A load flow study is the analysis of an electrical network carried out by an electrical engineer. The purpose is to understand how power flows around...

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...

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...

Traditionally substations have used circuit breakers, current transformers (CT), voltage transformers (VT) and protection relays all wired together using...

In 2011, with the introduction of it’s Panda search ranking algorithms, Google introduced tools for determining the original author of posts.  The intention...

Resistors are electronic components that oppose the flow of current.  Manufactured in various types and ranges they have a wide application to electronics...
