I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...

Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...

We have had the Wiki with us for a long time now, but at last I have decided to say bye bye – more details on why below.

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...

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...

If you are working on a large plan, get the real coordinates [latitude, longitude] for two or more points and add them to the drawing. That way you can...

Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...

Working in the vicinity of electrical equipment poses an hazard. In addition to electric shock hazard, fault currents passing through air causes Arc Flash...

When current flows within a wire, a magnetic field is created. The potion of this magnetic field perpendicular to the wire is called the magnetic flux...

Using laser optical pulses the random number generator utilizes the time between arrival of random photos to generate the numbers, ensuring true accuracy...
