This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
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.
The other day I came across an article in Technology Review on the development of a smart transformer. A professor at North Carolina State University is...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
It's been a busy few months on different projects or busy couple of decades depending on how I look at it. I can say that on the odd (frequent) occasion...
Bored at work and would rather be playing trump card game with you son. The next best thing (or not) maybe the online cable trump card game from AEI Cables...

"I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong...
Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...
In a previous article I looked at the dc resistance of conductors and in this article we turn our attention to ac resistance. If you have not read the...
