ZIV and BES deliver successful SAS project in Sierra Leone

ZIV has commissioned a protection, control and substation automation system for Sierra Leone´s Ministry of Energy. It has been a satisfactory overseas collaboration with British EPC, BES Group.

British Engineering Services (BES Group) specialises in the supply of electrical services and equipment to governments, utilities and industries worldwide. The company has experience in Africa.

The project involved the extension of the existing Kington Substation, located in Freetown: including a 161/33Kv Transformer, a 33Kv busbar and three feeders in 33Kv. ZIV supplied a protection panel for the power transformer, with the differential protection as well as backup protections and voltage regulator IEDs, an additional panel for control and metering functions of the power transformer, bay control units, meters and 33kV feeder panels.

It was completed with a Sequence of Events (SOE) and a Data Recording System (DRS) consisting of the substation automation units manufactured by ZIV. The engineering services included the configuration of the system, the integration with the data control centres of the end client, the electrical engineering of the protection and control part, as well as the factory acceptance tests and site testing.
