Fundamental electrical engineering concepts and theory
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
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...
If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
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...
The IEC publishes a series of documents and rules governing the preparation of documents, drawings and the referencing of equipment. Depending on country...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
The other day I came across an article in Technology Review on the development of a smart transformer. A professor at North Carolina State University is...
Our cable sizing tool is one of the more popular tools on the site. The tool enables cables to be sized in compliance with BS 7671 (the IEE Wiring Regulations...
The 27 km, Euro 6 billion Collider lies on the border between France and Switzerland, took nearly 30 years to complete. Some of the lofty goals for the...
