HVDC
A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages betwe ...
. 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 (AC) used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional n ...
