Detection & Location of Electrical Faults
Faults happen. We help you find them – fast.
Quick, accurate fault detection that reduces downtime, improves safety, and helps you act with confidence.
Find Faults Faster with Insightful Diagnostics
Real-time insight and precise fault location
Electrical faults can stop operations — and every minute counts. We use advanced diagnostics to pinpoint issues quickly, reducing repair times, improving safety, and keeping critical systems online. Powered by Online TDR (Time Domain Reflectometry), including SSTDR, and smart analytics, our solutions give operators clarity and confidence when it matters most.
Advanced diagnostic method
Solution Overview & Technology Explained
Our online TDR technology, SSTDR (Spread Spectrum Time Domain Reflectometry), sits at the heart of our fault detection solutions. We send a low-energy, spread-spectrum signal along the cable to detect fault-related reflections and calculate their exact location, even while the system remains live and operational.
We integrate this advanced diagnostic capability within our CableGuardian solution for rail networks, combining continuous insulation monitoring with precise fault location. This gives us unparalleled visibility, enabling us to monitor cable health over time and pinpoint the exact location of a fault for rapid, targeted intervention.
Transforming Fault Management
Proven in rail and ready for more
In the rail sector, we have transformed fault management with CableGuardian, enabling faults to be detected and located remotely without trackside testing. This reduces downtime, improves safety for maintenance teams, and helps keep passenger services running reliably.
We extend the same benefits far beyond rail. Across aerospace, nuclear, renewables, and marine environments, where downtime is costly and safety critical, we provide precise fault detection and location. Whether identifying a subsea short circuit, a cable break in an aircraft system, or degradation within a nuclear facility, our technology gives operators the insight to act quickly and confidently.
Access System Health
Assess. Locate. Protect.
Electrical faults may be inevitable, but extended downtime does not have to be. We enable continuous assessment of system health and precise detection and location of faults, helping issues be addressed quickly and confidently.
Combined with our predictive analytics, these capabilities deliver a holistic approach to electrical integrity management, helping industries reduce costs, enhance safety, and extend asset life worldwide.

Case Study
Pinpointing cable faults in minutes, not days
Following repeated signalling power alarms, we used CableGuardian with SSTDR capability to pinpoint a developing fault to a specific cable section within minutes. This accuracy eliminated prolonged on-track testing, reduced workforce exposure, and enabled targeted repairs that restored full service quickly, demonstrating how rapid fault location dramatically cuts disruption.
FAQs
Understand how our intelligent diagnostics detect and locate electrical faults quickly to minimise downtime and improve safety.
How does Viper locate electrical faults accurately?
Using Spread Spectrum Time Domain Reflectometry (SSTDR), faults are detected and located by analysing signal reflections along cables.
Can faults be detected while systems are live?
Yes. SSTDR operates on energised systems, enabling fault detection without shutdown or service interruption.
What types of faults can be identified?
Short circuits, open circuits, impedance changes, and intermittent or transient faults can all be detected.
How does fault location reduce downtime?
Pinpoint accuracy allows maintenance teams to target the exact fault location, reducing investigation time and repair effort.
Is this technology limited to one sector?
No. While proven in rail, the same fault detection principles apply to aerospace, nuclear, marine, and industrial systems.
