FB18 Cable Fault Tester
It integrates fault location, path detection, high-voltage signal generation, and precise location for resolving various faults on power cables up to 35kV.
Highlights


FB11 consists of four parts.
Cable Fault Distance Detection Host- One-click distance measurement
- It can automatically locate the distance to the fault point , reducing the dependence on operator experience, making fault distance measurement easy
- 8-inch color LCD touch screen , which displays waveforms clearly and allows for intuitive and convenient operation
- The fault waveform can be compared and superimposed with the intact waveform on the same screen, and the fault distance can be intelligently judged with clear results
- Equipped with high-voltage protection measures, it will not crash or be damaged in high-voltage environments, and the built-in power supply supports operation in environments without mains power.
PTR50 Intelligent Locator – Synchronous acoustic and magnetic positioning
- It has the digital size display of sound waves, electromagnetic waves and the distance prompt of the fault point (0-25 meters), which guides the operator to approach the fault point like a “navigator”
- Equipped with anti-interference military headphones and combined with multiple filtering bands, it can effectively capture real discharge signals in complex environments.
- Real-time display of audio waveforms and step voltage waveforms, which can assist in judgment by analyzing waveform features, avoiding fatigue and misjudgment caused by relying solely on human hearing
T6000 Cable Path Finder – Fully digital technology for cable path identification
- Fully digital electromagnetic induction: advanced technology that can easily solve the problem of path detection for metallic dead short circuit faults
- Provides multiple frequencies and output modes (induction, direct connection, clamp) to adapt to various complex site conditions
- The transmitter can last for more than 12 hours in energy-saving mode , meeting the needs of long-term field work
Battery-integrated high-voltage signal generator
- The high-voltage power supply, pulse capacitor, discharge mechanism, etc. are scientifically integrated into a closed box, safe and stable
- Supports continuous pulse, DC, single pulse and other modes, adapting to different test methods

Real Experiences with TFN Testers
Robert K.
“This device is extremely versatile — it can measure cable length, locate breaks or short circuits, trace cable routes, and even detect leakage. The precision is excellent, and it makes fault finding so much easier”
Sarah L.
“I really like how easy it is to use. The results are accurate and consistent, and it helped us locate faults much faster than before. A great tool for everyday maintenance work.”
