Just added a page to the tools, which will allow you to calculate the synchronous speed, slip and rated torque for an induction motor. Not a particularly...
Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy. Every year more and more PV systems are installed...
A fundamental concept behind the operation of alternating current systems is that voltage and current waveforms will be sinusoidal – a Sine Wave. This...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
Dielectrics (insulating materials for example) when subjected to a varying electric field, will have some energy loss. The varying electric field causes...
Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...
In electrical engineering, Network Theory is the study of how to solve circuit problems. By analyzing circuits, the engineer looks to determine the various...
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...
