Fundamental electrical engineering concepts and theory
If you have a great idea or invent something the last thing you want is someone to steal the idea. One of the things you can do is protect the intellectual...
Collection of links to various places with useful motor information. I’ll try and return to the page every now and again to update it with any motor notes...
This is the first of two posts on the resistance of conductors. In the next post I will look at the ac resistance, including skin effect and we deal with...
Photovoltaic (PV) systems are typically more efficient when connected in parallel with a main power gird. During periods when the PV system generates energy...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
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...
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...
Electrical engineering has a multitude of laws and theorems. It is fair to say the Ohm's Law is one of the more widely known; it not the most known. Developed...
HTML supports a variety of entity symbols which can be entered using either numbers or an entity name. The number or name is preceded by the ‘&’ sign...
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...
