Fundamental electrical engineering concepts and theory
Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...
Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...
The IEC publishes a series of documents and rules governing the preparation of documents, drawings and the referencing of equipment. Depending on country...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
Alternating current (a.c.) is the backbone of modern electrical power distribution. In this article I’ll be pulling some of the more important concepts...
Coils of wire on the rotor carry a d.c. current which generates a magnetic field. A stator magnetic field is created using either permanent magnets or...
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...
The fundamental component of any analogue computer is the operational amplifier, or op amp. An operational amplifier (often called an op-amp,) is a high...
Years ago I was told that you should always try to write the best report you can. Many years later I still think on this as one of the better pieces of...
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
