Fundamental electrical engineering concepts and theory
Estimating maximum demand is a topic frequently discussed. Working out how much power to allow for a building can be very subjective . Allowing too much...
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...
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 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...
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...
The other day I was talking to a colleague who is a building services consultant. Despite regularly specifying dry-type/cast resin transformers he was...
When looking at the design of a lighting scheme it is useful to have an understanding on the nature of light itself and some of the basic theory associated...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Sometimes it’s useful to be able to quickly lookup a piece of technical information. This note is a collection of information related to motors, and in...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
