Story

One of the smallest and most rugged instrument of its type, Megger’s new FRAX 150 sweep frequency response analyzer (SFRA) is a powerful tool for revealing potential electrical and mechanical problems in power transformers, many of which are difficult or impossible to detect using other methods.

• Light weight
• Easy to use
• Easy to carry
• All in one box solution

Built-in computer

The instrument is completely self-contained, with an integral PC that has a high-resolution colour screen featuring a powerful backlight that makes it easy to read even in direct sunlight. It also has an internal rechargeable battery, allowing it to be used in locations where no mains supply is available.

Reveals wide range of transformer faults

Meeting all international standards for SFRA measurements, this innovative instrument offers a larger dynamic range and better accuracy than any other comparable test set currently available. In addition, for the test connections to the transformer, it makes use of special cabling technology that ensures repeatability of results.

The FRAX 150 operates by applying a sweep frequency test signal to the transformer and monitoring its response. The result is a unique fingerprint which, when compared with a reference fingerprint for the same transformer, reveals a wide range of faults. These include winding deformations and displacements, shorted and open windings, loose and broken clamping structures, core connection problems, core movement and hoop buckling.

Highest dynamic range and accuracy

Megger’s FRAX 150 incorporates powerful analysis and decision support software. In addition to offering the traditional magnitude versus frequency/phase display, this software also allows users to present data in an impedance or admittance versus frequency view, which is a powerful analytical tool for many types of transformer.

The test frequency range covered by the FRAX 150 is 0.1 Hz to 25 MHz, and users can set the range employed for individual tests to match the needs of the application. By default, the number of test points used for each frequency sweep is 1,046, but users can choose to extend this up to a maximum of 32,000. Typical measurement time is 64 seconds, but a fast mode is available that is capable of delivering results in just 37 seconds.

Ready to go

Small and easy to carry, with an operating temperature range of -20°C to +50°C, the Megger FRAX 150 sweep frequency response analyzer is ideal for use in the field. It is supplied complete with ground cable, four 3 m braid sets, two C clamps, an 18 m generator cable, an 18 m test cable, user manual and Windows software.

Harlequin has launched a brand new range of high spec security features, some of which are available as standard on Advance Bunded Oil Tanks and Fuel Stations, and as extra cost options on all other models.

At a time when tank security is a top priority for domestic, agricultural, industrial and commercial tank owners across the board, Harlequin has developed the safest, most secure tank options on the market.

Harlequin Advance Bunded Oil Tanks and Fuel Stations now come complete with a revolutionary Spinsecure Lock. The lock acts as a security device on the tanks' manhole or door access points. Once secured with its magnetic key, the lock will spin freely – meaning it is virtually impossible to force open or disturb.

As a further security option, customers can also choose to incorporate the brand new Yale Alarm Lock* as a means of securing the lockable fill and inspection points on the inside of the tank. The Yale Alarm Lock uses an armed cable to secure these points and sounds a 100db alarm in the event of the cable being attacked. A motion sensor can also be activated, making the tank owner aware of any changes in movement.

All of the latest additions to Harlequin's range of security features are currently available to order. For models which do not incorporate the Spinsecure Lock as standard, a Security Pack will be available as an extra cost option and will include both the Spinsecure Lock and the Yale Alarm Lock.

With Harlequin's latest innovations in tank security, protecting your tank contents has never been more easy. Providing customers with the benefits of Spinsecure's visual deterrent features, in addition to the added value of ensuring that any intruder will be stopped in their tracks by the Yale Lock's piercing alarm, means that your oil and fuel will never be safer than when stored in a Harlequin tank.

Pancras Church in Lewes, built in 1939, is of traditional period style with stone quoining and dressing around windows and doors. In order to accommodate new community facilities, BBM Architects proposed that a new annexe should be of contemporary design using a curved VMZINC standing seam roof. Use of pre-weathered QUARTZ-ZINC® has provided the most visually dynamic element of the scheme, replacing the former hipped, plain tile roof. The existing Sacristy floor was dug out to accommodate two community halls, one on top of the other. The upper hall has a gently sloping ceiling which follows the wave-lift form of the roof while to the south a new entrance hall or ‘Narthex’ with lift facilities has a roof form which echoes that of the former Sacristy. By using QUARTZ-ZINC, colour consistency will be retained while a natural, self-protecting patina which requires virtually no maintenance will continue to develop for decades to come.

The UK’s number one underfloor heating specialist has introduced a range of air to water heat pumps for the first time, as it looks to broaden its domestic heating solutions.

Uponor has entered the heat pump market after identifying a high demand for the energy efficient product, which is seen as an ideal accompaniment to its existing underfloor heating and plumbing systems.

Uponor is working alongside Toshiba Carrier to offer complete system solutions,, which are expected to significantly penetrate a market growth of around 100,000 units per year over the next 10 years.

It is hoped that the partnership will lead to a seamless heating provision from Uponor, both from an installation and aftersales perspective.

Uponor’s applications manager Neil Young said discussions had been taking place for around 12 months to add heat pump systems to the brand’s portfolio.

He said: “Uponor has always placed a huge emphasis on its ‘family of products‘ which offer a variety of different solutions and a number of advantages over our competitors.

“Our portfolio of heat pumps are a welcome addition and represent the start of an exciting new chapter for Uponor.

“Heat pumps and underfloor heating systems have always been very closely aligned, operating most efficiently at very similar low water temperatures.

“The decision to expand into this market will offer installers a fully integrated system and a peace of mind for the end user.”

Neil added that while there was a lot of competition in the heat pump market, Uponor’s ‘philosophy of plumbing’ would ensure lasting success for the business.

“A lot of companies sell heat pumps. What we want to do is to look at each individual project and offer more in terms of the finished solution. We will assess each project individually and see what is the best way forward. If heat pumps are suitable we can specify the right one together with the most appropriate underfloor heating package.

“If heat pumps are not a suitable option, then we will be able to say why not and find a solution that works.”

All Uponor staff will be fully trained at the company’s Lutterworth based training academy with representatives from Toshiba Carrier.

Each product will also boast a three year guarantee as standard, which to our knowledge is the longest agreement of its kind in the market.

Neil said that the Government’s Renewable Heat Incentive was also great news for the industry and could not be underestimated.

“Last year, figures revealed around 4,000 heat pump sales – a figure that will grow considerably over the coming years.

“With the Government’s commitment to its Renewable Heat Incentive as well, we see air source heat pumps as a significant addition to our range of domestic heating solutions.”

The Vaisala CARBOCAP® Carbon Dioxide and Temperature Transmitter GMW116 is a compact wall-mounted transmitter that helps save energy by providing accurate carbon dioxide measurement in demand-controlled ventilation. The transmitter incorporates Vaisala’s innovative silicon-based CARBOCAP ® technology for excellent long-term measurement stability.

The GMW116 enables efficient and economical ventilation control by using actual carbon dioxide measurements – rather than assumed fresh air requirement based on the number of people in a space – to determine ventilation demand. This improves the accuracy of ventilation control, resulting in improved air quality and lower energy consumption.

CARBOCAP ® technology enables excellent long-term accuracy and eliminates the need for self-calibration by using alternating dual wavelengths – one to measure CO2 and a second reference wavelength. Because the GMW116 also measures temperature, there is no need for separate temperature compensation in CO2 measurement.

Because it requires no self-calibration, the GMW116 can be used in all types of occupied spaces. It’s ideal for spaces that are occupied around the clock, such as hospitals, residential buildings, and homes for the elderly. The transmitter’s excellent temperature tolerance means it is also suitable for refrigeration applications.

The GMW116 is easy to install thanks to its simple two-piece construction: just complete the wiring to the terminal block on the bottom of the unit, then snap on the lid of the electronics enclosure to complete the installation. This quick and simple process means that the electronics are not subjected to the dusty conditions often present during the early phases of a building project.

The new design, in signal white (RAL9003) color, blends in well on most modern office walls. The GMW116’s enclosure is made of UL V0-approved materials and is IP30 protected. The transmitter is compatible with European, US, and Japanese junction boxes, and is covered by a two-year warranty.
