REF615 HBFHAEAGNGC6BNN11G Digital feeder protection and measurement control device

Protection Functions

• Provides directional and non – directional overcurrent protection, ground fault protection, voltage/frequency/power – based protection, etc., offering comprehensive protection for power system feeders.
  • Example: Overcurrent protection quickly responds to current overloads, while ground fault protection accurately detects ground faults and takes action.

Measurement Functions

• Real – time monitoring of electrical parameters such as current, voltage, and power, providing data support for performance evaluation and maintenance of power systems.
  • Example: Voltage parameters are monitored in real time to promptly identify abnormal voltage fluctuations.

Communication Protocols

• Supports IEC 61850 versions 1 and 2 (including HSR, PRP, GOOSE messaging, and IEC 61850 – 9 – 2 LE), IEEE 1588 V2, Modbus, DNP3, and IEC 60870 – 5 – 103, enabling data exchange with various devices or systems for remote monitoring and control.

Electrical Interfaces

• Data Electrical Interface: 9 – pin Sub – D jack connector, with pin definitions compliant with the Profibus DP protocol specification.
