Oppgradering av Ulven transformatorstasjon

Omexom in Norway has been awarded a contract by Hafslund Nett, the electricity operator in Norway, to upgrade the Ulven substation located in central Oslo. The need for the upgrade is driven by increasing short-circuit levels in the regional network, which have compromised the short-circuit security of the current plant.

Overhaling av 47 kV system

The scope of the project involves a complete overhaul of the 47 kV system across 14 switch fields, including the replacement of switches in three capacitor battery switches. Additionally, the project will entail dismantling materials in six non-operational switching fields, replacing switches in open 11 kV switching systems, and dismantling 11 kV systems no longer in operation. Further work includes disassembling compressed air systems, performing wall penetrations, and executing necessary extensions and adaptations to both the control system and the grounding of new plant parts.

Statnett oppgraderer egne felt

It is important to note that some of the fields at the Ulven plant are owned by Statnett, who are responsible for conducting the upgrade work on these specific fields themselves. The project, which has just commenced, is scheduled for completion in November 2020.
