Power systems theory - generation, transmissions and distribution
Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy. Every year more and more PV systems are installed...
Electrical engineering is a field that covers a wide variety of sub-fields, including electricity and electronics. It is a field that goes back to the...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
Alternating current (a.c.) is the backbone of modern electrical power distribution. In this article I’ll be pulling some of the more important concepts...
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...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
