Fundamental electrical engineering concepts and theory
GE have put together a time-lapse video shown flight take-off and landings at some airports. An interesting view:
ABB has produced a range of technical guides that offer concise explanations of the major technologies and technical issues in low voltage AC drives. ...
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...
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...
Anyone specifying or using electric motors should have a basic understanding how the insulation is related to temperature. Three classes of insulation...
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...
When selecting a generator, there are inherent limits on the active and reactive power which can be delivered. Generators are normally sized for a certain...
In a previous article I looked at the dc resistance of conductors and in this article we turn our attention to ac resistance. If you have not read the...
Current transformers (CTs) are used to convert high level currents to a smaller more reasonable level for use as inputs to protection relays and metering...
