Fundamental electrical engineering concepts and theory
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
When sizing cables, the heat generated by losses within any sheath or armour need to be evaluated. When significant, it becomes a factor to be considered...
When making adding a Note to our site we have a great online WYSIWYG editor and things are pretty simple. However, if you prefer you can write, manage...
I've recently come across this question a couple times browsing the internet. Decided to give a quick answer here. A rectifier transformer is a transformer...
While not as popular as it once was, frame leakage protection does still have some use in some circumstances. In essence frame leakage is an earth fault...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
Steel ladders, trays and baskets form the backbone of cable containment systems. Often these items need some form of surface treatment to prevent corrosion...
When current flows within a wire, a magnetic field is created. The potion of this magnetic field perpendicular to the wire is called the magnetic flux...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
