Fault location and monitoring system for tunnel leaky cables
Swiftly address faults, ensuring comprehensive and reliable railway communication support.
System Architecture Product Application BACK
System Architecture

The LRMS tunnel leakage cable fault location and monitoring system uses time-domain reflection analysis to precisely locate faults in leakage cables and feeders, enabling real-time monitoring and instant fault reporting. It integrates self-checking, three-level alarms, long-distance high-precision detection, and remote monitoring. By master-slave collaboration, it extends detection range, enhances accuracy, and responds swiftly to faults, ensuring comprehensive and reliable railway communication.

1. Using radar time-domain reflection detection technology to accurately monitor the return loss and standing wave ratio at a certain point of the cable leakage;
2. Can share transmission channels with fiber optic repeater systems without occupying additional fiber optic cable resources;
3. The longest monitoring distance is greater than 2 kilometers, and the monitoring accuracy is less than 1 meter;
4. Equipment self checking function, active fault alarm;
5. Built in lightning protection and surge protection, suitable for harsh electrified railway environments.
