Fundamental electrical engineering concepts and theory
A recurring theme on our forums is cable sizing. Now many installations are unique and require special consideration. However, a lot of the time things...
When thinking about watts (W) or kilowatt (kW = 1000 W) it can be useful too keep in mind the fundamental ideas behind the unit. Watt is not a pure electrical...
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
While there are a vast array of cable insulation materials, these are often divided into two general types; Thermoplastic or Thermosetting. For example...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
This is the first of two posts on the resistance of conductors. In the next post I will look at the ac resistance, including skin effect and we deal with...
