Fundamental electrical engineering concepts and theory
This is the first of two posts on the resistance of conductors. In the next post I will look at the ac resistance, including skin effect and we deal with...
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
Our cable sizing tool is one of the more popular tools on the site. The tool enables cables to be sized in compliance with BS 7671 (the IEE Wiring Regulations...
Famed English chemist and physicist Michael Faraday was born on September 22, 1791, in Newington Butts, a suburb of Surrey just south of the London Bridge...
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...
Collection of links to various places with useful motor information. I’ll try and return to the page every now and again to update it with any motor notes...
Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
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...
Power factor is the ratio between the real power (P in kW) and apparent power (S in kVA) drawn by an electrical load. The reactive power (Q in kVAr)...
