A NAPIT expert answers your technical question

As part of our ongoing support for apprentices across the UK, we’ve teamed up with the technical experts from NAPIT to help answer your questions. his question recently came on from an apprentice named Josh. Question: I am stuck on this equation. Please can you help? Determine the power factor for a 2kw load that draws 15A from a 230 V supply. Answer: then W divided by VA 2000…

SELECT and SJIB launch engaging new apprentice animation explaining the steps to a successful FICA

SELECT and the Scottish Joint Industry Board (SJIB) have once again teamed up to develop another eye-catching animation – this time shining the spotlight on the Final Integrated Competence Assessment (FICA). As testing centres prepare to reopen next week, and apprentices across Scotland pick up their tools and books again, the two-minute film gives an overview of exactly what the important assessment entails. From preparing a pre-FICA checklist to what to expect…

How smart circuit protection can help provide additional protection for properties

You could be forgiven for thinking that circuit protection devices are not “smart”. It’s an easy mistake to make when your go-to’s are comparatively simple devices like MCBs and RCDs, which have been around for a long time and which are decidedly not smart. Even though these familiar technologies are appropriately used to help to provide particular levels of safety in electrical installations and to provide protection, for people and…

Safety video promotes positive change

The preventable death of Louise Taggart’s brother, Michael, when he was aged just 26 is the personal tragedy which now sees her as a workplace health and safety guest speaker (she was formerly an employment lawyer) travelling the country presenting to employers and conferences. It’s been levelled at Louise that she is on a mission to which she says quite firmly: “Absolutely. I’m on a mission to ensure that lessons…

Harmonics Standards: What are they and how can you use them?

The purpose of power quality measurements is to classify basic measurements of voltage and current in such a way that the state of health of the electrical system can be quantified. One of the key measurement quantities is harmonics. Harmonics are voltages or currents with frequency components that are integer multiples of the frequency of the applied AC voltage, or fundamental power frequency. When AC voltage is applied to resistive…

Solving electrical problems with thermal imaging

Basic how-tos: Electrical load, safety, and emissivity Today’s thermal imagers are rugged, easy to use, and much more affordable than even just a few years ago. They have become a realistic solution for everyday electrical maintenance. To use, a qualified technician or electrician points the thermal imager at the equipment in question and scans the immediate area, looking for unexpected hot spots. The imager produces a live image of the heat emitted from the equipment and with the quick squeeze of the trigger, a…
