The (relatively new) switchgear and control gear standard, IEC 61439 'Low-voltage switchgear and controlgear assemblies' has three methods which can be...
Installation of a UPS can help in reducing problems due to issues with the power supply. A lot of people relate this to nine key issues. Depending on...
In a previous article I looked at the dc resistance of conductors and in this article we turn our attention to ac resistance. If you have not read 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...
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
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...
If you at all familiar with programs like office and outlook, then adding and editing posts is pretty straightforward and intuitive. However, there are...
Ever wondered what kind of power an aircraft uses when parked at the airport stand. Normally the aircraft generates it own power, but when parked with...
