Fundamental electrical engineering concepts and theory
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
IEC 60287 "Calculation of the continuous current rating of cables (100% load factor)" is the International Standard which defines the procedures and equations...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
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...
A single phase system is perhaps the most common type of system most people are familiar with. This is what people have in their homes and what appliances...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
Laplace transforms and their inverse are a mathematical technique which allows us to solve differential equations, by primarily using algebraic methods...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
