Fundamental electrical engineering concepts and theory
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.
The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...
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)...
Motor starting and its associated problems are well-known to many people who have worked on large industrial processes. However, these things are, of course...
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...
