Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...

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...

If you have no idea how electrical circuits work, or what people mean then they talk about volts and amps, hopefully I can shed a bit light.  I’m intending...

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...

In electrical engineering, Network Theory is the study of how to solve circuit problems. By analyzing circuits, the engineer looks to determine the various...

Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...

Low voltage (LV) switchrooms are common across all industries and one of the more common spatial requirements which need to be designed into a project...

This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
