Fundamental electrical engineering concepts and theory
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
The windings of many medium and small sized transformers are protected by restricted earth fault (REF) systems. The illustration shows the principal of...
If you have a great idea or invent something the last thing you want is someone to steal the idea. One of the things you can do is protect the intellectual...

I was reminded of Occam's Razor while reading a book. It's quite a simple principal of logic which has stood the test of time and is accepted as central...
Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...
Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...
Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
