CableGuardian 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.

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’.

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. CableGuardian is available for immediate order, Network Rail Product Certificate Number: PA05/06538

CableGuardian Condition Assessment

Assess Your System’s Condition Without Equipment Purchase Using Temporary Installation

The CableGuardian Asset Condition Assessment offers reliable insights into the health of power supply systems, supporting planned maintenance as part of a proactive asset management strategy. CableGuardian units (one per feeder) are temporarily installed at the PSP to conduct a Tier 2 insulation resistance (IR) condition assessment for each outgoing feeder, as well as for the PSP’s internal 650V electrical system. This allows for the identification of underperforming feeders or issues within the PSP, along with the detection of any existing IR faults in the system.

The Tier 2 assessment helps determine which feeder(s) may require further investigation. Additional CableGuardian units can then be deployed at trackside locations along the identified feeder(s) to provide Tier 1-level condition insights. Based on your requirements, accessibility, and available time, one or multiple units can be installed to subdivide the feeder(s) into smaller sections, allowing for increasingly detailed system condition analysis. This service facilitates condition-based equipment replacements, avoiding the need for blanket renewal of end-of-life assets.

For more information about CableGuardian Asset Condition Assessments, please refer to our Service Guide. If you are unsure whether a temporary or permanent installation best meets your needs, you can explore our Products & Services Comparison table below or contact us via our web form.

The CableGuardian Web Portal.

Results and information from the analytics package are made available via the CableGuardian web portal which is accessible from any internet connected device using the necessary secure login information. The portal has an intuitive user interface – results can be seen at a glance and historic trends of integrity data can be easily produced by the user. The portal is also designed to be fully compatible with the Network Rail Intelligent Infrastructure.

Fault alert & escalation process.

The CableGuardian system has configurable alarm and pre-alarm settings for the key parameters that are monitored, with the default settings being those contained within the Network Rail Standards. Alarm and pre-alarm settings are visually represented within the CableGuardian portal and are simultaneously sent to Network Rail’s Intelligent Infrastructure system using the current standard RS485 interface.

Additionally, Viper Innovations has worked collaboratively with Network Rail and has proven that this data can be directly passed from the CableGuardian Cloud to the Network Rail RADAR Cloud when this technology is released by Network Rail.

With CableGuardian you don’t have to wait for an alarm or even a pre-alarm in order to act and keep your Signalling Power System fully operational. It is possible to set alarm and pre-alarm values for each Sub-Network Section (this could be an entire feeder, part of a feeder, right down to an individual cable), which will also be visible within the portal.

By setting these Sub-Network Alarm Thresholds above the Network value it is possible to create an advanced warning of potential faults or long-term degradation long before they become an emergency.
