ABB REF615C_D Relion 615 Feeder Protection Relay
The REF615C_D is a dedicated feeder protection and control relay from ABB’s Relion 615 series, designed for medium-voltage power distribution networks. It provides comprehensive protection, measurement, and supervision for overhead lines and cable feeders in radial, looped, or meshed system topologies. Featuring a withdrawable plug-in unit design, the relay allows fast installation, commissioning, and routine maintenance without disturbing panel wiring.
Protection Capabilities and Measurement Inputs
The relay incorporates protection algorithms to safeguard primary equipment against overcurrent, earth fault, phase unbalance, thermal overload, and breaker failure conditions. It accepts signal inputs from conventional current and voltage transformers (CTs/VTs) as well as modern sensor-based measurement devices, offering flexible adaptation to traditional and updated switchgear configurations.
Integrated control functions manage primary switching apparatus, including circuit breaker and disconnector control with built-in interlocking logic. Real-time system monitoring is supported by a large graphical LCD with LED status indicators, along with time-stamped event logs and disturbance recording for detailed fault analysis.
System Integration and Communication
Designed for substation automation and control system integration, the module supports standard communication protocols, including IEC 61850, Modbus, DNP3, and IEC 60870-5-103. Built to withstand demanding electrical environments, it meets IEC, ANSI, and CE standards and operates within an ambient temperature range of -40 deg C to +70 deg C.
