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

A frequent problem in fault calculations is the obtaining of equipment parameters.  While it is always preferable to use the actual parameters of the equipment...

Coils of wire on the rotor carry a d.c. current which generates a magnetic field. A stator magnetic field is created using either permanent magnets or...

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...

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...

It's been a busy few months on different projects or busy couple of decades depending on how I look at it. I can say that on the odd (frequent) occasion...

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...

The robot folding towels post below was interesting enough at the time to post a link.  Recently I’ve come across a couple of other interesting videos...

The new standard IEC 61439 replaces the old 60439. Compared to the old standard, the new 61439 is a more clearly defined and takes into account the assembly...

Motor starting and its associated problems are well-known to many people who have worked on large industrial processes. However, these things are, of course...
