HVDC
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating curre ...
. 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 10 kV (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
Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral ...
system which had been invented only a few years earlier by the Swedish inventor
Jonas Wenström.
