Fundamental electrical engineering concepts and theory
Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...
Multimeters are undoubtedly the most common item of electrical test equipment in use. Often it is the first piece of equipment people will turn to when...
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
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...
Recently I have seen a few interesting articles on viable cold fusion; the combining of atoms at room like temperatures to create boundless energy. Now...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...
A battery consists of one or more cells, each of which use stored chemical energy to produce electrical energy, There are many types of cells and these...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
Here’s list of some famous scientists. Deliberately short, with the aim to provide a quick memory jog or overview. If your looking for more detailed information...
