For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...

Gauss's Electrical law defines the relation between charge ("Positive" & "Negative") and electric field.  The law was initially formulated by Carl Friedrich...

GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:

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

Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission (IEC) National...

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...

American inventor Thomas Alva Edison was born in Milan, Ohio on February 11, 1847. He was the youngest of seven children and received little formal schooling...

The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...

If you have a great idea or invent something the last thing you want is someone to steal the idea. One of the things you can do is protect the intellectual...

Circuit breakers are switching devices whose primary function is to isolate parts of an electrical distribution system in the even of abnormal conditions...
