Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing the impact of varying voltages, the... read more..
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical components, the unbalance system is broken dow... read more..
We have a sister note to this (Robots - Interesting Video), in which I have posted some videos of interesting robots developed by commercial corporations and institutions. While these are great... read more..
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
A couple of months ago I came Microsoft's OneNote and downloaded the 60 day free trail. Since then I have been using it regularly and now have a full license...
Using software in our work is essential for most of us and we are becoming even more dependant on it's use. While software is a great asset, many times...
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...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
The robot folding towels post below was interesting enough at the time to post a link. Recently I’ve come across a couple of other interesting videos...

Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
Fire resistant and fire retardant cable sheaths are design to resist combustion and limit the propagation of flames. Low smokes cables have a sheath designed...
