Fundamental electrical engineering concepts and theory
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
One of the requirements to ensuring that everything works is to have equipment selected, manufactured and verified [tested] to IEC standards. Not all equipment...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
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...

We have had the Wiki with us for a long time now, but at last I have decided to say bye bye – more details on why below.
I received this question by email a few weeks. First thoughts was that it is a product of the mathematics of rotating a straight conductor in a magnetic...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
Request to look at induction motor starting time have come up a few times on the site. Hopefully in this post, I give you guys some idea on how to calculate...
