ABB DSSB140 48980001-P Battery Unit

Event recording

All events are stored with a resolution of 1 ms in the central unit and in the BUs.

System, protection and test events can be generated.

Protection events refer to the protected busbar and include the changes in the disconnector and breaker positions,

trips, etc. Test events are recorded during testing with the test signal generator.

System events describe the diagnostic and fault messages of the NBP system as a whole.

Frequency protection, including overfrequency, underfrequency and frequency rate-of-change protection,

is offered in IEDs with standard configurations H and J. 

The IED also incorporates optional three-pole multi-shot auto-reclose functions for overhead line feeders.

Customer benefits and savings 

• Risk Mitigation: Transfer of risk from client to ABB for coordinating design interface of all elements in the package to form a single product solution. 

• Reduced Client Resources: ABB being responsible for the scope of works described above reduces client manpower to engineer and manage the project. 

• Predictable Delivery & Cost Schedule: As a majority of the work is performed off site, 

the client is insulated from local labor shortages, environmental & industrial relations factors, granting fewer and shorter isolation possessions. 

• Reduced Site Resources: Comprehensive FAT can be performed before delivery reducing site commissioning requirements.

The data communication properties include the following communication standards: SPA bus, LON bus, IEC 60870-5-103.

IEC 61850 via SPA-ZC 400. Profibus DPV1 via SPA-ZC 302. 

DNP 3.0 and Modbus communication with higher level equipment. 

Further, the LON communication together with the PLC functions minimizes the need for hardwiring between the feeder terminals.

ABB’s comprehensive service offering ensures life cycle support for medium voltage products 

ranging from installation and commissioning, through condition monitoring and plant maintanace programs, 

to decommissioning and recycling. 

Our global network of service centers and experts help customers to optimize the performance of 

their equipment without compromizing on reliablity and safetyDescription.
