Power systems theory - generation, transmissions and distribution
Capacitors have numerous applications in electrical and electronic applications. This note examines the use of capacitors to store electrical energy....
The (relatively new) switchgear and control gear standard, IEC 61439 'Low-voltage switchgear and controlgear assemblies' has three methods which can be...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
IEC 61439 'Low-voltage switchgear and controlgear assemblies', specifies standard arrangements of switchboard (call forms of internal separation). The...
Dielectrics (insulating materials for example) when subjected to a varying electric field, will have some energy loss. The varying electric field causes...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
IEEE TV has a part series of videos on wind power and it's implication. For a really good overview to the technologies and issues around wind power, these...
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...
When current flows within a wire, a magnetic field is created. The potion of this magnetic field perpendicular to the wire is called the magnetic flux...
Years ago I was told that you should always try to write the best report you can. Many years later I still think on this as one of the better pieces of...
