ABB's REL551 1MRK002480-AE is a high-performance line differential protection terminal. The following is a detailed description of its features:
Features:
Differential Protection: By comparing the currents flowing into and out of the protected line, accurate current differential protection is achieved. This allows for rapid detection of internal line faults, with high sensitivity and reliability, effectively preventing current anomalies caused by line faults.
Additional Protection: In addition to differential protection, it provides a variety of additional protection features, including phase and residual current protection, circuit breaker failure protection, and current circuit monitoring, providing comprehensive line protection and enhancing equipment operational safety.
Security: Password-required security measures prevent unauthorized changes to the device, ensuring stable and secure configuration.
Data Logging and Analysis: Supports logging and archiving of industrial data as text files. Users can specify triggers for data logging at specific times or under specific conditions, facilitating subsequent analysis of equipment operating data and aiding in troubleshooting and system optimization. Communication Function: Equipped with multiple communication interfaces, such as Ethernet, it facilitates data exchange with other devices, enabling remote monitoring, remote parameter setting, and remote fault diagnosis, improving system maintainability and management efficiency.
