One of the biggest challenges in cable fault diagnostics has always been the “blind zone” – the section at the very beginning of the cable where conventional TDR (Time Domain Reflectometry) methods fail to detect faults. In this zone, the reflection overlaps with the initial pulse, leaving defects invisible.
Step TDR technology
BAUR has introduced an innovative solution: the Step TDR technology. Instead of standard pulses, it uses high‑energy signals that penetrate deeper and deliver a clearer picture. With digital averaging and filtering, interference is eliminated, ensuring stable and reliable results even under demanding conditions.
Key Benefits
- Accurate detection of faults right at the cable start.
- Faster diagnostics and reduced network downtime.
- Intuitive interface that makes operation simple, even for less experienced technicians.
User story
The company Doha Cables in Qatar successfully applied the BAUR IRG 400 device with Step TDR technology to locate faults that were previously undetectable. The outcome was improved network availability and significantly shorter maintenance times.
Conclusion
The BAUR IRG 400 with Step TDR marks a major breakthrough in the industry. By solving the long‑standing problem of the blind zone, it makes faults at the very beginning of the cable visible – ensuring reliability and efficiency in both power and communication networks.
