Electric Generators
Posted under Industry, Power Source
Electric generators are all based on the fundamental concepts of electromagnetic induction developed by Michael Faraday in 1831. Faraday discovered that moving a conductor through a magnetic field induces an electromagnetic force (emf), or voltage, across the wire. A generator, very simply, is an arrangement of components designed to cause relative motion between a magnetic [...]
Electric Industry Utility
Posted under Industry, Power Source
Electric utilities, monopoly franchises, large central power stations, and long transmission lines have been the principal components of the prevailing electric power paradigm since the days of Insull. Electricity generated at central power stations is almost always three-phase, ac power at voltages that typically range from about 14 kV to 24 kV. At the site [...]
Electric Industy Pioneers
Posted under Industry, Power Source
The path that leads to today’s enormous electric utility industry began in earnest in the nineteenth century with the scientific descriptions of electricity and magnetism by giants such as Hans Christian Oersted, Andr´e Marie Amp`ere, and James Clerk Maxwell. The development of electromechanical conversion technologies such as the direct-current dynamos developed in 1831 separately by [...]
Three Phase Systems
Posted under Energy, Power Source
We often heard the word three phase systems, some of us might know that it related to power / electrical switching systems, but what really are three phase systems? Lets discussed it more further. Firstly commercial electricity are tends to use and produce three phase synchronous generators, and it is also almost always sent on [...]
Power Supplies
Posted under Energy, Power Source
These days, almost every home have electronic devices, and within those devices lays down power supplies as the main converter from power lines into low voltage power that will be use as energy or fuel. Everything from televisions to computers, copy machines, portable phones, electric-motor speed controls, and so forth virtually anything that has an [...]
