REL561 1MRK002496-AC line differential protection terminal

Product manual:

Main features:
Line differential protection: By comparing the current difference at both ends of the line,
Can accurately identify short circuits and ground faults, quickly isolate faults, and prevent fault propagation.
Multiple protection functions:
Overcurrent protection: detects overload or short circuit conditions in the circuit.
Grounding protection: specifically used for detecting and isolating grounding faults.
Distance protection: Determine and respond based on the distance of the fault occurrence.
High sensitivity and fast response: providing instant protective action,
Ensure the stability of the power system.
Communication and integration capabilities: Supports communication protocols such as IEC 61850 and Modbus,
It can be seamlessly integrated with other protective devices and automation systems.
Event recording and fault diagnosis: Record detailed fault information,
Including the time of occurrence, type and location of the fault, to assist in post event analysis and troubleshooting.
Flexible configuration: Protection parameters can be flexibly configured according to the needs of different power lines,
Meet various application scenarios.
Application scenarios:
High voltage transmission lines: providing precise differential protection for transmission lines,
Prevent faults from affecting other parts.
Substation and distribution network: protecting key equipment in substations and distribution networks,
Prevent the spread of faults.
Industrial power system: widely used in the power system of industrial facilities
