ABB REF610 Feeder Protection Relay

Description

Product Overview
The ABB REF610 is a highly specialized feeder protection relay with extensive application experience in the field of power distribution automation. As part of ABB’s Relion® family of protective relays, it integrates advanced power system protection technologies. Its core functionality includes overcurrent protection, grounding fault protection, phase discontinuity protection, and cable thermal overload protection, among others. It provides comprehensive protection for distribution networks, ensuring the safe and stable operation of power systems. In power distribution substations, the ABB REF610 serves as a critical protective device, monitoring and protecting feeder lines in real time. It quickly detects and isolates various faults such as overcurrent and grounding faults, minimizing fault impact and preventing system-wide outages.

Key Features and Benefits
The ABB REF610 offers diverse protection functions, including three-phase overcurrent protection (with low, high, and instantaneous settings), non-directional grounding fault protection (with low and high settings), phase discontinuity protection, three-phase cable thermal overload protection, and circuit breaker failure protection. It also provides arc protection when equipped with optional hardware. Its advanced protection algorithms ensure fast and accurate fault detection and isolation, minimizing damage to equipment and reducing power outage durations. The REF610 features multiple time-current characteristics, including nine inverse definite minimum time (IDMT) curves. Users can select the appropriate characteristic curve based on system requirements, enabling precise coordination of protection settings.
