Product Applications:
The CD9850 Cable Fault Tester can test all cables rated below 35KV for high resistance flashover, leakage faults, low resistance, short circuit faults, and open circuit faults.
Features:
1. Adopts the world's most advanced "secondary impulse method" testing technology. Any high resistance fault presents the simplest low voltage pulse short circuit fault waveform characteristics, making it extremely easy to interpret.
2. The automatic display of the transmitted pulse and fault reflection pulse in the secondary impulse method makes the representation of fault characteristic waveforms extremely simple. All high resistance fault waveforms have only one form, similar to the short circuit fault waveform in the low voltage pulse method.
3. The measured fault point waveform and the full-length open circuit waveform can be displayed simultaneously on the screen for same-screen comparison and overlay comparison, making the fault distance judgment more accurate.
4. Full Chinese menu and touch screen operation. Key definitions are simple and clear. The measurement method is simple and fast.
5. The fault detection success rate, test accuracy, and ease of testing are superior to any other detection equipment in China.
6. Touch LCD screen serves as the display terminal, with powerful data processing capabilities and a user-friendly display interface.
7. Equipped with extremely safe sampling high voltage protection measures. The test instrument operates reliably and safely in impulse high voltage environments.
8. Has a standard USB interface.
Other Notes:
The advanced secondary impulse method for testing cable faults has achieved remarkable results and is recognized worldwide.
The secondary impulse method simplifies the complex waveforms in the impulse high voltage flashover method into the simplest low voltage pulse short circuit fault waveform. Anyone can conveniently and accurately interpret the waveform, determine the fault distance, and achieve fast and accurate testing purposes.
Secondary Impulse Generator
The secondary impulse generator is used in conjunction with the CD9850 Cable Fault Tester to complete the secondary impulse testing function. It is the key technology and equipment for implementing the secondary impulse method.
