Fundamental electrical engineering concepts and theory
It's been a busy few months on different projects or busy couple of decades depending on how I look at it. I can say that on the odd (frequent) occasion...
Various arguments exist around SF6 Gas Insulated (GIS) and Air Insulated (AIS) medium voltage switchgear. Recently we had to change a GIS design to AI...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
Lamps are the essential part of any luminaire. These are the light generating components. Since the advent of electrical lighting in the middle of the...
Current transformers (CTs) are used to convert high level currents to a smaller more reasonable level for use as inputs to protection relays and metering...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
Carrying out a protection system discrimination study is critical to ensure the correct functioning of the electrical system in the event of faults. ...
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...
Bored at work and would rather be playing trump card game with you son. The next best thing (or not) maybe the online cable trump card game from AEI Cables...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
