Description

REB500 1MRB150052R12/D 1MRB150052R2 HE5009260001 500BU02/15030 distributed busbar protection belongs to the Relion protection and control product family. The product is designed to provide the core values of the IEC 61850 standard. REB500 supports different busbar protection philosophies. A distributed solution can be made by assigning each physical bay unit into the corresponding bay cubical. Alternatively, bay units can be integrated into centralized cubicles.

Applications

Large power plants: 110kV-500kV busbar protection for substations.

Power grid substations: Busbar differential and circuit breaker failure protection for urban core power grids.

Heavy industrial aluminum/steel plants: Busbar section monitoring for high-voltage power distribution systems.

Oil refineries: Automatic switching and protection of segmented busbars in large power supply centers.

Maintenance of bay protection functions

Before checking the bay protection functions, consider the possible effect of, for example, secondary

injection on other protection functions, such as the busbar and breaker failure protection functions.

Features and Benefit

GOOSE send for trip and remote trip enables Digital substation solutions where system design can be optimized, and copper wiring can be eliminated.

The Bay Units can now include Synchro check and Auto Recloser functionality for complete line protection solutions as an addition to the busbar protection.

Test Facility for testing trip circuits per feeder using the LHMI of the BU enables efficient testing of the BU and related wiring

The availability of the protection system has been increased due to the reduced need for a reboot after changing protection settings and the shortened start-up time of the system.

For enhanced utilization Multiple signal statuses it is now possible to assign multiple Signal to one LED on the LHMI

It is now possible to indicate Switchgear Position indication using multiple colors of one LED.

FAQ

Q1: Can versions REB500 1MRB150052R12/D 1MRB150052R2 HE5009260001 500BU02/15030 be used interchangeably?
A: Not recommended. Different suffixes indicate hardware/interface changes; mixing may cause recognition or bus issues.

Q2: If this REB500 1MRB150052R12/D 1MRB150052R2 HE5009260001 500BU02/15030 module fails, will protection fail?
A: Only the affected bay is lost, but that bus segment may be locked or limited and should be replaced.

Q3: Do I need to set address after replacing the REB500 1MRB150052R12/D 1MRB150052R2 HE5009260001 500BU02/15030 module?
A: Yes, each bay needs a unique address set via DIP switches or software.

Q4: Why is the ALARM light on the REB500 1MRB150052R12/D 1MRB150052R2 HE5009260001 500BU02/15030 module on?
A: It indicates self-test failure such as power fault, program error, or lost communication.

Q5: Does the REB500 1MRB150052R12/D 1MRB150052R2 HE5009260001 500BU02/15030 support non-ABB central units?
A: No. It only works with ABB REB500 central units (500CU).
