The NHBC’s decision that vapour permeable underlays require supporting high level ventilation illustrated the extent to which condensation in the roofspace has become a problem. Roof ventilation specialist Klober’s ‘Condensation Risk Analysis’ service has therefore become a highly valuable resource as specifiers design ever more airtight buildings. The drive towards thermally efficient construction has made the need for balanced roof ventilation more important than ever as Klober Technical Manager Graham Copson commented “Demand for such information has grown with increased use of ‘non-ventilated’ systems and despite the NHBC ruling the need to assess potential condensation risk is no less critical. Heavy levels of vapour are being created in short periods after which homes are often left unheated for long periods. If ceilings are not adequately sealed moisture carried by warm air is certain to condense”.

Story

When Kent’s Elite Fire Safety Ltd (EFS) were faced with providing fire protection for Charlesville Mansions, a million pound apartment block in a charming red brick mansion within the sought-after conservation area of Barons Court near to Fulham and Kensington High Street, they knew that their selection of fire alarm was critical because damage to the Victorian fabric of the building caused by chasing out precious plasterwork to install wires and cables should be avoided. EFS had worked with Detectomat’s SRC 3000, a radio-linked, wireless solution system, in which each unit transmits data by radio frequency to a receiver before. They knew that it offered the considerable advantages of being wire free, which not only include avoiding damage to historic walls and ceilings but also cost. Because installation is so fast, labour charges are kept to a minimum and there is very little noise and disruption, another important factor in this sought after residential area.

Douglas and Gordon, an up market London estate agent, block and property Management Company, instructed EFS to install independent wireless fire alarms into each of the 5 separate entrances knowing that they would respect the nature and quality of the building.

EFS are based in Kent to provide fire protection for many types of businesses throughout Kent and London including offices, warehouses, schools, manufacturing plants, listed buildings, private residential, private commercial, retail, care homes, local authority premises, hotels and many others.

Sophia Scott, Douglas and Gordon’s Property Manager commented, “Elite Fire Safety carried out their works swiftly and kept disruption for the residents to a minimum. The Detectomat wireless system is much smaller and more discreet than others I have seen and does not detract from the look of the building, I would not hesitate in using Elite or Detectomat’s SRC 3000 again.”

Detectomat’s products offer ranges from design conscious detector covers for residential and commercial applications to conventional, addressable and leading edge wire-free systems, marketed under the company’s “Wireless detect” brand.

While capable of delivering 900 A continuously and 5,000 A for short periods, the new Ingvar primary current injection test set from Megger is readily portable, making it ideal for on-site use, even in applications such as underground substations where access would be difficult or impossible for larger test sets. The design has also been optimised to minimise in-rush current, thereby making Ingvar suitable for use on supply systems with limited capacity

• 2 parts each weighing less than 20 kg
• Great commissioning tool as it can deliver 500 A continuously and 5000 A for a short period
• Unique I/30 function to check test set up
• Full range of accessories

500 A from 2 units of less than 20 kg

Ingvar consists of a power module and a separate control module. The modules are housed in robust carrying cases, each of which weighs only around 20 kg. In addition to enhancing portability, this two-module arrangement also has the benefit of allowing the power module to be positioned close to the equipment under test, thereby reducing the length of test leads needed, while the control module is positioned for ease of access.

Typical applications include primary injection relay testing; circuit breaker testing up to 500 A nominal current and 5,000 A instantaneous current; checking phase, polarity and phase angle of current transformers; heat runs; testing grounding systems; and evaluating the performance of automatic reclosers and sectionalisers.

Unique I/30 function for setting up tests

The Ingvar test set is fast and easy to use. Interconnecting the control and power modules takes less than a minute, and the clearly marked control panel is divided into sections as an aid to rapid set up. Predefined settings are incorporated for commonly encountered applications, and any test can be repeated by pressing a single button. A unique I/30 function allows setting up to be carried out at greatly reduced current, thereby eliminating unwanted heating of the test sample, which can lead to erroneous results.

A large easy-to-read display is provided that shows current and time, with timing accuracy ensured by the use of automatic zero-crossing switching. The test set can also calculate and display other quantities, including current transformer turns ratio, impedance, resistance, power, power factor, and phase angle. Current and voltage can optionally be presented as percentages of the nominal value, and a second display channel is available to show an additional voltage or current.

Full range of accessories

A further aid to convenience and accuracy is the fast acting hold function that freezes readings on the display when a signal is received by the stop input, when the equipment under test interrupts the test current, or when current injection is stopped by other means.

Megger’s new Ingvar primary current injection test set is supplied complete with a 3 m cable to interconnect the power and control modules, a 2 m current cable and a 5 m grounding cable. Optional accessories available for use with Ingvar test sets include interconnection extension cables up to 10 m in length, high current probes for testing MCCBs in situ, a current transformer switchbox, and a range of multi-cable high-current test leads.

ELGA Process Water introduces fast water system monitoring tool.

ELGA Process Water has introduced a new monitoring tool to help in microbiological control of water systems. Bactiquant®-water is a simple to operate test system that gives a rapid indication of total viable bacteria count – a test which normally takes two or three days – in under an hour. This means that system performance can be monitored on a day-to-day basis, and any deviations from normal conditions can be detected early.

Bacteria from a measured sample volume of water are concentrated by a membrane filter. A fluorescent labelled enzyme substrate is added and the filter unit is incubated for 10-30 minutes allowing bacterial enzymes to react with the substrate to form a fluorescent product. The number of bacteria is estimated by measuring the amount of fluorescence using a hand held fluorometer. The signal produced is directly proportional to the amount of bacteria present, and scientific studies have documented good correlations between Bactiquant®-water and conventional plate counts and microscopic methods.

The Bactiquant®-water package includes sampling equipment, membrane filter, enzyme substrate and fluorometer. It also comes with its own FDA compatible database software which establishes a baseline for normal operation and, using Statistical Process Control based on ISO 11462-1, generates “normal”, “alarm” and “action level” signals. And, of course, ELGA Process Water provides full on-site operator training.

Bactiquant®-water puts water in your control rather than expending resources in detecting and correcting microbiological problems after they have occurred.

At this year’s high-profile Electrical Industry Awards, Megger’s new MFT1700 range of multifunction installation testers scooped the coveted award for Innovative Test and Measurement Product of the Year. The testers were chosen from a wide range of entries in this hotly contested category by a panel of independent judges, all of whom have in-depth knowledge of the electrical industry and its requirements.

Highly intuitive

Among the many benefits that helped to propel the MFT1700 testers to success in the awards are their ease and speed of use. All functions are clearly shown on the front panel and the operation of the instruments – including test selection and the connection of leads – is highly intuitive.

The digital display is complemented by an analogue arc, which allows many types of tests to be carried out more quickly and conveniently. The display also has two digital readouts. The primary readout shows the main parameter under test while the secondary display shows additional information, such as the test voltage or current.

Innovation switching

Innovation is also found in the earth loop impedance testing function. Unlike traditional multifunction testers, the new instruments support two-wire testing, which simplifies connection and makes testing possible at points like light switches where no neutral is available. The instruments offer both non-tripping tests for RCD-protected circuits, and high-current tests for circuits without RCD protection.

A further time saving innovation is automatic switching between connection terminals, which means that when loop tests are carried out with a mains plug, it is unnecessary to change connections during the test.

Increased capability

For RCD testing, the new instruments can be used with type A, AC and S RCDs. There is an option that tests type B, pure D.C. RDCs used on some PV systems. In addition to the standard ramp test, a new pass/fail ramp test has been introduced which saves time in applications where it is only necessary to show that the RCD trips between preset maximum and minimum limits.

An innovation that significantly increases the versatility of high-end instruments in the MFT1700 range is the incorporation of facilities for earth electrode testing. The high-end models also have facilities for testing three-phase RCDs and checking phase rotation. In addition, they are provided with rechargeable batteries that save money and ensure that users are never caught out by having no suitable batteries to hand.

Even safer

Safety has been given particular attention, and the instruments have a CAT IV 300 V rating in line with IEC 61010. In addition, built-in protection means that accidentally connecting an MFT1700 to a live circuit when carrying out an insulation or continuity check generates a warning but does not damage the instrument, even if the test has already been initiated.

Finally, the MFT1700 range includes models that have facilities for storing results for download via a wireless Bluetooth link to a PC, PDA or Smartphone running Megger’s PowerSuite software.
