Fundamental electrical engineering concepts and theory
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
If you have a great idea or invent something the last thing you want is someone to steal the idea. One of the things you can do is protect the intellectual...
Anyone specifying or using electric motors should have a basic understanding how the insulation is related to temperature. Three classes of insulation...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
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...
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...
The European Union is implementing a voluntary code of practice for participants with the aim of improving the overall efficiency of data centres. As part...
One of the requirements to ensuring that everything works is to have equipment selected, manufactured and verified [tested] to IEC standards. Not all equipment...
Various arguments exist around SF6 Gas Insulated (GIS) and Air Insulated (AIS) medium voltage switchgear. Recently we had to change a GIS design to AI...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
