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, sometimes these are not available... read more..
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
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 and answer questions, but can manage the... read more..
When current flows within a wire, a magnetic field is created. The potion of this magnetic field perpendicular to the wire is called the magnetic flux (measured in weber, Wb). Inductance is the ratio... read more..
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
Installation of a UPS can help in reducing problems due to issues with the power supply. A lot of people relate this to nine key issues. Depending on...
It wasn't so long ago I was telling someone that I don't use rules of thumb as most things are easily calculated anyhow. As it turns out I last week...
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...
At the beginning of the year China put the world's first 1,000 kV UHV transmission system into operation. Transmitting power at over a million volts is...
When selecting a generator, there are inherent limits on the active and reactive power which can be delivered. Generators are normally sized for a certain...
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...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
In electrical engineering, Network Theory is the study of how to solve circuit problems. By analyzing circuits, the engineer looks to determine the various...
The robot folding towels post below was interesting enough at the time to post a link. Recently I’ve come across a couple of other interesting videos...
