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

If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...

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

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...

Electric motors are one of the most widely used items of electrical equipment. Improving motor efficiency benefits include, reduced power demand, lower...

The other day I came across an article in Technology Review on the development of a smart transformer. A professor at North Carolina State University is...

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...

Electrical engineering has a multitude of laws and theorems. It is fair to say the Ohm's Law is one of the more widely known; it not the most known. Developed...

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...

A lot of our members work in countries where PPE (personal protective equipment) is regulated or they work for companies/organizations which take employee...
