Functional Description
The ABB REF615E-C integrates directional and non-directional protection functions, ensuring precise fault detection. Its compact 18.5 cm height and 8.5 cm width simplify cabinet integration, while the 1.08 kg weight reduces installation effort. Engineers benefit from advanced multi-frequency admittance-based earth-fault protection, which enhances sensitivity and selectivity. The relay supports both conventional instrument transformers and modern sensor technology, offering flexible system integration.
The ABB REF615E-C consumes less than 10W power and operates with auxiliary voltages ranging from 48–250V DC or 100–240V AC. Its withdrawable plug-in unit design allows quick installation, maintenance, and testing. The large graphical display supports customizable single-line diagrams, accessible locally or through a web-based HMI interface, improving user interaction and monitoring efficiency.
Applications and Compatibility
The ABB REF615E-C Feeder Protection Relay suits radial, looped, and meshed network configurations. Operators deploy it in utility substations, industrial plants, and distributed generation systems. Its IEC 61850 support with HSR and PRP redundancy ensures secure communication, while Modbus and DNP3 protocols expand compatibility with diverse automation networks.
