Fundamental electrical engineering concepts and theory
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...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Electromagnetic compatibility (EMC) is the study of coordinating electromagnetic fields give off equipment, with the withstand (compatibility) of other...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
When sizing cables, the heat generated by losses within any sheath or armour need to be evaluated. When significant, it becomes a factor to be considered...
