Konti-Skan 1 HVDC pole replacement
... The former Pole 1 of Konti-Skan was rated 250kV at 1000 amperes, but since new cables of higher rating have been installed the new pole will be rated 285kV at 1350 amperes, 380MW. Power is reversible. At both ends of the cable lengths (87km total) there are sections of overhead line of 52 and 10km. ...

Electric power system
An electric power system is a network of electrical components used to supply, transmit and use electric power. An example of an electric power system is the network that supplies a region's homes and industry with power—for sizable regions, this power system is known as the grid and can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centres to the load centres and the distribution system that feeds the power to nearby homes and industries. Smaller power systems are also found in industry, hospitals, commercial buildings and homes. The majority of these systems rely upon three-phase AC power—the standard for large-scale power transmission and distribution across the modern world. Specialised power systems that do not always rely upon three-phase AC power are found in aircraft, electric rail systems, ocean liners and automobiles.
