Power systems theory - generation, transmissions and distribution
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...

When sizing cables, the heat generated by losses within any sheath or armour need to be evaluated. When significant, it becomes a factor to be considered...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
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...
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 following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
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...
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...
