Railway power supply in Norway

The traction power supply in Norway for the electric traction is based in Germany, Austria and Switzerland primarily on single-phase 15 kV and 16 ² / ₃   hertz. However, there are differences in the power supply.

Almost all of the energy for this is taken from the public three-phase network via converters . There are only two power plants that supply traction current. The Kjofossen power plant feeds the generated traction power directly into the overhead line, while the Hakavik hydropower plant supplies a 55 kV traction power network that feeds five substations. There are also traction current converters in two of these substations.

The Nygard hydroelectric power station used to generate traction power for the ore railway coming from Kiruna . The former traction power line to Sweden now serves as a 15 kV feed line for the overhead line.

The traction power network

Two single-phase 55 kV lines run from the Hakavik hydropower station: one to the Sande substation and one to the Sundhaugen substation. A 55 kV traction power line runs from the Sundhaugen switchgear station via the Skollenberg and Noragutu substations to Neslandsvatn. Another 55 kV line leads to the Asker substation, where it is taken north of Foss to the Ulvenen substation on the pylons of three-phase power lines and passes the three-phase substations Mjondalen, Langum and Lierbyen. In the section from the Ulvenen substation to shortly before Asker, it runs on its own masts and the rest of the way to the Asker substation, which is partially underground, is underground .

Decentralized converter plants

In Norway, almost all of the electrical energy for  railways operated with 15 kV, 16 ² ⁄ ₃  Hertz is provided by decentralized converter stations. In order to enable a quick replacement, these converters are usually mounted on railway carriages which are located in hall buildings along the railway line. Some of these converter plants are located in blind-ending tunnels, such as in Holmia and Hønefoss.
