Fundamental electrical engineering concepts and theory
IEC 61439 'Low-voltage switchgear and controlgear assemblies', specifies standard arrangements of switchboard (call forms of internal separation). The...
Lamps are the essential part of any luminaire. These are the light generating components. Since the advent of electrical lighting in the middle of the...
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...
Laplace transforms and their inverse are a mathematical technique which allows us to solve differential equations, by primarily using algebraic methods...
If you are working on a large plan, get the real coordinates [latitude, longitude] for two or more points and add them to the drawing. That way you can...
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...
Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...
When current flows within a wire, a magnetic field is created. The potion of this magnetic field perpendicular to the wire is called the magnetic flux...
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
