In three phase systems, the use of transformers with three windings (or legs) per side is common. These three windings are often connected in delta or star, resulting in common transformer conf... read more..
If you are working on a large plan, get the real coordinates [latitude, longitude] for two or more points and add them to the drawing. That way you can...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
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...
How often installations are inspected is up to the owner of the installation, provided such durations do not exceed any regulatory maximums in force. ...

While there are a vast array of cable insulation materials, these are often divided into two general types; Thermoplastic or Thermosetting. For example...
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...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
