Fundamental electrical engineering concepts and theory
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...
Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...
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...
A single phase system is perhaps the most common type of system most people are familiar with. This is what people have in their homes and what appliances...
I was digging in my bookshelf and came across the 80th Anniversary Association of Mine Resident Engineers, Papers and Discussions Commemorative Edition...
Power cables can basically be classified into earthed and unearthed cables, where earthed and unearthed refer to the application for which the cable is...
Electromechanical relays have been the traditional backbone of electrical protection systems. While over recent years these have been replaced by microprocessor...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
Over recent years the Lithium Ion battery has become popular in applications requiring high power densities with small weight and footprint. Today Lithium...
I was having a conversation the other day about voltage levels. While everyone was in agreement that low voltage was 1000 V and less, there was more confusion...
