Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
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...
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
