Description
The GDUD-PBI Ultrasonic Flaw Detector is a professional, portable non-destructive testing (NDT) instrument tailored for power utilities. It uses advanced ultrasonic technology to detect internal cracks, voids, delaminations and material degradation in porcelain/composite insulators, HV bushings, CT/PT, transformer tanks and line hardware—without disassembly or shutdown.
Built on an embedded digital system and compliant with EN 12668-1, it integrates creep wave, angle beam and shear wave multi-mode testing. The high-sensitivity ultrasonic probe and auto-calibration ensure accurate coupling on curved surfaces. Rugged yet lightweight, it’s ideal for substation, transmission line and workshop NDT.

Advantages
Find Hidden Internal Defects
Detects micro-cracks and deep flaws invisible to visual inspection—prevents sudden failure & outage.
No Shutdown, No Disassembly
Portable NDT works on-site without de-energizing—saves 80% inspection time vs. traditional methods.
Power-Optimized Algorithms
Pre-set insulator/bushing test modes—field technicians master in 10 minutes.
Lab-Grade Accuracy On-Site
Auto-calibration + high-sensitivity probes deliver repeatable, reliable results in harsh conditions.
Long-Term Cost Savings
Early flaw detection extends asset life—cuts replacement costs and outage losses significantly.
FAQ
Q: Can it test both porcelain and composite insulators?
A: Yes. Multi-wave modes support porcelain, composite and polymer insulators.
Q: Does it work on curved bushing surfaces?
A: Yes. Auto probe calibration matches curvature for perfect coupling.
Q: What’s the smallest crack it can detect?
A: Detects micro-cracks ≥0.1mm with high-sensitivity probes.
Q: Is training required for field use?
A: Minimal. Pre-set power modes + one-knob operation—easy to learn.
Q: What’s included in the standard package?
A: Main unit, ultrasonic probes (creep/angle/shear), calibration block, Li-ion battery, charger, HDMI/TF cables, user manual, rugged carry case.
