Fundamental electrical engineering concepts and theory
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
Carrying out a protection system discrimination study is critical to ensure the correct functioning of the electrical system in the event of faults. ...
In an earlier note on the site [Photovoltaic (PV) - Electrical Calculations], the theory of solar (PV) cell calculations was introduced. In particular...
There are a lot of interesting two page type notes on various medium voltage topics – switchgear, circuit breakers, bus systems etc. It is on the Siemens...
Our IEE cable sizing was wrote a few years ago and had become rough around the edges. I thought it was time to give the tool a service. Unfortunately when...
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...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
