Fundamental electrical engineering concepts and theory
Photovoltaic (PV) systems are typically more efficient when connected in parallel with a main power gird. During periods when the PV system generates energy...
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...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
Using software in our work is essential for most of us and we are becoming even more dependant on it's use. While software is a great asset, many times...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
In an earlier note on the site [Photovoltaic (PV) - Electrical Calculations], the theory of solar (PV) cell calculations was introduced. In particular...
Just added a page to the tools, which will allow you to calculate the synchronous speed, slip and rated torque for an induction motor. Not a particularly...
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...
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
Reading is a bit of a hobby of mine and I"ve done a few off-topic posts in the past on this. Rather than continue doing the occasional post I thought ...
