ABB REF615 HBFDACADNAA1BCN1XE Feeder Protection Relay
The ABB REF615 HBFDACADNAA1BCN1XE is a dedicated feeder protection and control relay from ABB's Relion 615 series. This compact and versatile protection relay is engineered for protection, control, measurement and supervision of overhead lines and cable feeders in utility and industrial power distribution systems, including radial, looped and meshed distribution networks, with or without distributed power generation. The REF615 is designed to meet the demanding requirements of modern power distribution networks while providing comprehensive protection functionality in a compact form factor.
Protection and Control Functions
The REF615 HBFDACADNAA1BCN1XE provides an extensive range of protection and control functionality, operating either with sensors or conventional instrument transformers. The relay features directional and non-directional overcurrent protection, earth-fault protection, voltage protection, frequency protection, and power-based protection and measurement functionality. The extensive earth-fault protection portfolio includes unique multi-frequency admittance-based protection for higher sensitivity and selectivity, enabling reliable fault detection even in challenging network configurations. Optional advanced and fast fault location of short circuits and earth faults, arc protection, and high-speed outputs are available for enhanced system protection.
Communication and Integration
The REF615 supports IEC 61850 Editions 1 and 2, including HSR and PRP for network redundancy, GOOSE messaging for fast peer-to-peer communication, and IEC 61850-9-2 LE for sampled values, enabling less wiring and supervised communication. IEEE 1588 V2 provides high-accuracy time synchronization for maximum benefit of substation-level Ethernet communication. The relay also supports Modbus, DNP3, and IEC 60870-5-103 communication protocols, ensuring compatibility with a wide range of substation automation systems and SCADA platforms. This multi-protocol support enables seamless integration into both new and existing protection and control architectures.

Design and User Interface
The REF615 features a withdrawable plug-in unit design for swift installation and testing, reducing maintenance downtime and simplifying replacement procedures. The large graphical display shows customizable single-line diagrams, accessible either locally or through an easy-to-use web-browser-based HMI. This intuitive interface allows operators to monitor system status, view measurements, and configure protection settings from a remote location, enhancing operational efficiency and safety. The relay's compact dimensions and flexible mounting options facilitate integration into new and retrofit applications.
