Description

The ABB REF543 is a feeder terminal, which is a protective relay device used in medium-voltage electrical distribution systems. Here’s what I can tell you based on my search:

Function:

  • The ABB REF543 acts as an interface between the power line and the protection system.
  • It monitors electrical parameters like voltage and current to detect faults within the feeder circuit.
  • Based on its detected fault conditions, the REF543 can trip circuit breakers, isolating the faulty section and minimizing damage.

Key Features (based on available information):

  • Protection Functions: Likely offers protection against various fault types, potentially including:
    • Overcurrent and earth fault protection
    • Short circuit protection
  • Measurement: Measures electrical quantities like voltage, current, and power for monitoring purposes.
  • Communication: Might support communication protocols like IEC 61850, Modbus, or DNP3 for data exchange with supervisory control systems.
  • Sensor Connection: Connects to ABB Rogowski coils or voltage dividers for measuring current and voltage on the feeder [source needed].

Information Availability:

  • A single, dedicated datasheet for the REF543 might be difficult to find publicly.
