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:
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...
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
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...
In electrical engineering, Network Theory is the study of how to solve circuit problems. By analyzing circuits, the engineer looks to determine the various...
The correct sizing of current transformers is required to ensure satisfactory operation of measuring instruments and protection relays. Several methods...
In an earlier note on the site [Photovoltaic (PV) - Electrical Calculations], the theory of solar (PV) cell calculations was introduced. In particular...
How often installations are inspected is up to the owner of the installation, provided such durations do not exceed any regulatory maximums in force. ...
Control theory looks at how systems work and are controlled from a mathematical view. This note gives a brief introduction to some of the concepts – more...
I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...
