Abloy UK has launched its new electro-mechanical locking solution Cliq Remote to the power sector, helping to make key management easier across large, multi-site masterkey applications.
Named Access Control Product of the Year at the IFSEC Awards 2011, Cliq Remote uses web-based software allowing power engineers and their contractors to have keys remotely authorized for use in specific operational areas within the existing masterkey system for a pre-determined period of time. This ensures a high level of key control incorporating maximum flexibility to ensure access in the event of an emergency to nominated key holders. Cliq Remote provides comprehensive audit trails and the ability to remove lost or stolen Cliq Remote keys from the system, thereby providing tight key management at all times.
For the power industry, padlocks are likely to be an integral part of security and the Cliq Remote variant carries an IP57 water rating as well as conforming to BS EN 1303 like the rest of the range.
Cliq Remote operates from a key receiving access rights and/or time validations through a wall programming unit or a personal programming unit connected to a mobile phone that can transfer authorizations for user keys.
Cliq Remote offers a cost-effective extension to existing systems while providing for centralized administration, key management automation and an automated audit trail, with timely reporting on systems statistics.
Due to the use of individually programmable cylinders and keys, Cliq Remote enables complete electronic security management and control, even to grant variable access rights for personnel visiting remote, secure locations.
Barry Jenkins, Abloy UK general sales manager for market development, said: “Cliq Remote offers the power sector previously unattainable functionality for remote access control. Not only is it easy to install and to use, but keys can also be managed remotely across multiple sites for timed access and keys that get lost can easily have their access rights removed without changing cylinders.
“Further demonstrating Abloy UK’s commitment to providing quality access control solutions across all utilities, Cliq Remote means less person to person contacts for key updates, less administration and fewer software installations,” he said.

Units are rugged to 5000 g pk shock and powered by a 20-30 VDC or 2-18 mA constant current supply. The accelerometer is immune to parasitic coupling when used with shielded Kistler cables.
A bolt tension solution that can replace torque
The industry has recently recognized the importance of the tension of fasteners and this will challenge some of the torque tightening practices that exists today as the industry matures and adopts more sophisticated technology to both improve reliability and reduce maintenance costs, thus improving the economies of electricity production from wind turbines. Bolts can be installed in one of two ways: by torque tightening or by hydraulic tension tightening.
Torque is the rotational force applied to a lever, multiplied by its distance from the centre of the tightening end (fulcrum). The force is measured in Nm or lbs/ft. Torque tightening rotates the bolt head or nut to tighten and stretch the bolt to clamp two surfaces together. Hydraulic torque wrenches allow the operator to control the torque applied and are used extensively to tighten wind turbine bolting.
It is simple to use, however, this technique suffers from inaccuracy due to inconsistent friction. Even on lubricated threads and nuts, the level of friction is uncontrollable. This means there is a lack of tension control that can lead to bolt failure, and ultimately, joint integrity being compromised.
Hydraulic tension tightening is also used to tighten (large diameter bolts on) wind turbine boltings. The tightener pulls the bolt axially by means of a hydraulic piston. When the bolt is stretched by a specified amount, the nut inside the tensioner becomes raised off the flange creating a gap between the flange faces. The gap is closed by tightening the nut and when the hydraulic pressure is released, the tension is transferred to the bolt and the flange.
During this process tension loss occurs (“load transfer relaxation”). To compensate for this loss, the hydraulic pressure originally applied is increased (“hydraulic overload value”). However, the amount of load transfer relaxation cannot accurately be predicted and varies from one bolt to another. Hydraulic tensioners are therefore unable to control, or measure the tension, that has been achieved for each bolt and also unable to provide an in-service reliability check.
Innovative engineering has come up with a bolt that indicates when the specified load/tension has been achieved during tightening. James Walker RotaBolt developed the RotaBoltà‚® system to provide a simple and effective measure of the real load/tension in a bolt. The RotaBoltà‚® can be used in either torque or tension tightening. When a RotaBoltà‚® is tightened, the cap locks at exactly the right amount of preload in the bolt.
This allows for more control during tightening while at the same time ensuring that the customer’s design criteria are met independently of the tightening system.
It also enables bolt reliability status to be instantly checked in service; something the traditional bolt retightening checks are unable to do.
Cortec’s air powered technology eliminates hazardous propellants
As restrictions and regulations tighten on the use of aerosol products, Cortecà‚® Corporation offers an effective alternative to hazardous hydrocarbon-based aerosols.
Cortec’s EcoAirà‚® products are water-based, and powered by compressed air as opposed to traditional chemical propellants; eliminating hazardous chemical delivery systems and preserving your health and the environment.
The products are contained in a Mylar pouch, which is called EcoPouchà¢â€ž¢, inside a fully recyclable aluminum container.
This type of powered spray affords several significant advantages over traditional aerosol sprays.
EcoAirà‚® has no innate harmful, hazardous, or polluting characteristics, is non-flammable, and enables the use of products rated for their biodegradability and nonpolluting characteristics. In old spray systems, the chemical used was altered by the propellant carrier.
This disallowed the use of many biodegradable and water based formulations. EcoAirà‚® spray technology lets the chemical formulation remain in pure form without being mixed, thereby guaranteeing that the product you are spraying works exactly how it should.
Since EcoAirà‚® products are powered by compressed air, they are much less volatile and can be used instead of aerosols particularly where shipping, storage, and application restrictions apply.
In addition to being non-flammable, Cortec’s EcoAirà‚® products are biodegradable, environmentally friendly, minimize waste disposal, and safe to use.
Gear heat treatment for toughening up your teeth
According to experts, heat treatment is a core competency that represents around 30 per cent of typical gear manufacturing overheads, so selecting the right heating and quenching process is vitally important for durability, reliability, cost control and the avoidance of over-engineering. Keighley Laboratories of West Yorkshire, which offers advanced analysis, testing and heat treatment of metals on a single site, provides a range of case hardening, induction hardening, Tufftride ferritic nitrocarburizing and other processes for high performance gears and believe it can assist customers by engineering out cost and engineering in performance.
Case hardening generally and carburizing and carbonitriding in particular are commonly used for high performance gears, producing a softer, tougher core to avoid tooth breakage, while achieving a hard wear-resistant case to prevent pitting. It lends itself to both high and low volume requirements and a wide variety of gear shapes and sizes, up to around 1 meter in diameter and 2 tonnes in weight at the Keighley Labs facility. Case depths between 0.1mm and 5mm are achievable, with PLCs and oxygen probes enabling temperatures and cycle times to be accurately controlled.
For larger gears up to 3.5 meters in diameter and 4 tonnes in weight, or where deeper hardening to 10mm is required, Keighley Labs offers induction hardening, which uses high, medium or low frequency alternating current to heat the surface of a gear tooth. Both spin hardening and tooth-by-tooth or contour induction hardening methods are available, with the tooth-by-tooth techniques especially suitable for larger gear wheels. Spin hardening is usually a rapid process, often completed in a matter of minutes, whereas tooth-by-tooth, also known as progressive or zone hardening, is more time consuming, although both methods ensure low distortion.
For fragile gear geometries, Tufftride ferritic nitrocarburizing is a further option. A comparatively low temperature, low distortion salt bath process, it produces a thin, iron nitride compound layer that is particularly resistant to wear and prized for its excellent sliding and running properties, ideal for gear wheels. Other specialist heat treatment techniques are available, as well as pre- and post-hardening processes such as annealing, normalizinga and stress relieving.
Internationally certificated for all heat treatment processes, with the options of metallurgical inspection by its UKAS accredited in-house testing service, Keighley Laboratories has experience of processing gears of all types and all sizes from several millimeters to several meters, although most fall in the mid-range sizes for mainstream power transmission applications.

GE acquires Commtest and enhances condition monitoring
GE has announced the acquisition of Commtest, a provider and designer of machinery health information systems. GE Energy’s Bently Nevada product line, a global leader in condition monitoring, will incorporate Commtest products into its portfolio and enhance an already robust lineup. Bently Nevada provides machinery protection and condition monitoring for refineries, petrochemical plants, power plants and wind farms.
Over 50 years, Bently Nevada has built a reputation for improving the reliability and performance of critical production assets like turbines, compressors, motors and generators.
As a major component of predictive maintenance, condition monitoring is essential to increase asset longevity. Through condition monitoring, plant managers constantly receive data that provides input about the health of machinery. For example, by knowing the vibration behavior and temperature of certain assets, managers can make strategic decisions about preventative maintenance to avoid asset fatigue and failure. This is especially critical in the oil and gas and power industries where failed assets can cost hundreds of thousands of dollars a day in lost production revenue.
New Ocean Optics measurement system for quality inspection of solar simulators
Ocean Optics, specialist in miniature photonics, will unveil at the PV SEC exhibition in Hamburg a new optical measurement system for absolute irradiance measurements of solar simulators and other radiant sources. The RaySphere allows you to measure absolute irradiance over different spectral ranges from the UV to the NIR (380-1700 nm).
The portable RaySphere is especially useful to solar simulator manufacturers and R&D labs as a tool to validate the output of installed solar flash lamps. The flash of a solar simulator is used within the photovoltaic (PV) manufacturing process for the binning of cells according to spectral response and for final PV module efficiency measurements. For the verification of such solar flashers Ocean Optics developed RaySphere ” a system that provides the necessary accuracy and resolution to measure and analyze the performance and stability of the flasher, with advanced, ultra-low jitter triggering electronics for timing the measurement to the flashes. The calibration of the RaySphere has been validated by an accredited certification lab to ensure accurate detection, allowing you to evaluate and qualify the spectral distribution of your solar flashers and simulators according to the IEC60904-9 (2007) norm.
The RaySphere includes two thermo-electrically cooled detectors allowing highly repeatable and accurate spectral analysis of solar flashers from 380 to 1700 nm. A second version contains a single thermo-electrically cooled detector for measurement to 1100 nm.
The system also includes advanced, high-speed electronics and an intuitive and powerful software interface. Extremely brief measurement times enable the detection of a complete spectrum during a flash or even during a portion of the flash. In addition, the measurement can be triggered by a fast response photodiode that reacts on the increasing intensity of the flashlight with sub-microsecond response times.

Robust couplings make power stations fit for varying net capacity utilization
For more than 40 years, Voith has been producing special variable-speed couplings for boiler feed pumps of cogeneration plants. The long service life and the reliability of the couplings reduce failure and standstill risks and therefore contribute to the availability of the power stations. In 2010, the 800th coupling of this type was sold to the OMV power plant Burghausen (Germany).
Gas and steam power plants can be constructed at relatively low cost, and they have significantly lower emissions than coal-fired power stations. They are also suitable for load following operation. This means that their output can be adjusted at any time in line with peak loads or during periods when there is a surplus of electricity. This feature is important, especially when supply gaps – which may well occur as a result of a new energy mix – have to be evened out.
One of the most recent gas and steam plants fitted with a Voith 562 SVTL 12.1 variable-speed turbo coupling is the 400 MW power station in Timelkam, Austria, Voith Turbo with an efficiency of nearly 60 percent. It produces up to 2450 GWh of power every year and can supply nearly 700 000 households.
As a result of the envisaged move towards more regenerative energy, Voith anticipates a rise in demand for the couplings that were designed specifically for the boiler feed pumps in combined cycle power stations. For optimized plant performance, Voith has developed couplings for higher pump outputs (4 to 6 MW).
A sealing solution to reduce maintenance costs
Wind power can supply large amounts of clean electricity at a sensible cost; however, there remains an acute need to iron out the hurdles the industry still faces. Few turbines reach the end of their life cycle without repairs, as such, operators need to anticipate problems to minimize costs. One way of preventing such problems arising is to use turbine components that are reliable, efficient and cost effective.
Small components, such as seals, are often overlooked to an OEM’s detriment. Ineffective seals in wind turbines fail to adequately protect the bearing. Lubricant leakages not only cause blade staining and cleaning to be required, but leakages inside the turbine can cause components to fail. Inadequate seals allowing the ingress of particles into the bearing compromises performance and accelerates equipment failure.
Seal manufacturing specialists have developed designs to provide solutions to the problem. James Walker has a number of on-site joining solutions, such as the Walkerseleà‚® OSJ-2, that offer the same integrity, life and performance as the seal fitted during manufacture by an OEM.
Effective on-site joined sealing technology can be used on many of the bearings on a wind turbine and timely seal replacement reduces lubricant loss whilst maintaining low friction to extend component life and improve reliability.
Auma’s fibre optic initiative advances actuation
Auma, the manufacturer and developer of modular electric actuators for the power industry, reports growth of fibre optics (FO) in process technology.
Expanding demand for this field data transfer solution has led to Auma’s introduction of a single-mode FO interface capable of supporting automation solutions, with a range of up to 15km between field devices.
Confirmed FO benefits include transmission over large distances.
Resistance to EMC ensures data and supply lines can be installed in one duct. Redundant data transmission is achieved by simple loop topology; galvanic isolation is integrated virtually and overvoltage damage is prevented.
These advantages led Auma to equip its actuators with integral FO fieldbus interfaces in the late 1990s.
Established multi-mode fibre optic technology supports distances up to 2.5km. Ongoing R&D from Auma has led to introduction of a single-mode interface version with extended functionality and simplified handling. The initiative introduces a flexibility that caters for substantially greater distances between field devices. An enlarged actuator terminal compartment simplifies cable connection and the new FO solution can be configured, as required.
A further confirmed benefit of fibre optic interfaces reported by Auma is evaluation of FO signal quality during operation.
Should the optical signal fall short of its required level, an alarm is transmitted to the DCS via fieldbus: appropriate measures can therefore be taken prior to system failure.
FO cable checks are integrated into the comprehensive self-monitoring capability of Auma’s new Generation .2 actuator controls.
Signals are transmitted to the control room in compliance with Auma or NAMUR classifications.
And, reflecting Auma’s development philosophy for all previous version products, actuators can be specified with the new FO interface either in line or with star / loop topology.
Reducing the risks of equipment failure
Advanced bolt tension technologies can reduce the risks of bolt failure by accurately measuring tension across bolted joints. James Walker’s RotaBoltà‚® offers accurate installation to within à‚±5 per cent of the customer’s specified design tension. This reduces the risk of bolts loosening in operation due to factors such as vibration or thermal cycling. Additionally, RotaBoltà‚® tension control fasteners allow any loss of tension across the bolt to be easily monitored by a simple tactile or visual check requiring no specialist expertise or tools. This technology can reduce the risks of equipment failure whilst also improving safety and dramatically reducing maintenance costs.
In addition, Sealing manufacturing specialists have developed on-site joining technology to fit the wind industry. The Walkerseleà‚® OSJ-2 is an on-site jointed seal concept from James Walker that offers the capability to replace a typical turbine main shaft seal in less than 30 minutes with no major disassembly.
“As the demand for energy grows, technology in the wind industry needs to improve equipment reliability”, said Keith Tripp, marketing director of James Walker. “Recent activity has largely focused upon maintaining the reliability of large components.
However, smaller components are also vitally important and should not be overlooked.”

Leak-free, plastic mag-drive pump range expanded
A new pump model DB5.5 has been added to the established range of Finish Thompson DB Series of Plastic Magnetic-Drive Sealless Centrifugal pumps. This new model DB pump covers flow rates up to 5mà‚³/hr and differential heads to 6.5 meters and is designed and built to provide the important benefits of sealless, magnetic-drive pumping, such as optimum efficiency and reliability, even in the most corrosive and challenging environments.
Available from pumping specialists Michael Smith Engineers, DB5.5 pumps can be specified in polypropylene or PVDF and have extended dry-running capability. When specified with carbon bushing DB pumps can be dry-run for hours, so are less prone to operator error.
DB pumps offer high working pressure capability (up to 90psi) which means fluids with high specific gravity (over 1.8) can be pumped without the need for impeller trimming. They have a maximum operating temperature 180à‚ºF (82à‚ºC) for polypropylene and 220à‚ºF for PVDF.
High operating efficiency and low energy costs are key objectives for pump operators and DB pumps make an important contribution with operating efficiency up to 70 per cent.

Camfil Farr Power Systems takes air filtration to a new level
Inlet air filtration systems are essential for the operation of all turbomachinery.
They have evolved from simple coarse solid particulate removal systems, to complex removal systems that remove solid, as well as liquid particles.
As the demand for gas turbine thermal efficiency escalate; with firing temperatures increasing and machine tolerance decreasing, gas turbines become more sensitive to particles in the combustion air, thus requiring more efficient and reliable filtration equipment.
Also, the need for longer service intervals and higher output, is forcing operators to optimize their installation, in both a short and long-term perspective.
Camfil Farr Power Systems now presents the new Cam-Flo XMGT and the upgraded CamGT filters, both taking air filtration to a new level, by offering extra high class options also in the world of gas turbines.
Camfil Farr, industry expert in filtration technology, is releasing a brand new high-tech pre-filter, CamFlo-XMGT.
The filter is available in filter classes F6 to F9 (EN779:2002/2011), and is specially developed for the demanding turbomachinery market. One of the XMGTà‚´s most significant features is the exceptional ability to keep its efficiency over its entire lifetime, thanks to a unique synthetic media. The media has been developed for lowest possible energy consumption, with a very low initial pressure drop. The innovative design, with conical shaped bags seamed in a way that allows maximum air distribution through the media surface, makes it an excellent pre-filter choice in most surroundings.
Introduced more than a decade ago, found in a large number of gas turbine applications around the world, CamGT has become a trendsetter in the industry.
In order to meet increasing demands for performance and power output, the company has now upgraded the CamGT with a new improved filter media and reinforced polypropylene frame.
ts robust heavy duty design, combined with high efficiency and low pressure drop, guarantees optimum protection and engine performance under the most demanding operating conditions.
The upgraded design also optimizes filter geometry, reducing initial pressure drop.
The patented construction also features vertical pleats with hot melt separators, allowing trapped water to drain from the filter during operation. This reduces the risk of dissolved impurities to re-enter the filter and pressure drop is maintained low in high humidity conditions.
Tektronix TPS2000 series updated to improve viewability
The Tektronix TPS2000 series of power analysis oscilloscopes has been updated to improve the viewability of the screen in field-based applications.
The new TPS2000B series incorporates a brighter and higher-contrast screen which strongly improves the viewing experience in difficult lighting conditions or when viewing the screen from an acute angle, says supplier TTid.
The TPS2000B differs from conventional oscilloscopes in having four fully isolated channels, making it uniquely suitable for measurements on multi-phase power installations. Using P5120 passive high-voltage probes, floating and differential measurements up to 600 V RMS Cat II can be made.
As well as mains operation, the oscilloscopes can be operated from their built-in “hot swappable” batteries, which provide up to eight hours of continuous operation, making them ideally suited to field-based measurements, according to TTid.
Standard FFT analysis can be used to reveal signal interference, crosstalk and other effects visible only in the frequency domain. Optional power analysis software provides harmonics analysis, instantaneous power waveform analysis, switching loss, phase angles, and dv/dt and di/dt cursors.
The TPS2000B series is available in three versions with bandwidths up to 200 MHz and real-time sampling rates up to 2 GS/s.

“We expect that further work with this automation company will help us upgrade our generating capacities and improve process safety, reliability and operating efficiency,” said Rahmetulla Alzhanov, chief engineer and deputy chairman of RusHydro’s management board.
Alexey Etkin, head of Emerson Process Management’s systems solutions in CIS and Turkey, said, “The memorandum gives us the opportunity not only to respond to requests from RusHydro for technical solutions, but also to actively participate in the development of technical strategy based on innovative process automation solutions for power facilities.”
Large-scale energy storage technologies to capitalize on renewables
All Western European countries are aiming to boost the contribution of renewable energy, which is set to create huge market opportunities for energy storage.
New analysis in Frost & Sullivan’s European Large Scale Energy Storage Market and Opportunities from Growth in Renewable Energy finds that the market earned revenues of $1249.1 million in 2010 and estimates this will almost double by 2017 up to $2 billion. The following technologies are covered in the research: pumped hydro energy storage, compressed air energy storage, hydrogen energy storage, battery energy storage and molten salt energy storage.
Escalating demand for energy, paralleled by technological advancements, widespread use of electric vehicles and widespread deployment of renewable energy are underlining the importance of large-scale energy storage technologies.
“Targets to increase contribution of renewable energy sources are encouraging the implementation of large scale energy storage technologies,” says Frost & Sullivan industry manager Suba Arunkumar. “Long-term plans to install smart grids and achieve complete automation are possible only if large-scale energy storage is implemented, as it will ensure regular power supply from renewable energy sources.”
As most of the energy storage technologies to enable the expansion of renewable energy in Europe are environment-friendly, renewable energy could be effectively stored without environmental hazards for a time frame ranging from a few seconds to several months.
“Smart energy management systems are also promoting the prospects of energy storage technologies,” adds Arunkumar.
“Smart energy systems include solutions such as demand-side management and smart grid solutions that offer reliable, high quality power, while effectively meeting spiralling energy demand.
“Smart energy management is likely to be difficult to achieve unless efficient energy storage systems are installed.”
