This is a common question that is answered often by our technical support department. The solution below applies to the Megger MFT1710, 1711, 1720, 1721, 1730, 1731 and 1735.

The word DUCTER was registered by Evershed & Vignoles in 1908 – a shortened version of ‘conductor tester’ that has since evolved into an adjective; similar to HOOVERing a floor or MEGGERing an electrical cable.

Evershed & Vignoles developed the original ‘Ducter’ and were one of the companies that evolved into Megger. Interestingly, Evershed & Vignoles also developed the World’s first high resistance ohmmeter in 1889.

A new addition to an impressive line-up of low resistance ohmmeters, the Megger DLRO100 series is comprised of three instruments; each model available as a mains powered unit or as a battery/mains powered unit.

The most advanced model is capable of remote operation, asset tagging, communicating wirelessly using Bluetooth and is also DualGround compatible for additional safety. These features coupled with a CAT IV 600VAC/500VDC safety rating and IP54 protection against dust and water ingress position the DLRO100 as a stalwart benchmark for any opposition in the market.

Regular inspection and testing of a Solar PV installation not only qualifies that the system remains electrically safe for continued use, but that it operates as efficiently as originally intended.

The IET guidance note (Code of Practice for Grid Connected Solar Photovoltaic Systems) provides engineers with a more user-friendly approach to installing and maintaining a PV system than that of BS EN 62446; the international standard upon which the guidance note is based.

April 2016 saw the arrival of a new batch of Megger multifunction testers. The untrained eye won’t spot any aesthetical or ergonomic differences between the existing MFT1700 series and the 2016 units, however the newer models offer additional, valuable testing features at very competitive prices.

The common misconception of a lack of electric vehicle charging points in the UK is the prime argument for reasons against investing in an electric vehicle.

If truth be told, there are currently 1,500 public EV charging points across the UK. And with the government investing £30m into eight pilot regions, this number is expected to increase to 8,500 over the coming years.

Infrared thermography has been used for decades by skilled, trained users in a huge range of applications, from structural surveying of buildings through to electromechanical fault diagnosis, from tracking wild animals to clandestine military activities.

Ask any seasoned thermographer and they’ll regale you with tales of expensive, finicky equipment that had to be treated with kid gloves, was bulky and chomped through batteries. It wasn’t long ago that thermographic cameras had their own specialised on-board cooling systems.

Wireless Technology

Wireless communication is an integral part of today’s society with nearly 800 million households worldwide using a WiFi network. In fact, at the end of 2013 there were more wireless mobile devices on Earth than people.

As any electrician knows, it’s very straightforward to trace cables… providing you can see them. As soon as they’re buried in walls or under floor spaces, finding cables becomes a laborious combination of educated guesswork, luck and dogged persistence, aided by an insight into whatever was going on in the crazed mind of the person who installed them in such a bizarre topology.

Cable finders such as the Martindale CD1000 and CEM CLS20 claim to put an end to all your cable-finding problems. But do they deliver all they promise? And which should you spend your money on: the CLS20 (currently £119 + VAT), or the CD1000 (£259 + VAT)?

The Megger MFT1720 is one of the most popular testers within the Megger MFT17XX range. Domestic installers who might undertake future three-phase installation work will consider the MFT1720, as will any engineer conducting EICR’s or undertaking volumes of domestic and commercial installation work. In short, The Megger MFT1720 is a great all round multifunction tester suitable for domestic, commercial and some industrial electrical installations.
