UTU Group In Finland supply OSM27 Reclosers To Vattenfall

Urho Tuominen Oy (UTU Group) have been awarded a contract to supply OSM27-200 reclosers to the Vattenfall power utility in Finland. Vattenfall are responsible for approximately 13% of Finland's distribution network.

Vattenfall is currently undertaking a distribution system reliability upgrade. The reclosers will be used to sectionalise long feeders and isolate faults without affecting upstream customers. It is expected that these steps will see a significant improvement in the utility's SAIDI and SAIFI indicators over the next 12 months.

Part of the contract involves integrating the reclosers into the Vattenfall SCADA network. The DNP3 protocol will be used to report by exception back to a GE iBox protocol converter. The iBox will then communicate to the SCADA master using the IEC 60870-5-101 polling protocol.
