  • Fever Screening: Thermal Imaging and Non-Contact Instruments

    Fever Screening

    On the 11th March 2020, The World Health Organisation (WHO), responsible for assessing the global developments of COVID-19, characterised the outbreak as a pandemic¹. As of 31st March 2020, it is reported that the pandemic has affected more than 179 countries, with more than 823,000 cases confirmed worldwide².

    WHO confidently write that ‘all countries can still change the course of this pandemic’, and in order to supress and control the virus, it advises that countries should take measures to ‘detect, test, treat, isolate, trace and mobilise their people in the response’³ to the global emergency.

  • Is an Increase in Green Energy Usage Keeping Electricians Safer?

    18th Edition The Rise Of Green Energy

    The 1st of January 2019 was a significant date on the electrical calendar, it was the day we at last saw the implementation of the 18th Edition of the IET wiring regulations. First introduced in July 2018, changes were made across the board as chapters were redesigned, rewritten or indeed introduced for the very first time. Definitions were altered, the scope was extended, and a declaration was made concerning only using the approved parts. Beyond these amendments however, perhaps the most important difference was the emphasis placed both directly and indirectly on green energy. Continue reading

  • Is it the End of the Road for SF6?

    Is it the End of the Road for SF6?

    Sulphur hexafluoride – SF6 – is widely used in the electricity distribution industry in medium- and high-voltage installations such as substations, transformers and power stations. It is an odourless, colourless, non-flammable gas that acts as an insulator and prevents explosions and fires brought about by short circuits.

    These qualities have made it the most common gas insulator for HV switchgear and use is increasing as a greater number of smaller generators come onto the grid. However, concern has been raised about the global warming potential of SF6 as use increases, perversely driven by increased demand for renewable energy.

  • What did we Learn from the UK’s August Power Cut?

    What did we learn from the August blackout?

    On 9th August, Britain experienced one of the biggest power cuts in a decade as over 1,000,000 people were left without power across England and Wales. As well as thousands of homes going without power, the blackout also had a massive disruptive effect on transport with problems on the rail network and at Newcastle airport in addition to disruption for community facilities and businesses. But what lessons can be taken from the outage?

  • HFO-1234YF in Automotive Air Conditioning

    HFO-1234YF in Automotive Air Conditioning

    From 2017, a change in the law required the introduction of a new refrigerant – HFO-1234YF (also known as R-1234YF) – in air-conditioning systems of vehicles, replacing the widely used R134a. This has implications for automotive engineers and HVAC technicians, particularly when it comes to using appropriate gas leak detectors.

  • Smart Meters: What is the State of the UK Rollout?

    Smart Meters: UK Rollout

    Energy suppliers are obliged by Ofgem to take all reasonable steps possible to have a smart meter installed in the premises of all their domestic and small business customers by the end of 20201. The benefits of smart meters from both a consumer and environmental point of view have been loudly trumpeted in press releases and advertisements, but significant doubts remain and the 2020 deadline looks more and more optimistic when set against the facts. So where is the UK’s smart meter project?
