Fundamental electrical engineering concepts and theory
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
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...
When thinking about watts (W) or kilowatt (kW = 1000 W) it can be useful too keep in mind the fundamental ideas behind the unit. Watt is not a pure electrical...
Earthing of electrical systems is essential for the correct functioning and the protecting of life and equipment in the event of faults. The earth electrode...
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...
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
Often us engineers get so bogged down in equations, using software, producing drawings and writing specifications that this becomes the sole focus. ...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
IEC 60228 is the International Electrotechnical Commission's international standard on conductors of insulated cables. Among other things, it defines a...
Steel ladders, trays and baskets form the backbone of cable containment systems. Often these items need some form of surface treatment to prevent corrosion...
