The ABB REB500BU (1KHL160006R0001H) is a bay unit designed for the REB500 distributed busbar protection system. It locally acquires and processes current and status signals, delivering fast and selective protection for substation busbars. This unit enhances fault isolation and system stability by operating independently within each bay.
Key Features
-
Decentralized protection: Each bay unit functions independently to improve fault isolation.
-
Fast fault response: Quickly detects faults and isolates affected sections to maintain stability.
-
Differential protection algorithms: Precisely discriminates faults across busbar zones.
-
Breaker failure logic: Includes redundancy for critical fault scenarios.
-
Check zone logic: Verifies fault location before initiating trip commands.
-
IEC 61850 integration: Fully supports modern substation automation and interoperability standards.
-
Flexible mounting: Suitable for both rack-mounted and panel-mounted installations.
-
Secure operation: Advanced cybersecurity ensures controlled access, logging, and account management.
-
Scalable architecture: Easily expanded by adding more bay units to existing systems.
