Sparks Electrical News September 2020 coverFrom 7-11 September, industry players will unite in celebration of Electra Mining Africa through participation in Electra Mining Africa 2020 Connect, its live industry webinar series and product showcases.

Electrical Compliance – who is to blame when things go wrong?

It is a warm summer afternoon and you have just shown your son how the electric lawnmower works. He is demonstrating his newly acquired skill when the unthinkable happens: he accidentally cuts through the electrical cord and falls to the ground.

The ultraviolet calibration and measurement capabilities at NMISA

Ultraviolet radiation (UV or UVR) is electromagnetic radiation with a wavelength shorter than visible light, but longer than x-rays, with focus on the non-ionising part of the UV spectrum (Figure 1). The International Commission on Illumination (CIE) subdivides UV radiation into three bands: UV-A from 315 nm to 400 nm, UV-B from 280 nm to 315 nm and UV-C from 100 nm to 280 nm.
