Fundamental electrical engineering concepts and theory
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...
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...
It wasn't so long ago I was telling someone that I don't use rules of thumb as most things are easily calculated anyhow. As it turns out I last week...
Circuit breakers are switching devices whose primary function is to isolate parts of an electrical distribution system in the even of abnormal conditions...
Insulation on a motor prevents interconnection of windings and the winding to earth. When looking at motors, it is important to understand how the insulation...
This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...
Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
Electromechanical relays have been the traditional backbone of electrical protection systems. While over recent years these have been replaced by microprocessor...
