Fundamental electrical engineering concepts and theory
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...
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
Everything physical in electrical engineering from insulations to conductors revolves around materials. Here we are listing common materials along with...
Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy. Every year more and more PV systems are installed...
Many medium voltage (MV) indoor switchgear rooms exist worldwide. The complexity of these rooms varies considerably depending on location, function and...
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...
IEC 60228 is the International Electrotechnical Commission's international standard on conductors of insulated cables. Among other things, it defines a...
One of the comments on my Motor Starting Series was asking for something on duty cycles. Here it is. As a purchaser of a motor, you have responsibility...
Request to look at induction motor starting time have come up a few times on the site. Hopefully in this post, I give you guys some idea on how to calculate...
It wasn't so long ago I was telling someone that I don't use rules of thumb as most things are easily calculated anyhow. As it turns out I last week...
