RED615 IEC NUMERICAL RELAY

Line differential protection and control RED615 IEC Numerical Relay is developed by ABB a recognized industrial manufacturer. RED615 IEC Numerical relay provides a compact and versatile solution for all types of utility and industrial power distribution systems. The need and demand for protection relays are increasing and numerical relays are getting more advance and robust. This device is a solid-state, two-end, line differential protection and control relay built to provide protection, measurement, and control, with a supervision function to supervise overhead line and cable feeders in multiple segments of utility and industrial power distribution networks. ABB numerical relays can also be used in radial, looped as well as meshed distribution networks for both with or without distributed generation. RED615 is also compatible with differential applications including an in-zone transformer. These relays communicate with substations over a fiber-optic link or through a galvanic pilot wire connection. Feeder protection includes two-end line differential communication.

Key benefits of RED615 IEC numerical relay

  • Phase-segregated two-end line differential protection (Selective unit protection) is available either with sensors or with conventional instrument transformers.
  • For fast and easy setup with tailoring capabilities, the device is provided with ready-made standard configurations, including line differential communication.
  • Extensive life-cycle services with withdrawable plug-in unit design for swift installation and testing
  • A large graphical display for customizable SLDs can be accessed locally as well with the help of an easy-to-use web-browser-based HMI which comes with Ring-type terminals for all connections

Key features of RED615 IEC numerical relay

  • The device offers Line differential protection with directional and non-directional overcurrent and earth-fault protection, voltage- and frequency-based protection, and measurement functionality
  • Line differential communication between substations either over a fiber-optic link or a galvanic pilot wire connection; is ideal for line differential applications with an in-zone transformer
  • Optional advanced and fast fault location of short circuits and earth faults
  • Comes with IEC 61850 edition 1 and 2 with HSR and PRP, GOOSE messaging and IEC 61850-9-2 LE is also provided for less wiring and supervised communication
  • IEEE 1588 V2 is provided for high accuracy with time synchronization & maximum benefit of Ethernet communication (substation-level). Supports Modbus, DNP3, and communication protocols.

ABB Numerical relay

ABB Numerical relays are built on the basis of microprocessors. A major difference between conventional electromechanical and static relays is in their wiring. Electromechanical and static relays come with fixed wiring and manual setting. Numeric relays, on the other hand, are programmable relays where the characteristics and behavior can be programmed. Most numerical relays are also multifunctional.

Product features

The device is integrated with a self-checking facility and is a low burden relay it helps in improving the accuracy. Other functionality includes timestamping, proper storage of historical data, and adaptive relaying schemes with fast fiber optical communication via substation LAN.
