Fundamental electrical engineering concepts and theory
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...
Often us engineers get so bogged down in equations, using software, producing drawings and writing specifications that this becomes the sole focus. ...
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...
This morning I was explaining how differential protection works to a junior engineer. To give him something to read I opened up the NPAG (Network Protection...
The mobile phone was born in 1973. They were the size of a brick and weighed a couple of kg, making them difficult to fit into your pocket. At a few thousand...

This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
