ABB REF610C11LCLR

The ABB REF610C11LCLR is a feeder protection relay designed for use in medium-voltage (MV) distribution systems. It provides comprehensive protection, control, and monitoring functionalities for feeders, ensuring the safe and reliable operation of electrical networks.

Key Features:

• Overcurrent Protection: Protects against overcurrent conditions that could damage conductors and equipment.
• Earth Fault Protection: Detects and isolates earth faults, preventing personnel injuries and equipment damage.
• Reclosing: Automatically recloses the feeder after a fault to minimize downtime and restore power quickly.
• Metering: Measures and records electrical parameters like current, voltage, power, and energy consumption.
• Communication: Supports communication protocols like IEC 61850 and Modbus for integration into SCADA systems.
•  

Functionalities:

• Fault Detection and Isolation: Identifies and isolates various types of faults, including overcurrent, earth faults, and phase faults, preventing damage to the network and ensuring safety.
• Selective Fault Clearing: Selectively isolates faults to minimize the extent of service interruptions, limiting the impact on other parts of the network.
• Automatic Reclosing: Automatically recloses the feeder after a fault, restoring power quickly and minimizing downtime.
• Load Management: Manages feeder loads to prevent overloading and ensure stable operation of the network.
• Data Logging and Reporting: Records and reports electrical data, providing valuable insights for network operation, maintenance, and planning.
