for bulk commercial users across a variety of industries, making it vital to ensure that expensive fuel is used wisely, not wasted or pilfered. So the launch of the new multifunctional Fuel-View digital meter from Bronkhorst, which monitors flow rate and fuel consumption, engine operating times, diesel theft volumes and other parameters, should be of considerable interest to owners and operators of commercial vehicle fleets, construction plant, leisure boats, diesel-powered factory equipment, standby generators, heating boilers and diesel-fired burners.

    Their new Fuel-View series of flow meters, for fuel flows between 1 and 400 litres per hour, offers a compact, lightweight and cost-effective solution for measuring diesel consumption and operating times of road vehicles, tractors, construction plant, marine vessels, generators and all types of mobile and static engines, at competitive prices. The design’s unique features for preventing the theft of fuel, protecting against the overstatement of readings and any interference with compressed air, magnetic fields and disconnection, make Fuel-View one of the best multi-purpose instruments available on the market.

    The standard configuration is a ‘blind’ instrument, with integrated cable for the remote digital processing of signals. As an option, Fuel-View also comes with an on-board LCD readout, displaying such information as actual flow, total consumption and engine operating time in idling, overload and optimal modes. The instrumentation is either operated with an external power supply or, on LCD models, via an embedded standby battery, which provides autonomous running of the flow meter for up to 2 years.

    The Fuel-View series operates on the principle of a rotary piston, which is mounted in a chamber, and the rotating speed is measured by electronic sensors that record magnetic pulses, the number of pulses being proportional to the actual flow rate. This distinctive design allows mainstream fuel flow even if the measuring chamber becomes clogged up, although a filter does protect the chamber from contamination and can be removed and cleaned without dismantling the flow meter itself.

    Mounted in a strong, moulded zinc-aluminium alloy case, with full IP54 protection, the Fuel-View can be fitted in any position and withstands both vibration and hydraulic shock. There are a dozen different models with wired outputs, integral LCDs, or combinations of both, for various flow rates and engine power output. The smallest model, DFM-50, has a nominal flow rating of 25 litres per hour, with a minimum of 1 l/hr and a maximum of 50 l/h, for diesel engines up to 80kW (108 hp). The highest rating model, DFM-400, has a nominal flow rate of 200 l/hr (min 30 / max 400 l/hr), for engines over 300 kW (400 hp).

    “As a multifunctional system, the Fuel-View has many interesting commercial applications,” says Bronkhorst UK’s Managing Director, Andrew Mangell. “For engine design and testing, it will give instantaneous and totalised fuel flow rates, engine operating times and data on optimal running and overloads. Leisure boat owners will want to know about fuel consumption and any incidents of diesel theft, for billing purposes, as well as engine statistics for preventative maintenance. Engine overload times, fuel pilfering and possible engine interference statistics are also useful for construction plant and commercial vehicle operators. While hospitals and factories with standby diesel generators can tell whether the engines are running efficiently, when the next planned service is due and check that fuel isn’t being siphoned off or simply leaking away. Similarly, factory owners can gain valuable data about the carbon footprints of fork lifts and heating plant.”

    “These instruments are relatively inexpensive, easy to fit, extremely robust in use and will introduce a high level of management control over diesel fuel inventories,” he adds.

    Same day gearbox assy!

    Baldor (now part of ABB) has enhanced its fast turnaround gearbox assembly operation, which now has access to a large extensively-equipped machine shop, to the point where it can provide European customers with a same-day build service.

    Capable of building custom-configured power transmission products within hours of order placement, the new British-based assembly line can produce high efficiency gearboxes and gearmotors in a wide range of models and sizes from the renowned Dodge Quantis family. The Quantis product line is also directly interchangeable with most other leading gearmotor products for ease of replacement.

    According to Tristin Hurst, Product Manager for Baldor UK, "Custom gearbox assembly is a popular service with OEMs, end users, system integrators and system maintainers, but we have now raised the bar significantly. Any single-product order placed before 1pm will be available for collection or shipment that day - and the same applies to orders for multiple products placed before midday."

    Hurst adds: "We are also now able to offer a wider range of gearbox input and output options, helping customers configure the optimal solution, and to apply special paint finishes such as corrosion-resistant epoxy. Baldor's renowned high-efficiency motors also make the service ideal for customers who need to comply with forthcoming EU energy efficiency legislation stipulating IE2-rated gearmotors after June 2011 as well as NEMA Premium gearmotors for export to American markets."

    Dodge Quantis gearboxes and gearmotors are based on a modular design concept to facilitate the implementation of custom configurations. Baldor stocks all the components needed to assemble Dodge Quantis in-line helical (ILH) and right-angle helical bevel (RHB) speed reducers and gearmotors, in any case size from 38 to 108. The range includes the Quantis Gold gearmotor, which is based on an IE3 Premium Efficiency motor and is the most energy efficient package available in the industry.

    Quantis ILH series speed reducers offer a choice of foot or output flange mountings, are available in double or triple ratios, and have an efficiency of up to 98.5 percent per stage. The RHB series right-angle speed reducers offer shaft-mount, foot or output flange mounting, triple ratios, and have an efficiency of 98.5 percent per stage. They also offer two output options on the RHB units of the straight hollow bore, as well as patented twin-tapered bushings kits, which facilitate fast disassembly and reassembly by ensuring that the reducer will not seize onto the customer's driven shaft.

    Both the ILH and the RHB series are suitable for B5 flange mounted separate reducers which feature a universal clamp-collar design that enables users to employ the motor of their choice - when replacing a unit, they are not limited to any one manufacturer's products; they also offer integral gearmotors. The Quantis range employs spring-loaded nitrile rubber oil seals for better sealing - any gear reducer is only as good as the seal.

    Baldor's gearbox assembly service covers a wide range of IEC metric and NEMA models, to accommodate customers serving both the European and American markets. The company also offers a wide choice of DC and AC motors for its gearmotors; for the three-phase AC models it is also offering its latest IEC IE3-rated (former CEMEP 'EFF1+') motors, which provide unprecedented energy efficiency and are ideal counterparts to the high-efficiency Quantis product line.

    The use of IE2 rated (former CEMEP 'EFF1') motors becomes mandatory in the EU in June 2011 for a very wide range of common motor sizes. Baldor is actively encouraging OEMs to start considering early migration straight to the higher IE3 efficiency level, to help provide them with a competitive edge. Although IE3 is not due to come into effect in the EU until 2015, its USA equivalent, NEMA Premium, has been mandated since December 2010 by the USA's Energy Independence Security Act (EISA), which stipulates that virtually ALL 3-phase motors imported into the USA must exhibit this level of efficiency.

    Baldor's new build-to-order gearbox service operates on a 7 days a week basis. Customers can either collect their order direct from the assembly plant, or Baldor will arrange for shipment anywhere in Europe.

    New products to strengthen RF design & test

    In a second announcement National Instruments has announced that it has signed a definitive merger agreement under which they will acquire AWR Corporation (AWR).

    AWR is a leading supplier of electronic design automation (EDA) software for designing RF and high-frequency components and systems for the semiconductor, aerospace and defense, communications and test equipment industries. Upon the closing of the transaction, AWR will continue to operate as a wholly owned NI subsidiary under the leadership of the existing management team.

    The fast design cycles and increasing complexity of RF and wireless systems demand better integration between design and test. RF system designers need to validate their simulations with actual measurements, while RF test engineers need to increase test reuse and decrease test time through more design integration. By increasing the effectiveness of the integration between AWR design tools and NI software and hardware, NI and AWR together can significantly improve customer productivity through increased connectivity between design, validation and production test functions.

    “AWR has an exceptional team with strong RF talent and technologies that expand the NI platform into RF design, which is complementary to our capability to make measurements across the RF design flow,” said Dr. James Truchard, president, CEO and cofounder of National Instruments. “We believe this combination will accelerate the deployment of RF and wireless technologies and offers a significant benefit to the customers of both companies.”

    Both NI and AWR deliver unique strengths that together will enable customers to more productively design and test their RF systems. The acquisition will strengthen both companies’ core software brands, NI LabVIEW, AWR Microwave Office and Visual System Simulator, as well as the NI RF testing hardware platform. The full suite of AWR design tools in combination with a complete RF testing platform from NI will give customers a platform to decrease the time to market of their RF designs. NI will also augment its current academic and university RF and communications initiatives to include AWR software tools, so educators and students can benefit from the improved teaching and learning experience for the rapid design and prototyping of RF systems.

    “There is clear synergy between the customers and product offerings of both companies,” said Dane Collins, CEO of AWR. “NI has a leading platform in prototyping and testing of RF systems which is complementary to AWR’s RF circuit and system software design tools to the benefit of mutual customers. Together, we are better able to support and service our growing global installed base.”

    Eliminate control cabinets!

    Festo’s new CAFC protective valve terminal hood provides a highly cost-effective and elegant alternative to large and cumbersome control cabinets.
    Festo has dramatically reduced the cost of installing its valve terminals by launching a protective hood that can eliminate the need for a control cabinet in many applications. The new CAFC hood fits directly over the valve terminal and occupies minimal space, making it a highly cost-effective and elegant alternative to unnecessarily large and cumbersome cabinets.

    Most automation designers currently elect to house the system’s valve terminal and constituent control modules in some form of protective cabinet. However, conventional cabinets often take up far more space than is actually required by their functional content. By creating a small, self-contained protective hood for its valve terminals, Festo has overcome this problem. Fabricated from low cost aluminium and designed for minimal material usage, the hood can help system installers and machine builders save up to 50% of the space and 70% of the cost of a standard control cabinet.

    The CAFC hood is suitable for use with any Festo valve terminal, including the company’s highly popular CPX multifunctional automation platform. It provides a high degree of protection against the ingress of contaminants such as dust, water droplets, foreign particles, etc, as well as guarding against impact damage and helping to prevent anyone tampering with connections or settings. Typical applications include assembly and packaging machines, and process control systems.

    The hood is also ideal for automation designers seeking compliance with European ATEX directives stipulating that some form of protective cabinet must be used for switchgear and controllers located in potentially explosive work environments. The CAFC is suitable for use in ATEX Zone 2 and Zone 22 environments, which are defined as areas where combustible gas, vapours or dust are not normally present in the air, but if they do occur they might, for a short period, form a potentially explosive atmosphere.

    The CAFC comprises a hinged aluminium cover running the full length of the valve terminal, with retaining clips at either end of its bottom edge which accept socket-head securing screws. In its open state, the hood offers completely unrestricted access to the valve terminal’s electrical and pneumatic connections. Once closed, it has a visually unobtrusive appearance, with all pneumatic and electrical connections exiting neatly from a slot on the lower edge of the unit.

    A further advantage of dispensing with a control cabinet is that the valve terminal can be located very close to the process or machine that it is controlling, reducing tubing and cable lengths, improving the response time of pneumatic actuators and helping to minimise compressed air consumption.

    The hood is available with a numerous choice of lengths, to suit the customer’s particular valve terminal configuration. When ordered at the same time as a CPX valve terminal, Festo will ensure that the appropriate size of hood is shipped. Festo can also supply any configuration of CPX valve terminal and its associated hood as a complete ready-to-install solution, comprising both units pre-assembled on a backing plate.

    Watertight connectors for signal & control

    Marechal Electric has introduced watertight connectors to applications requiring signal and control contacts with the PNC series, which combine contacts for electrical power and control signals, in a single rugged housing. The multi-contact PNC connectors are sealed to IP66/IP67 as standard and feature corrosion-resistant butt contacts to ensure reliable operation, even in the presence of dust and contaminants.

    The integration of control signals and power into a single connector significantly reduces maintenance costs and down-time whilst increasing operator safety. Rather than disconnecting individual connectors for the power and for signaling and control functions, the operator can quickly and easily disconnect a single connector. This ensures that the machine is completely isolated and eliminates the risk of the operator disconnecting only one of the two individual connectors.

    Marachel will be showcasing the PNC series, and other connectors, on Stand C32, at IWEX 2011, NEC Birmingham, from 24-26 May.
    Their unique butt contact technology allows the connectors to provide an extended operational lifetime, even in high duty-cycle applications, with a rating of over 2000 load cycles. The compact size and the design make disconnection and reconnection quick and easy. A unique locking ring prevents accidental disconnection and maintains the connection to improve both reliability and safety.

    The PN plug is also available in a multicontact version with a different design: PN 7C connectors integrate up to 7 contacts, rated for currents of 25A per contact; whilst the PN 12C connectors offer up to 12 contacts, rated from 5 to 10A per contact. The connector housings are manufactured in a choice of glass reinforced polyester (GRP), which is rated for voltages up to 500 V a.c. and shocks to IK08; or in corrosion-resistant metal casings rated up to 415V a.c. and shocks to IK09. Both casings operate over temperatures from -40 °C to +60 °C. With a choice of wall-mounted socket configurations and a range of accessories, PNC connectors provide engineers with the flexibility to ensure quick installation and easy access in each location.

    Air-air heat exchangers!

    Rittal IP54 Air-Air Heat Exchangers offer low energy consumption

    Rittal air-air heat exchangers can lead to attractive cost savings over refrigerant based air conditioners due to their simple design, low energy consumption and minimum maintenance. Air-air heat exchangers utilise the ambient air to cool the air within the enclosure interior using only two working parts.

    Extracting heat from within the enclosure and releasing it into the surrounding environment the exchanger’s operation is based on the counterflow principle. Completely separate airflows are routed through the heat exchanger module by powerful fans which control the internal and external airflows. Thermal winding protection on the fan motors is provided as an added safety feature. The exchanger matrix, which is made of aluminium, is light and offers maximum durability.

    Units can be mounted internally or externally on the wall or roof of an enclosure. Spanning between 12 and 90W/K the range follows a similar platform design including appropriation to UL and is available ready for connection, along with wiring and cutout drawings. Sizes and cut-out dimensions match the TopTherm cooling unit generation which gives the exchangers the added adaptability of being interchangeable with TopTherm cooling units.

    Current transducers

    LEM has introduced the CTSR family of current transducers for use in a range of safety-critical applications including solar installations. Two transducers in the new series measure AC or DC leakage nominal currents, from values as small as 300 and 600 mARMS, with spectral components up to 9.5 kHz. The residual or leakage currents that the CTSR family is designed to measure can arise in fault conditions in a number of industrial or power-generation scenarios. Examples include solar panels that are coupled to an earthed grid, or in failure modes such as a short circuits or earth faults. The connection of a solar panel to the grid raises safety concerns; if a fault occurs there is a potentially serious safety issue around any human contact with the system.

    The CTSR family of transducers has been specifically designed to meet the latest safety standards that have been issued in respect of solar installations and inverters, namely VDE 0126-1-1, UL 1741, and IEC 60950-1. The devices are PCB mountable, lightweight (28g) components, with a 20.1 mm diameter aperture that easily accommodates multiple conductors. The residual-current capability measures the sum of all of the instantaneous currents flowing through the aperture, in single- or three-phase configurations. Conductors may be carrying primary currents of up to 30A/wire (AC or DC).

    The CTSR 0.3-P and CTSR 0.6-P safely measure nominal currents of 300 and 600 mA respectively, to a maximum accuracy of 1.9% and 1.5% respectively at +25°C ambient temperature, without offset, providing an analogue output to trigger a safety system in the event of a high leakage current. They both provide a high overload capability up to 3300A (for a pulse duration of 100µs, and with risetime of 500 A/µs), as well as a very high level of insulation between primary and measurement circuits, thanks to long creepage and clearance distances (11 mm), coupled with a CTI (comparative tracking index) of 600V.

    These products can also be supplied with a primary inserted conductor (made up of 4 individual conductors), and in that configuration have the designation “CTSR xxx-TP”.

    CTSR-series transducers operate from a +5VDC supply and have a typical current consumption of just 17.8 and 18.1 mA unipolar when measuring 300 and 600 mA respectively as nominal primary residual current (CTSR 0.3-P and CTSR 0.6-P models); They provide access to their internal reference voltage, and to options such as self test and demagnetisation.

    Models with higher nominal current range up to 3 ARMS to meet the needs of specific customers can be developed on request.

    As well as ensuring safety in solar inverter installations, LEM’s CTSR range is also ideal for a range of applications that includes symmetry fault detection in medium power inverters, failure detection in a range of power sources.

    The transducers are CE marked, conform to the EN 50178 standard and are recognised for industrial applications with an operating temperature range of -40 to +105°C. LEM offers a five-year warranty for each transducer.

    British gas storage automation contract

    System 800xA process control, safety systems, instrumentation and associated engineering for Storengy's new underground gas storage facility that will export gas to the National Grid

    Ancient map showing Stublach!
    ABB  has won a Main Automation and Instrumentation contract for a new natural gas storage facility in Cheshire (GB). The facility is designed to hold over 400 million cubic meters of gas, and will be controlled by ABB System 800xA along with ABB Instrumentation. The Stublach facility is being built for Storengy (a GDF Suez company) in Cheshire and will store gas in salt caverns deep underground. 

    The processing plant consists of gas compressors which move the gas between the caverns and the British National Grid Transmission System (NTS). Additionally, an on-site drying plant removes water from the gas before it is returned to the NTS. The site is expected to be in operation in excess of 25 years.

    Acting as the Main Instrumentation and Automation Contractor (MIAC), ABB will provide engineering design services for the Automation, Safety Instrumented System (SIS) along with the supply of an 800xA Integrated Process Control system and 800xA based SIS, ABB and third party instrumentation to Jacobs Engineering who are responsible for Engineering, Procurement and Construction of the plant. 

    The ABB system will control the import of gas into the caverns for storage and export of Gas into the National grid; this includes the complex control required to handle these transfers in both free flow and compression modes.

    Plant safety is critical and the TUV certified AC 800M HI controllers along with the field devices are used as the Safety Instrumented System to control the processing plant, associated pipelines and the well heads, which are situated up to 2 km from the processing plant.  This will be engineered by the ABB TUV certified engineers based in the UK.

    Availability and efficiency of the plant are crucial; the System 800xA controllers will be in a redundant configuration to ensure these key factors. The 800xA system also interfaces to fire and gas monitors around the plant, third party packages such as the compressor unit controls to monitor and control the plant. This provides integrated visibility for the operators of the process, plant assets along with the safety aspects for both the plant and personnel.

    A significant factor in the selection of the company for this project was ABB’s portfolio of automation, safety and instrumentation products along with the global success of the System 800xA, its Main Automation Contractor capabilities in Britain and the fact that ABB are just completing a similar installation for gas storage in Cheshire.

    The ABB System 800xA control system along with ABB Instrumentation provides inherent asset monitoring facilities to assist operators manage and maintain the plant to increase productivity and reduce energy usage.

    SCADA upgrade!

    Yokogawa Electric Corporation has released version R9.04 of the FAST/TOOLS web-based SCADA system. The product of more than 30 years of innovation in the oil & gas, petrochemical, and power industries, this platform-independent process management software is relied on by innovative industrial automation users worldwide and sets the standard for operational excellence.

    The FAST/TOOLS web-based SCADA system enables remote engineering and maintenance, and allows the deployment, and real-time management of process applications via secure web-based services, thereby increasing overall equipment efficiency (OEE) and return on assets (ROA).
    Remote plant management (RPM) is driving down operating costs and improving the sharing and exchange of information. With the proliferation of decision support and collaboration centres, data from a variety of sources can now be accessed and shared globally, allowing continuous application development and management. With this new version of Yokogawa's FAST/TOOLS SCADA system, a number of new functions are provided that make it easier to work with such services. By providing continual access to process and maintenance information from all sources, this will enhance efficiency by reducing cycle times and eliminating the need for the exchange of paper documents.

    Main features of the new system include operation recording and playback, E-mail notification and alarm reporting, advanced trending capabilities, and a FOUNDATION fieldbus faceplate library.
    With this new release, it is now possible to record HMI displays in real time. Functioning much like a flight recorder, this enables the synchronised playback of screens with alarms and events as well as process and trend data, and includes all mouse tracks and relevant keyboard strokes. The recorded video data can be used for cause-and-effect analysis, operator training, and simulation to increase overall safety, security, and regulatory compliance. This adds a significant new dimension to the capabilities of this software, which already includes audit trailing and diagnostics functions.

    In addition to its standard EEMUA 191 compliant alarm management functionality, this software now enables alarm notification messages to be e-mailed in real time to users who have subscribed to this service. This call-out function makes it easy to define when, where, and to whom notifications should be sent. The alarm management function now also enables the export of alarm & event notifications to programs such as MS-Excel for alarm analysis.

    The comprehensive trending capabilities of FAST/TOOLS have been extended with functionality that shows whether a signal is off-line. In addition, automatic and/or manual data backfill can now be used to display recovered data, allowing operators to confirm at a glance the integrity of the trended signals. X-Y plots have also been added to the rich trending library, allowing two-dimensional views of important process characteristics.

    The extensive faceplate and symbol library has been enhanced with FOUNDATION fieldbus faceplates that may be used together with Yokogawa's STARDOM (FCN/FCJ) autonomous controllers for increased flexibility in distributed applications. Faceplates are automatically assigned to the control logic based on the controller function blocks and are ready to use when deployed in the system environment. This allows for seamless integration of FOUNDATION fieldbus device messages and data, setting a new standard for operational excellence.

    Main target markets include oil and gas upstream/midstream, petrochemicals, chemicals, renewable energy, power, pulp and paper, pharmaceuticals, food, iron and steel, waste, and water and wastewater treatment, for applications such as remote process control, asset management, data collection, and storage in widely distributed applications.
