Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...

Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...

This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.

Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...

While there are a vast array of cable insulation materials, these are often divided into two general types; Thermoplastic or Thermosetting. For example...

I've recently come across this question a couple times browsing the internet. Decided to give a quick answer here. A rectifier transformer is a transformer...

Dielectrics (insulating materials for example) when subjected to a varying electric field, will have some energy loss.   The varying electric field causes...

I think this post is going to be helpful to several of our readers. While the IEC low voltage circuit breaker Standard [IEC 60947-2, Low voltage switchgear...
