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.
When looking at the design of a lighting scheme it is useful to have an understanding on the nature of light itself and some of the basic theory associated...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
There are a lot of interesting two page type notes on various medium voltage topics – switchgear, circuit breakers, bus systems etc. It is on the Siemens...
IEC 60947 is the circuit breaker standard and covers the marking of breakers in detail. Any manufacturer following this standard should comply with the...
