Fundamental electrical engineering concepts and theory
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
Our IEE cable sizing was wrote a few years ago and had become rough around the edges. I thought it was time to give the tool a service. Unfortunately when...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
We have a sister note to this (Robots - Interesting Video), in which I have posted some videos of interesting robots developed by commercial corporations...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
I received this question by email a few weeks. First thoughts was that it is a product of the mathematics of rotating a straight conductor in a magnetic...
The (relatively new) switchgear and control gear standard, IEC 61439 'Low-voltage switchgear and controlgear assemblies' has three methods which can be...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...
