Fundamental electrical engineering concepts and theory
The term 'N+1' relates to redundancy and simply means that if you required 'N' items of equipment for something to work, you would have one additional...
If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
In an earlier note on the site [Photovoltaic (PV) - Electrical Calculations], the theory of solar (PV) cell calculations was introduced. In particular...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
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.
Recently I have seen a few interesting articles on viable cold fusion; the combining of atoms at room like temperatures to create boundless energy. Now...
Coils of wire on the rotor carry a d.c. current which generates a magnetic field. A stator magnetic field is created using either permanent magnets or...
Some colleagues had an issue earlier in the week on sizing conduits to be cast in concrete for some power cables . It became clear that none of us had...
