Product details: REL561 1MRK002496-AC ABB line differential protection terminal

Line differential protection: The application of current differential protection compares the current entering and leaving the protected overhead line or cable, providing phase separated true current differential protection for transmission, sub transmission, and distribution networks.

Digital System: This terminal is a digital system suitable for modern digital communication systems, including multiplexing and routing switching systems.

Main/Main Design: The current differential function adopts the main/main design, which evaluates each phase current at both ends separately using current amplitude and phase angle (separated vector comparison).

CT saturation detection: All currents are monitored separately by CT saturation detectors to minimize the requirements on current transformers and increase the stability of the affected stages at both ends in the event of CT saturation.

Transmission delay compensation: It can continuously compensate for the delay during the transmission process, ensuring data synchronization at both ends.

Communication interface: Supports multiple modern Ethernet, serial, and fieldbus protocols such as Ethernet/IP and Profinet, allowing it to function as a master, scanner, or controller in the network without any additional hardware.
