Fundamental electrical engineering concepts and theory
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.
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
Exposure to time varying magnetic fields, from power frequencies to the gigahertz range can have harmful consequences. A lot of research has been conducted...
Various techniques exist to enable the correct selection of batteries for UPS applications. The procedure described below is one of the more common. ...
