Research Summary

Line differential protection relays are critical devices for safeguarding power system lines, widely used in transmission, distribution, and substations. These relays monitor current differences at both ends of a line in real-time, enabling rapid detection and isolation of short circuits, overloads, and ground faults, ensuring system stability and equipment safety. Line differential protection relays feature high sensitivity, fast operation, and strong anti-interference capability, detecting and clearing faults within milliseconds to minimize damage and reduce outage impact. Their advanced digital control and communication interfaces support remote monitoring, data logging, and intelligent diagnostics, facilitating integration with modern power automation systems. With high reliability, precision, and rapid response, line differential protection relays play a crucial role in power system protection and fault management, providing a solid foundation for safe, stable, and efficient electricity supply.
