Fundamental electrical engineering concepts and theory
In a previous article I looked at the dc resistance of conductors and in this article we turn our attention to ac resistance. If you have not read the...
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
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...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
IEC 60287 "Calculation of the continuous current rating of cables (100% load factor)" is the International Standard which defines the procedures and equations...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
Capacitors have numerous applications in electrical and electronic applications. This note examines the use of capacitors to store electrical energy....
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...
