The HVDC Italy-Corsica-Sardinia (also called SACOI; Sardinia-Corsica-Italy) is used for the exchange of electric energy between Italy, Corsica and Sardinia.First used in 1965 as mono-polar line, today this takes the form of a bi-polar high voltage direct current ( HVDC) line. It consists of three overhead line sections: one on the Italian mainland with a length of 50 kilometers, one on Corsica with a length of 167 kilometers and one on Sardinia with a length of 87 kilometers. In addition to this, there are two submarine cable sections: 103 kilometers (between Italy and Corsica) and 15 kilometers (between Sardinia and Corsica).
Static inverters for this line, which can transfer a maximum power of 200 MW at a voltage of 200 kV are in use today. Until the 1990s mercuryMercury also called quicksilver is a chemical element in the periodic table that has the symbol Hg ( L. hydrargyrum and atomic number 80. A heavy, silvery, transition metal, mercury is one of only two elements that are liquid at room temperature (the othe steamIn physical chemistry and in engineering, steam refers to vaporized water. It is a pure, invisible gas (for mist see below), which at standard atmospheric pressure has a temperature of around 100 degrees celsius, and occupies about sixteen hundred times t electric rectifierA rectifier is one or more diodes arranged for converting alternating current (AC) to direct current (DC). When just one diode is used to rectify AC (by omitting the negative portion of the waveform) the difference between the term diode and the term rects were used, which have now been replaced by thyristorThe thyristor (also called a silicon-controlled rectifier or SCR) is a solid-state semiconductor device similar to a diode, with an extra terminal which is used to turn it on. Once turned on, the thyristor will remain on (conducting) as long as there is as. In 19921992 is a leap year starting on Wednesday. Events January January The Internet Society is formed. January 1 Boutros Boutros-Ghali of Egypt replaces Javier Perez de Cuellar of Peru as United Nations Secretary-General January 1 George H. Bush becomes the fi a second pole was taken in service, which can transfer 300MW at a voltage of 200kV. In contrast to most other installations for high voltage direct current transmission this system is a multipoint system making thus possible the energy exchange between several static inverter stations.
