Fundamental electrical engineering concepts and theory
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
In an earlier note on the site [Photovoltaic (PV) - Electrical Calculations], the theory of solar (PV) cell calculations was introduced. In particular...
While there are a vast array of cable insulation materials, these are often divided into two general types; Thermoplastic or Thermosetting. For example...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
I've recently come across this question a couple times browsing the internet. Decided to give a quick answer here. A rectifier transformer is a transformer...
Our cable sizing tool is one of the more popular tools on the site. The tool enables cables to be sized in compliance with BS 7671 (the IEE Wiring Regulations...
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.
