Using software in our work is essential for most of us and we are becoming even more dependant on it's use. While software is a great asset, many times...
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...
Fire resistant and fire retardant cable sheaths are design to resist combustion and limit the propagation of flames. Low smokes cables have a sheath designed...
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...
The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.
The image (reproduced from IEC 60909) shows a typical fault in an ac system. From the illustration it can seen that there is an initial dc component ...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
Coils of wire on the rotor carry a d.c. current which generates a magnetic field. A stator magnetic field is created using either permanent magnets or...
In 2011, with the introduction of it’s Panda search ranking algorithms, Google introduced tools for determining the original author of posts. The intention...
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...
