The other day I was reading 'Night of the New Magicians' by Mary Pope Osborn with my son. The story is about a young boy and girl who travel back in time...
Maxwell's Equations are a set of fundamental relationships, which govern how electric and magnetic fields interact. The equations explain how these fields...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
Many medium voltage (MV) indoor switchgear rooms exist worldwide. The complexity of these rooms varies considerably depending on location, function and...
Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...

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...
The term 'N+1' relates to redundancy and simply means that if you required 'N' items of equipment for something to work, you would have one additional...
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...
