Fundamental electrical engineering concepts and theory
A load flow study is the analysis of an electrical network carried out by an electrical engineer. The purpose is to understand how power flows around...
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...
In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or...
The windings of many medium and small sized transformers are protected by restricted earth fault (REF) systems. The illustration shows the principal of...
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...
ABB has produced a range of technical guides that offer concise explanations of the major technologies and technical issues in low voltage AC drives. ...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Nikola Tesla was born exactly at midnight on July 10, 1856 in the tiny village of Smiljan, Lika in Croatia. In his late teens, Tesla left the village to...
Motor starting and its associated problems are well-known to many people who have worked on large industrial processes. However, these things are, of course...
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...
