Fault Finding with CableGuardian
The first platform to offer proactive monitoring, detection and location of both insulation and conductor faults on live low voltage ungrounded power distribution systems.
Developed in collaboration with Network Rail, CableGuardian supports the ambitions to reduce maintenance costs and time-related infrastructure failures, to reduce the frequency and duration of service affecting failures and to improve the overall asset management process.
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 signalling system and indicating the location of any cable or conductor faults without the need to down-power the signals, 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 is the technological alternative to the 5 yearly manual cable testing requirements in NR/L2/SIGELP/50000. Empowering the rail industry to move from the uncertainty of periodic electrical network testing, to a real- time condition based approach.
CableGuardian is the only Tier 1 cable monitoring system with full Network Rail product approval, for proactive monitoring, detection and location of both insulation and conductor faults on live Signalling Power Supply systems (SPS) as specified in Network Rail specification NR/L2/SIGELP/27725.
Euxton ASC
CableGuardian was used to quickly identify fault locations on the West Coast Main Line Signalling Power System at Euxton ASC, enabling a swift repair and avoidance of costly train delays.
