When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
The IET site has a video of a visit showing of a high tech meeting room developed at Napier University in Edinburgh. It a good demonstration of innovative...
In the previous note we looked at the approach taken by the standard to the sizing of cables and illustrated this with an example. We then looked at one...
We have had the Wiki with us for a long time now, but at last I have decided to say bye bye – more details on why below.
