Melo HVDC Back-to-back Station
The Melo HVDC Back-to-back station is the central part of the EHV-interconnection between Uruguay and Brazil, which is only possible by means of a frequency converter, as the frequency of the power grid in Uruguay is 50 Hz and that in Brazil is 60 Hz. The station, which is situated east of Melo, Uruguay, is interconnected by the San Carlos substation with a 283 kilometres long 500 kV line. It is capable of transferring 500 MW, and was built by AREVA in 31 months from 2009 to 2011. From the Melo station a 128 kilometres long 525 kV powerline, of which 65 km are situated in Uruguay, runs to a newly built 525 kV/230 kV substation close to the Candiota power station, which contains some harmonic filters.

High Voltage
High voltage electricity refers to electrical potential large enough to cause injury or damage. In certain industries, ''high voltage'' refers to voltage above a certain threshold. Equipment and conductors that carry high voltage warrant special safety requirements and procedures. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to produce electrical arcs, for ignition, in photomultiplier tubes, and in high-power amplifier vacuum tubes, as well as other industrial, military and scientific applications. Definition The numerical definition of depends on context. Two factors considered in classifying a voltage as high voltage are the possibility of causing a spark in air, and the danger of electric shock by contact or proximity. The International Electrotechnical Commission and its national counterparts (IET, IEEE, VDE, etc.) define ''high voltage'' as above 1000 V for alternating current, and at ...

Uruguay
Uruguay (; ), officially the Oriental Republic of Uruguay ( es, República Oriental del Uruguay), is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast; while bordering the Río de la Plata to the south and the Atlantic Ocean to the southeast. It is part of the Southern Cone region of South America. Uruguay covers an area of approximately and has a population of an estimated 3.4 million, of whom around 2 million live in the metropolitan area of its capital and largest city, Montevideo. The area that became Uruguay was first inhabited by groups of hunter–gatherers 13,000 years ago. The predominant tribe at the moment of the arrival of Europeans was the Charrúa people, when the Portuguese first established Colónia do Sacramento in 1680; Uruguay was colonized by Europeans late relative to neighboring countries. The Spanish founded Montevideo as a military stronghold in the early 18th century bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frequency Converter
A frequency changer or frequency converter is an electronic or electromechanical device that converts alternating current ( AC) of one frequency to alternating current of another frequency. The device may also change the voltage, but if it does, that is incidental to its principal purpose, since voltage conversion of alternating current is much easier to achieve than frequency conversion. Traditionally, these devices were electromechanical machines called a motor-generator set. Also devices with mercury arc rectifiers or vacuum tubes were in use. With the advent of solid state electronics, it has become possible to build completely electronic frequency changers. These devices usually consist of a rectifier stage (producing direct current) which is then inverted to produce AC of the desired frequency. The inverter may use thyristors, IGCTs or IGBTs. If voltage conversion is desired, a transformer will usually be included in either the AC input or output circuitry and this transf ...

Melo, Uruguay
Melo () is the capital city of the Cerro Largo Department of north-eastern Uruguay. As of the census of 2011, it is the ninth most populated city of the country. Location It is located at the center of the department, on the intersection of Route 7 with Route 8, south of Aceguá and the border with Brazil. Other primary roads to the city are Route 26 and Route 44. Geography The stream Arroyo Conventos (a tributary of Tacuarí River) flows by the west limits of the city. History It was founded on 27 June 1795 by Agustín de la Rosa, an officer to the Spanish Empire. It was named after Pedro Melo de Portugal, a Spanish colonial official of Portuguese royal ancestry. Given its proximity to some Portuguese colonies in Brazil, the "Melo Village" (in Spanish, "''Villa de Melo''"), as it was once named, was invaded by Portuguese forces in 1801, 1811, and 1816. With Uruguayan independence, Melo was officially declared capital of the department of Cerro Largo. In 1845, the city sq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Power Infrastructure In Uruguay
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, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...
