Electric Power System
An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the Electric generator, generators that supply the power, the electric power transmission, transmission system that carries the power from the generating centers to the Distribution board, load centers, and the electric power distribution, distribution system that feeds the power to nearby homes and industries. Smaller power systems are also found in industry, hospitals, commercial buildings, and homes. A single line diagram helps to represent this whole system. The majority of these systems rely upon three-phase electric power, three-phase AC power—the standard for large-scale power transmission and distribution across the modern world. Specialized power systems that do not always rely upon thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Induction Motor
An induction motor or asynchronous motor is an AC motor, AC electric motor in which the electric current in the rotor (electric), rotor that produces torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor therefore needs no electrical connections to the rotor. An induction motor's rotor can be either wound rotor motor, wound type or squirrel-cage rotor, squirrel-cage type. Three-phase Squirrel-cage rotor, squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable, and economical. Single-phase electric power, Single-phase induction motors are used extensively for smaller loads, such as garbage disposals and stationary power tools. Although traditionally used for constant-speed service, single- and three-phase induction motors are increasingly being installed in variable-speed applications using variable-frequency drives (VFD). VFD offers energy savings opportunities for i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Voltage Regulation
In electrical engineering, particularly power engineering, voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component, such as a transmission line, transmission or distribution line. Voltage regulation describes the ability of a system to provide near constant voltage over a wide range of Electrical load, load conditions. The term may refer to a passive property that results in more or less voltage drop under various load conditions, or to the active intervention with devices for the specific purpose of adjusting voltage. Electrical power systems In electrical power systems, voltage regulation is a dimensionless quantity defined at the receiving end of a transmission line as: :\text VR = \frac \times 100 where ''Vnl'' is voltage at no load and ''Vfl'' is voltage at full load. The percent voltage regulation of an ideal transmission line, as defined by a transmission line with zero Electrical resistance and conductance, res ...

Transformer
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple Electrical network, circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force, electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change Alternating current, AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signa ...

Miksa Déri
Miksa Déri (27 October 1854 in Bács, Austrian Empire – 3 March 1938) was a Hungarian electrical engineer, inventor, power plant builder. He contributed with his partners Károly Zipernowsky and Ottó Bláthy, in the development of the closed iron core transformer and the ZBD model. His other important invention was the constant voltage AC electrical generator in the Ganz Works in 1883. The missing link of a full Voltage sensitive - voltage intensive (VSVI) system was the reliable AC Constant Voltage generator. Therefore, the invention of the constant voltage generator at the Ganz Works had crucial role in the beginnings of the industrial scale AC power generating, because only these types of generators can produce a stated output voltage, regardless of the value of the actual load. ZBD was an abbreviation of the three men's names: Zipernowsky, Bláthy and Déri. Déri is also noted for inventing the single phase type of repulsion motor Education * There is secon ...

Károly Zipernowsky
Károly Zipernowsky (born as Carl Zipernowsky, 4 April 1853 in Vienna – 29 November 1942 in Budapest) was an Austrian-born Hungarian electrical engineer. He invented the transformer with his colleagues ( Miksa Déri and Ottó Bláthy) at the famous Hungarian manufacturing company Ganz Works and he contributed significantly with his works also to other AC technologies. Biography Zipernowsky, with Ottó Bláthy and Miksa Déri, all of Ganz and Company, were researching ways of increasing efficiency of electrical power transmission. They experimented with power supplies and current transformation, which led to the invention of the ZBD alternating current transformer in 1885. The ZBD system is based on a closed-iron ring core with an arbitrary diameter and a coil around the core, which conducts AC current. Their system converted higher voltage suitable for energy transmission to lower "''service''"-level voltage (step-down transformer). Nikola Tesla Nikola Tesla ...
