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…

10 dumb things smart people do when testing electricity
Anyone who makes their living by working with electricity quickly develops a healthy respect for anything with even a remote chance of being “live.” Yet the pressures of the getting a job done on time or getting a mission-critical piece of equipment back on line can result in carelessness and uncharacteristic mistakes by even the most seasoned electrician. The list below was developed as a quick reminder of what not to do when taking electrical measurements.   1. Replace the…
