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...
The fundamental component of any analogue computer is the operational amplifier, or op amp. An operational amplifier (often called an op-amp,) is a high...
Multimeters are undoubtedly the most common item of electrical test equipment in use. Often it is the first piece of equipment people will turn to when...
I've been considering a blog on the 110 or 230 Volt issue for a while. While browsing the Internet I came across a great summary by Borat over at engineering...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
Per unit fault calculations is a method whereby system impedances and quantities are normalised across different voltage levels to a common base. By removing...
A load flow study is the analysis of an electrical network carried out by an electrical engineer. The purpose is to understand how power flows around...
Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
