Product details: REL561 1MRK002496-AC ABB line differential protection terminal
Line differential function:
Phase separation current differential: It can measure and evaluate the amplitude and phase angle of the current, achieving accurate current differential protection.
CT saturation detector: By using a built-in detector, the stability of the system is improved to prevent misoperation or refusal of operation caused by current transformer (CT) saturation.
Transmission delay compensation: It can continuously compensate for the delay during the transmission process, ensuring data synchronization at both ends.
Compensation for transmission tripping and charging current in digital communication channels: ensuring accurate transmission and execution of tripping signals during communication.
Line distance function:
Simultaneously measuring different phase to phase and phase to ground impedances within digital measuring components provides data support for fast and reliable fault detection.
Three zone protection: capable of conducting separate measurements based on different types of faults and each distance zone, ensuring the comprehensiveness and accuracy of protection.
Additional protection function:
Including phase overcurrent, residual current, and voltage function protection.
Circuit breaker fault protection, fuse fault, and current transformer circuit monitoring.
Fast cross regional communication of binary signals, supporting single pole or multi pole tripping.
Control function:
Command control: supports automatic reclosing and synchronization checks, including phase and power on checks.
Current differential protection: Real current differential protection is achieved by comparing the current entering and leaving the protected overhead line or cable.
