HELPING TO KEEP THE TRAINS RUNNING ON TIME.
The CableGuardian system consists of multiple sensor units distributed across principal supply points (PSPs) and functional supply points (FSPs) each measuring multiple electrical parameters and communicating via a secure internet connection to a cloud-hosted data storage and analytics system. This system analyses the sensor data, providing continuous monitoring of the live system and indicating the location of any cable or conductor faults without the need to down-power the system, reducing the frequency and duration of trackside fault-finding campaigns.
CableGuardian provides monitoring at a cable section level, as defined in NR/L2/SIGELP/27725, breaking away from the traditional limitations of insulation monitoring devices which offer only a single insulation resistance measurement for the complete circuit or, at best, feeder level monitoring. Additionally CableGuardian’s capability for continuous monitoring of both the cable insulation and the copper or aluminium cores offers a technological alternative to the intrusive periodic cable testing requirements of NR/L2/SIGELP/50000.
