RBP D Busbar protection

ROCON Distributed Busbar protection system (BPS) includes central RBP D and peripheral units (RBP Dd or RFI D).

BPS is selective, reliable and fast protection system for busbar faults and breaker failers in MV, HV and EHV substations with practically all kind of busbar configurations. The protection is suitable for different types of current transformers - iron-core or linearized (Rogowski coil).  

The decentralized structure allows the protection to be optimally distributed according to the busbar configuration. The BPS is suitable for all kinds of short circuits in up to 4 zones busbar strucutre and 32 peripheral units.

For the two-way information exchange between the central and peripheral units, communication switches and high speed optical channels are used.
