Feeder protection relay REF615R

The REF615R is designed to provide customers with a 19” rack mount version of the Relion series REF615 feeder relay, as well as an easy, cost-effective upgrade of the DPU2000R.

The REF615R features the same rear terminal block layout as the existing relay, reducing the installation time while ensuring that the existing wiring and its terminal connectors can be connected without the need for any modifications.

It also offers an optional cable fault detection (CFD) feature for real-time detection and notification of short duration, high current feeder faults where the substation breaker does not operate. Knowledge of fuse-operated outages before first customer call and of incipient underground (insulation) and overhead (vegetation) faults without outage is possible with CFD.

REF615R is a member of ABB’s Relion® family and a part of its 615 protection and control product series. The 615 series has been designed to unleash the full potential of the IEC61850 standard for communication and interoperability of substation devices including fast, horizontal relay-to-relay (GOOSE) communications for cost-effective, reliable and high-speed control schemes. The relay also supports DNP 3.0 and Modbus® protocols.

 
Why ABB?
Four major ease of replacement benefits for ANSI and IEC DPU2000R users:

  • Same form and fit eliminates panel cutting or rack repositioning
  • Wire-alike I/O and CT/VT connections greatly reduce drawing modification time
  • Comparable protection and control plus more included
  • Near SCADA-alike for DNP3.0 points & Modbus registers
