CableGuardian Electrical Power Distribution Integrity Monitoring.
Proactive Monitoring, Detection and Location of Faults On Live Power Networks.
The first platform to offer proactive monitoring, detection and location of both insulator and conductor faults on live low voltage unearthed power distribution systems. CableGuardian encompasses proven technology with extensive industrial heritage in challenging environments to provide a distributed and intelligent cable infrastructure health monitoring system for various electrical industries.
CableGuardian is the only 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
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.
During a fault event alarms can be sent to users via configurable notification options, including the web portal, email, SMS text message and automated telephone voice message.
