Electrical Substation Wikipedia

Electrical substation - Wikipedia.

A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels..


Power station - Wikipedia.

History. In early 1871 Belgian inventor Zenobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry.. In 1878, a hydroelectric power station was designed and built by William, Lord Armstrong at Cragside, England.It used water from lakes on his estate to power Siemens dynamos.The electricity supplied power to lights, heating, ....


Three-phase electric power - Wikipedia.

Three-phase electric power (abbreviated 3?) is a common type of alternating current used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power.. Three-phase electrical power was ....


New York City blackout of 1977 - Wikipedia.

The New York City blackout of 1977 was an electricity blackout that affected most of New York City on July 13-14, 1977. The only unaffected neighborhoods in the city were in southern Queens (including neighborhoods of the Rockaways), which were part of the Long Island Lighting Company system, as well as the Pratt Institute campus in Brooklyn, and a few other large ....


Electrical grid - Wikipedia.

An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of: power stations: often located near energy and away from heavily populated areas; electrical substations to step voltage up or down; electric power transmission to carry power long ....


Metcalf sniper attack - Wikipedia.

On April 16, 2013, an attack was carried out on Pacific Gas and Electric Company's Metcalf transmission substation in Coyote, California, near the border of San Jose.The attack, in which gunmen fired on 17 electrical transformers, resulted in more than $15 million worth of equipment damage, but it had little impact on the station's electrical power supply..


Generic Substation Events - Wikipedia.

Generic Substation Events (GSE) is a control model defined as per IEC 61850 which provides a fast and reliable mechanism of transferring event data over entire electrical substation networks. When implemented, this model ensures the same event message is received by multiple physical devices using multicast or broadcast services. The GSE control model is further subdivided ....


Kingsnorth power station - Wikipedia.

Kingsnorth Power Station was a dual-fired coal and oil power station on the Hoo Peninsula at Medway in Kent, South East England.The four-unit station was operated by energy firm E.ON UK, and had a generating capacity of 2000 megawatts. It was capable of operating on either coal or oil though in practice oil was used only as a secondary fuel or for startup..


Electrical resistance and conductance - Wikipedia.

The electrical resistance of an object is a measure of its opposition to the flow of electric current.Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes.Electrical resistance shares some conceptual parallels with mechanical friction.The SI unit of electrical resistance is the ohm (), while electrical conductance is ....


Cogeneration - Wikipedia.

Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time.. Cogeneration is a more efficient use of fuel or heat, because otherwise-wasted heat from electricity generation is put to some productive usebined heat and power (CHP) plants recover otherwise wasted thermal energy for ....


List of International Electrotechnical Commission standards - Wikipedia.

IEC 61557 Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c. - Equipment for testing, measuring or monitoring of protective measures; ... (HVDC) substation audible noise; IEC 61975 High-voltage direct current (HVDC) installations - System tests;.


Electrical substation - Energy Education.

Electrical substations are the interface between parts of the distribution grid and transmission systems.These fenced off areas (see Figures 1 and 2) step down the voltage in the transmission lines to one that is suitable for the distribution grid. They are also equipped with circuit breakers to protect the distribution system, and can be used to control the flow of current in various ....


Electricity - Wikipedia.

Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.Various common phenomena are related to electricity, including lightning, static electricity, electric heating, ....


Pumped-storage hydroelectricity - Wikipedia.

Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing.The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically ....


Transformer - Wikipedia.

A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple 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 across any other coils wound around the same core. Electrical energy can be transferred ....


Magnetic field - Wikipedia.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents,: ch1 and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.: ch13 : 278 A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts ....


Stella power stations - Wikipedia.

History Development. The British demand for electricity increased after the Second World War. In the North East of England this led to the expansion of existing power stations at Dunston and Billingham in the late 1940s, the two new Stella power stations, and the construction of two more large stations built at Blyth later in the 1960s. This new generating capacity quickly met the ....


Micro combined heat and power - Wikipedia.

Micro combined heat and power, micro-CHP, uCHP or mCHP is an extension of the idea of cogeneration to the single/multi family home or small office building in the range of up to 50 kW. Usual technologies for the production of heat and power in one common process are e.g. internal combustion engines, micro gas turbines, stirling engines or fuel cells. ....
