Fundamental electrical engineering concepts and theory
Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...
In the previous note we looked at the approach taken by the standard to the sizing of cables and illustrated this with an example. We then looked at one...
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...
A load flow study is the analysis of an electrical network carried out by an electrical engineer. The purpose is to understand how power flows around...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
The (relatively new) switchgear and control gear standard, IEC 61439 'Low-voltage switchgear and controlgear assemblies' has three methods which can be...
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...
I think this post is going to be helpful to several of our readers. While the IEC low voltage circuit breaker Standard [IEC 60947-2, Low voltage switchgear...
A frequent problem in fault calculations is the obtaining of equipment parameters. While it is always preferable to use the actual parameters of the equipment...
