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.

Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...

This is the first of two posts on the resistance of conductors. In the next post I will look at the ac resistance, including skin effect and we deal with...

Cable insulation is used to provide electrical separation between conductors of  a cable.  During the historical development of cables, numerous types...

I've been considering a blog on the 110 or 230 Volt issue for a while.  While browsing the Internet I came across a great summary by Borat over at  engineering...
