Critical Mainline Station – Fault Finding with CableGuardian
Join the Revolution to Improve Signalling Resilience
CableGuardian is the only Network Rail approved cable monitoring system that offers adherance to Tier 3, Tier 2 & Tier 1 of the Network Rail standard NR/L2/SIGELP/27725 – Insulation Monitoring and Fault Location Systems for use on Signalling Power Systems.
- Tier 3 Approved
- Tier 2 Approved
- Tier 1 Approved
Proven Trackside Technology Since 2018: This advanced system has been proven in operation since August 2018, with multiple UK regions already benefitting from the technology and further installations scheduled across the network this year.
Key Benefits:
- Fewer boots on ballast fault finding and cable testing.
- Quickly and accurately locate cable faults and cable theft.
- User friendly web portal for fault diagnosis and location.
- Allows trending of insulation resistance and insulation capacitance at a cable section level.
- Technological alternative to the 5 yearly manual cable testing requirements.
CableGuardian helping passengers to arrive on time.
CableGuardian system avoids potential signalling power failure and delays to passengers without need of a possession.
In a recent intervention, CableGuardian has again shown its credentials as a key tool in the prevention of significant train disruption on the UK rail network by enabling staff to quickly identify a failing cable long before a fault occurred. This therefore avoided a signalling power failure and potentially thousands of delay minutes for the rail operator.
One recent installation site, located in the West of England, consists of 12 CableGuardian units configured in a Tier 2 arrangement with units installed simply in existing equipment buildings. This system continually monitors approximately 48 km of cables, switchgear, and other components along multiple feeders around a critical mainline station.
In addition to the permanently located CableGuardian units, the Delivery Unit also purchased 2 extra sets of hardware, incorporating split-core measurement coils, which enables the local Maintenance teams to rapidly install CableGuardian in locations which the Tier 2 monitoring system has indicated as being of some concern. This rapid deployment, as a portable roaming unit, is supported by the Viper Innovations Technical Support Team and creates a temporary Tier 1 system. This enables more localised data to be captured relating to the area of concern.
