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...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
The other day I was reading 'Night of the New Magicians' by Mary Pope Osborn with my son. The story is about a young boy and girl who travel back in time...
A frequent problem in fault calculations is the obtaining of equipment parameters. While it is always preferable to use the actual parameters of the equipment...
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
One of the comments on my Motor Starting Series was asking for something on duty cycles. Here it is. As a purchaser of a motor, you have responsibility...
From the earliest times, humans have found ways to create light. Pre-historic peoples used natural materials (moss, grass, etc.) soaked in animal fat and...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
How often installations are inspected is up to the owner of the installation, provided such durations do not exceed any regulatory maximums in force. ...
