Fundamental electrical engineering concepts and theory
Years ago I was told that you should always try to write the best report you can. Many years later I still think on this as one of the better pieces of...
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...
Estimating maximum demand is a topic frequently discussed. Working out how much power to allow for a building can be very subjective . Allowing too much...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy. Every year more and more PV systems are installed...
Circuit breakers are switching devices whose primary function is to isolate parts of an electrical distribution system in the even of abnormal conditions...
At the beginning of the year China put the world's first 1,000 kV UHV transmission system into operation. Transmitting power at over a million volts is...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
