Fundamental electrical engineering concepts and theory
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...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
Low voltage (LV) switchrooms are common across all industries and one of the more common spatial requirements which need to be designed into a project...
If two dissimilar metals are touching and an external conducting path exists, corrosion of one the metals can take place. Moisture or other materials...
The image (reproduced from IEC 60909) shows a typical fault in an ac system. From the illustration it can seen that there is an initial dc component ...
If you are working on a large plan, get the real coordinates [latitude, longitude] for two or more points and add them to the drawing. That way you can...
Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
In a previous article I looked at the dc resistance of conductors and in this article we turn our attention to ac resistance. If you have not read the...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
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...
