ABB RED615 Line Differential Protection And Control

Description:

The RED615 is a compact and versatile relay designed for utility and industrial power distribution systems. It integrates protection, control, monitoring, and supervision into a single unit, suitable for radial, looped, and meshed distribution networks, with or without distributed generation. It is also capable of line differential applications with an in-zone transformer.

Features:

• Line Differential Protection: Provides phase-segregated two-end line differential protection for selective unit protection.
• Communication: Facilitates line differential communication between substations via fiber-optic link or galvanic pilot wire connection.
• Protection Functions:
  • Directional or non-directional overcurrent and earth-fault protection
  • Voltage- and frequency-based protection
  • Measurement functionality
• Advanced Fault Location: Optional advanced and fast fault location for short circuits and earth faults.
• Standards Compliance: Supports IEC 61850 Editions 1 and 2, including HSR and PRP, GOOSE messaging, and IEC 61850-9-2 LE for minimized wiring and supervised communication.
• Time Synchronization: IEEE 1588 V2 for high-accuracy time synchronization.
• Communication Protocols: Supports Modbus, DNP3, and IEC 60870-5-103 communication protocols.
