The 380 kV crossing Berlin is a 380 kV power line, mainly underground cables through the city of Berlin. The first section, put into service in 1977, consists of an overhead line with two circuits from Reuter power station. This was the first line to use plastic insulators. It runs next to a 110 kV line: these are the only overhead lines in the area of the former West Berlin. From there the line runs underground to the Berlin Center transformer station. This cable is water-cooled and laid in an accessible tunnel. Both Berlin Center transformer station and Reuter transformer station use totally enclosed SF6-insulated switchgear. This the oldest 380 kV-substation with SF6-technology in Germany. After reunification the Berlin 380 kV crossing was resumed in the western direction to Teufelsbruch transformer station and in the eastern direction to Friedrichshain transformer station. This line was laid in an accessible tunnel up to 30 m of depth, which has a small inspection railway. ...more on Wikipedia about "380 kV-crossing Berlin"

A cascade failure is described as when a system composed of interdependant elements is loaded at or near capacity, the system may suffer a complete failure if one (or more) of its elements is compromised. The term is frequently used in reference to large power grids. ...more on Wikipedia about "Cascade failure"

Directlink is a high voltage direct current transmission line between Mullumbimby and Bungalora in Australia. Directlink is a 59-km bipolar HVDC cable route, implemented for environmental protection reasons as underground cables. The system has three static inverters at each terminal, and three pairs of bipolar transmission cables. Each pair of cables operates at +/- 80 kV and transmits 60 MW, so the total rating of the project is 180 MW. HVDC was chosen for this project for reasons of low environmental impact of the transmission line, and the ability of the IGBT transistor converter stations at each end to accurately control both real and reactive power. Individual water-cooled IGBT modules are rated at 2.5 kV and 500 A, with multiple units connected in series to achieve the required voltage rating. ...more on Wikipedia about "Directlink"

HVDC or high-voltage, direct current electric power transmission systems contrast with the more common alternating-current systems as a means for the bulk transmission of electrical power. The modern form of HVDC transmission uses technology developed extensively in the 1930s in Sweden at ASEA. Early commercial installations include one in the USSR in 1951 between Moscow and Kashira, and a 10-20 MW system in Gotland, Sweden in 1954 . ...more on Wikipedia about "High-voltage direct current"
