Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development of power electronics during the last ... read more..
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
Exposure to time varying magnetic fields, from power frequencies to the gigahertz range can have harmful consequences. A lot of research has been conducted...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
Reading is a bit of a hobby of mine and I"ve done a few off-topic posts in the past on this. Rather than continue doing the occasional post I thought ...

Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
The standard aims to consolidate AC and traction voltages within the industry and defines the following bands: band 1 - A.C. systems 100 V to 1...
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...
