Berlin 380-kV Electric Line
The Berlin 380 kV electric line is a 38.3-km double-circuit high-voltage electric three-phase power line in Berlin. An unusual system for a municipality, it was installed by the West Berlin Bewag utility company during the division of the city. Since 1951, West Berlin had been cut off from the East Berlin and East German power networks, and maintained an independent power generation capacity that was not connected to any other power grid. Berlin was connected to the western European power grid in 1994, following German reunification, by extending the 380 kV line. The first section of the line, which entered service in 1977, was an interconnector that consisted of a 2.6 km overhead transmission line and an 8.1 km underground cable, which ran from Reuter power station in Spandau to Mitte substation in Tiergarten ("Mitte" means "central"; the district of Berlin-Mitte was then in East Berlin). It was the first time plastic insulators had been used. The overhead segm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe 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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Europe
Western Europe is the western region of Europe. The region's countries and territories vary depending on context. The concept of "the West" appeared in Europe in juxtaposition to "the East" and originally applied to the ancient Mediterranean world, the Roman Empire (Western Roman Empire and Eastern Roman Empire), and medieval "Christendom" (Western Christianity and Eastern Christianity). Beginning with the Renaissance and the Age of Discovery, roughly from the 15th century, the concept of ''Europe'' as "the West" slowly became distinguished from and eventually replaced the dominant use of "Christendom" as the preferred endonym within the region. By the Age of Enlightenment and the Industrial Revolution, the concepts of "Eastern Europe" and "Western Europe" were more regularly used. Historical divisions Classical antiquity and medieval origins Prior to the Roman conquest, a large part of Western Europe had adopted the newly developed La Tène culture. As the Roman domain ...

Marzahn
Marzahn () is a locality within the borough of Marzahn-Hellersdorf in Berlin. Berlin's 2001 administrative reform led to the former boroughs of Marzahn and Hellersdorf fusing into a single new borough. In the north the Marzahn locality includes the neighbourhoods of ''Bürknersfelde'' and ''Ahrensfelde'', an overbuilt strip of land which once had belonged to the Brandenburg municipality of Ahrensfelde and was incorporated into Berlin in 1990. Geography Subdivision Marzahn is divided into three zones (''Ortslagen''): *Marzahn-Nord (''Berlin-Ahrensfelde'') *Marzahn-Mitte *Marzahn-Süd History The historic village of Marzahn was first mentioned as ''Morczane'' in a 1300 deed by Margrave Albert III of Brandenburg-Salzwedel, when he granted the estates to the Friedland Cistercian abbey (in today's Neuhardenberg). After the Thirty Years' War it fell to Elector Frederick William of Brandenburg. The new village church was finished in 1871 according to plans by Friedrich August Stà ...

Friedrichshain
Friedrichshain () is a quarter (''Ortsteil'') of the borough of Friedrichshain-Kreuzberg in Berlin, Germany. From its creation in 1920 until 2001, it was a freestanding city borough. Formerly part of East Berlin, it is adjacent to Mitte, Prenzlauer Berg, Kreuzberg and Lichtenberg. Friedrichshain is named after the ''Volkspark Friedrichshain'', a vast green park at the northern border with Prenzlauer Berg. In the Nazi era, the borough was called '' Horst-Wessel-Stadt''. Friedrichshain is one of the trendy districts of Berlin and has experienced gentrification. Geography Friedrichshain is defined by the following roads and places, starting clock-wise in the west: Lichtenberger Straße, Mollstraße, Otto-Braun-Straße, Am Friedrichshain, Virchowstraße, Margarete-Sommer-Straße, Danziger Straße, Landsberger Allee, Hausburgstraße, Thaerstraße, Eldenaer Straße, S-Bahn-Trasse, Kynaststraße, Stralauer Halbinsel, Spree.

Electricity Pylon
A transmission tower, also known as an electricity pylon or simply a pylon in British English and as a hydro tower in Canadian English, is a tall structure, usually a steel lattice tower, used to support an overhead power line. In electrical grids, they are generally used to carry high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations; utility poles are used to support lower-voltage subtransmission and distribution lines that transport power from substations to electric customers. They come in a wide variety of shapes and sizes. Typical height ranges from , though the tallest are the towers of a span between the islands Jintang and Cezi in China's Zhejiang province. The longest span of any hydroelectric crossing ever built belongs to the powerline crossing of Ameralik fjord with a length of . In addition to steel, other materials may be used, including concrete and wood. There are four major categories of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Switchgear
In an electric power system, a switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levels and voltages rapidly escalated, making opening manually operated switches too dangerous for anything other than isolation of a de-energized circuit. Oil-filled switchgear equipment allows arc energy to be contained and safely controlled. By the early 20th century, a switchgear line-up would be a metal-enclosed structure with electrically operated switching elements using oil circuit breakers. Today, oil-filled equipment has largely been replaced by air-blast, vacuum, or SF6 equipmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfur Hexafluoride
Sulfur hexafluoride or sulphur hexafluoride (British spelling) is an inorganic compound with the formula SF6. It is a colorless, odorless, non- flammable, and non-toxic gas. has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas. is 23,500 times more potent than as a greenhouse gas but exists in relatively minor concentrations in the atmosphere. Its concentration in Earth's troposphere reached 10.63 parts per trillion (ppt) in 2021, rising at 0.39 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of gas contained in its med ...

Electrical Insulation
An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials—semiconductors and conductors—conduct electric current more easily. The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than semiconductors or conductors. The most common examples are non-metals. A perfect insulator does not exist because even insulators contain small numbers of mobile charges ( charge carriers) which can carry current. In addition, all insulators become electrically conductive when a sufficiently large voltage is applied that the electric field tears electrons away from the atoms. This is known as the breakdown voltage of an insulator. Some materials such as glass, paper and PTFE, which have high resistivity, are very good electrical insulators. A much larger class of materials, even though they may have lower bulk resistivit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
