Why CableGuardian?

Award Winning Product.

CABLEGUARDIAN is an award winning product developed by VIPER INNOVATIONS, which brings together insulation resistance monitoring and conductor monitoring technologies into a single platform to enable continuous monitoring, fault diagnosis and location on live electrical systems.

Proactive Monitoring, Detection and Location.

It is the first product to offer proactive monitoring, detection and location of both insulator and conductor faults on live signalling power systems as specified in Network Rail specification NR/L2/SIGELP/27725.

Reduce Manual Fault-finding.

This unique product provides continuous monitoring of live signalling power supply systems at a cable section level without the need to power down the system, reducing the need for manual trackside fault-finding, reducing maintenance costs and ‘boots on ballast’.

No More Periodic Testing.

CableGuardian is the technological alternative to the 5 yearly manual cable testing requirement NR/L2/SIGELP/50000. Empowering the rail industry to move from the uncertainty of periodic testing, to a real-time condition based approach.

Product Features.

  • Monitors core to earth insulation resistance health at a sub-network cable section level
  • Monitors for core to core short and open circuit faults and locates to accuracy within 2% of cable length
  • Configurable for Tier 3, 2 & 1 monitoring i.a.w Network Rail NR/L2/SIGELP/27725
  • User friendly cloud hosted portal interface accessible via any device with a web browser
  • Input power can be from domestic supply or from line being monitored
  • All units are interchangeable – no master slave relationships for maximum redundancy
  • Robust communications options available including network agnostic cellular mobile, Ethernet and fibre optic.
  • Fully compatible with Network Rail Intelligent Infrastructure for Tier 3, 2 & 1 monitoring
  • 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
  • Analytics facilitate proactive rather than reactive maintenance
  • Permits a move from a frequency based inspection regime to one driven by actual asset condition and performance
  • Reducing risks to trackside personnel and the general public
  • Railway signalling power distribution systems
  • Mission critical IT (unearthed) electrical distribution systems

CableGuardian Enables Swift Repair and Avoids Costly Train Delays for Network Rail.

In this case study, discover how 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.

Once installed, Network Rail personnel commented on the ease with which the CableGuardian equipment could be installed and used for testing.
