HVDC Hellsjön-Grängesberg
Encyclopedia
The HVDC Hellsjön–Grängesberg is a test range from ABB
between Hellsjön and Grängesberg
to the testing of new components for HVDC. It consists of a 10 kilometer long overhead line, which was originally used as three-phase alternating current line and which is occasionally used for DC transmissions. The maximum transmission rate of the HVDC Hellsjön-Grängesberg is 3 megawatt, the operating voltage 10kV (symmetrical against earth). When it was first built in 1893, it was the first Swedish
power station to make use of the three-phase electric power
system which had been invented only a few years earlier by the Swedish inventor Jonas Wenström

power station to make use of the three-phase electric power
Three-phase electric power
Three-phase electric power is a common method of alternating-current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by grids worldwide to transfer power. It is also used to power large motors and other heavy loads...
