Fundamental electrical engineering concepts and theory
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
The new standard IEC 61439 replaces the old 60439. Compared to the old standard, the new 61439 is a more clearly defined and takes into account the assembly...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
The windings of many medium and small sized transformers are protected by restricted earth fault (REF) systems. The illustration shows the principal of...
We have a sister note to this (Robots - Interesting Video), in which I have posted some videos of interesting robots developed by commercial corporations...
Our question and answer system while letting you do exactly what it says, is much more. It is a dynamic user driven system, where our users not only ask...
Here’s list of some famous scientists. Deliberately short, with the aim to provide a quick memory jog or overview. If your looking for more detailed information...
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...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
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...
