product description:
REF615 IEC Feeder protection and measurement and control devices are specialized feeder protection and measurement and control devices designed to protect, control, measure and monitor public and industrial distribution systems. The REF615 can be adapted to both neutral ungrounded and neutral resistance or impedance grounded networks. In addition, the REF611 can also be used for ring mesh distribution networks or radiation network protection, using the device’s advanced interstation communication capabilities. The protected grid includes multiple feeds and distributed generation.
The REF615 IEC feedback protection and measurement unit is available in 12 standard configurations for common feeder protection and measurement applications. The REF611 features support for the substation IEC61850 communication standard, Parallel Redundancy Protocol (PRP), and High Availability Seamless Redundancy Protocol (HSR), where the IEC61850 communication standard includes IEC 61850-9-2 LE. The relay also supports DNP3, IEC 60870-5-103 and Modbus® protocols. The Profitbus DPV1 protocol is supported through the SPA-ZC 302 protocol adapter.
The REF611 IEC feedback protection and measurement and control unit is a member of the 615 product family in ABB’s Relion® product family.
