Fundamental electrical engineering concepts and theory
If you are wondering what happened to our cable notes, the short answer is that we have moved them to myCableEngineering.com. The "Knowledge Base" at...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
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...
I was having a conversation the other day about voltage levels. While everyone was in agreement that low voltage was 1000 V and less, there was more confusion...
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...
