Forsmark is a village with 59 inhabitants on the east coast of Uppland , Sweden . It is best known as the location of the Forsmark Nuclear Power Plant .
10-593: Another noteworthy facility in Forsmark is the static inverter of HVDC Fenno-Skan , just west of the nuclear power plant. Because of the sensitive instruments for detecting local leaks of radioactivity, the nuclear power plant was the first place outside the Soviet Union where signs of the Chernobyl accident were detected on April 27, 1986. When workers at the plant were found to carry radioactive particles,
20-509: A maximum transmission rate of 550 megawatts (MW) at a voltage of 400 kV. It would be converted to become a bipole. The cable was manufactured part by ABB and part by Nexans . The total length of Fenno–Skan is 233 kilometres (145 mi), of which 200 kilometres (120 mi) is a submarine cable on the bottom of the Gulf of Bothnia . At the Swedish end the cable directly enters
30-521: A single crossbar carrying two conductors, which consist of a bundle of three or four ropes, on 5.5 metres (18 ft) long insulators, on the Finnish side. On the Swedish side, the towers carry the pole conductor (long insulators) and the neutral conductor (short insulators) from Finnböle to the Dannebo (Fenno-Skan 1) converter station. Fenno–Skan 2 crosses the traction current power line Tierp-Gävle and
40-702: Is a 33 kilometres (21 mi) long overhead line section from the coast in Finland at 61°4'37" N, 21°18'18" E to the static inverter station in Rauma, situated at 61°9′7″N 21°37′32″E. The ground electrode in Finland is situated near Rantala. From there an overhead electrode line on wooden poles runs first in Northeast, than in Northern direction until Ruokalho, where it meets the overhead line with two high voltage conductors. From Ruokalho to Rauma static inverter plant
50-578: Is the designation of the high voltage direct current transmission between Dannebo in Sweden and Rauma in Finland . Fenno–Skan was inaugurated in 1989. Taken into commercial operation in November 1989, Fenno–Skan was the longest submarine power cable in the world. It was also the first HVDC cable with 400 kV voltage and a rated power of 500 MW. The Fenno–Skan is a monopolar system with
60-464: The Dannebo static inverter plant near the Forsmark nuclear power station about 1 kilometre (0.62 mi) from the coast at 60°24'16"N 18°8'4"E. However, the electrode line from the static inverter plant to the ground electrode situated at 60°35'51"N 17°57'46"E is built as overhead line. It is a line with two conductors on wooden poles, which runs partly on its course past another powerline. There
70-544: The electrode line is fixed on a small crossbar above the high voltage conductors of Fenno–Skan and serves as ground conductor. In opposite to a normal ground conductor it is mounted on insulators equipped with surge arrestors. Fenno–Skan is operated by the Finnish and Swedish transmission system operators Fingrid and Svenska Kraftnät . Fenno–Skan 2 is the second cable of the Finland–Sweden submarine power connection. 800 MW, 500 kV subsea transmission connection
80-546: The origin of the leak was investigated and it eventually became clear that the contamination came from the atmosphere rather than from the Forsmark plant itself. Forsmark formerly had an ironworks producing oregrounds iron . 60°22′N 18°09′E / 60.367°N 18.150°E / 60.367; 18.150 This article about a location in Uppsala County , Sweden is a stub .

90-625: The parallel-running three phase 220 kV AC powerline Mehedeby-Gävle west of Mehedeby approximately at 60°28′45.2″N 17°14′11″E / 60.479222°N 17.23639°E / 60.479222; 17.23639 ( Fenno-Skan 2 crosses traction current power line Tierp-Gävle ) . This is the only crossing of an HVDC powerline and a single-phase AC powerline in the world and the only place where all kinds of electric transmission systems, three phase AC powerline, single phase AC powerline and HVDC come close together. Fenno–Skan 2 became fully operational on 16 December 2011. In February 2012
100-566: Was laid in 2011 by the cable laying ship SC Skagerrak , and it cost €150 million. The cable was manufactured by Nexans Norwegian plant in Halden . Two converter stations were supplied by ABB. Compare with Fenno–Skan 1, the Swedish converter station is located in Finnböle . The Fenno–Skan 2 cable is connected to the converter station by a 70 kilometres (43 mi) long DC overhead line. The pylons of this line are "classic HVDC pylons" with
