Power systems theory - generation, transmissions and distribution
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...
Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading...
This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
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...
Over recent years the Lithium Ion battery has become popular in applications requiring high power densities with small weight and footprint. Today Lithium...
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...
How often installations are inspected is up to the owner of the installation, provided such durations do not exceed any regulatory maximums in force. ...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
