Electric motors are one of the most widely used items of electrical equipment. Improving motor efficiency benefits include, reduced power demand, lower...

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

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...

The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.

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...

Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy.  Every year more and more PV systems are installed...

Our question and answer system while letting you do exactly what it says, is much more.  It is a dynamic user driven system, where our users not only ask...

Recently I have seen a few interesting articles on viable cold fusion; the combining of atoms at room like temperatures to create boundless energy. Now...

Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...

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...
