Fundamental electrical engineering concepts and theory
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
The (relatively new) switchgear and control gear standard, IEC 61439 'Low-voltage switchgear and controlgear assemblies' has three methods which can be...
Many medium voltage (MV) indoor switchgear rooms exist worldwide. The complexity of these rooms varies considerably depending on location, function and...
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.
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
A single phase system is perhaps the most common type of system most people are familiar with. This is what people have in their homes and what appliances...
One of the fundamental requirements of an alternating current distribution systems it to have the ability to change the magnitude of voltages. It is more...
Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...
Power factor is the ratio between the real power (P in kW) and apparent power (S in kVA) drawn by an electrical load. The reactive power (Q in kVAr)...
