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...
Our IEE cable sizing was wrote a few years ago and had become rough around the edges. I thought it was time to give the tool a service. Unfortunately when...
A recurring theme on our forums is cable sizing. Now many installations are unique and require special consideration. However, a lot of the time things...
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...
Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...
Fire resistant and fire retardant cable sheaths are design to resist combustion and limit the propagation of flames. Low smokes cables have a sheath designed...
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
In a previous article I looked at the dc resistance of conductors and in this article we turn our attention to ac resistance. If you have not read the...
