Fundamental electrical engineering concepts and theory
Reading is a bit of a hobby of mine and I"ve done a few off-topic posts in the past on this. Rather than continue doing the occasional post I thought ...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
MIT OpenCourseWare, makes the materials used in teaching all MIT subjects available on the Web, free of charge, to any user in the world.
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
