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...

Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...

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...

I think this post is going to be helpful to several of our readers. While the IEC low voltage circuit breaker Standard [IEC 60947-2, Low voltage switchgear...

Sometimes it’s useful to be able to quickly lookup a piece of technical information.  This note is a collection of information related to motors, and in...

Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...

The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.

In three phase systems, the use of transformers with three windings (or legs) per side is common.  These three windings are often connected in delta or...

If your are ever called out to troubleshoot something on your electrical system, one of the first things consider is the supply voltage. You want to ensure...

If you are working on a large plan, get the real coordinates [latitude, longitude] for two or more points and add them to the drawing. That way you can...
