Intelligent Multi-Pulse Method Cable Fault Tester
Darui Electric recommends:
Product Introduction:
KC-900S Intelligent Multi-Pulse Method Cable Fault Tester can test high, low-resistance faults in all cables up to 35KV, with strong adaptability. It adopts the "three-pulse method" multi-pulse sampling technology, which does not require manual waveform selection and can automatically determine distance. While the impulse high-voltage flashover occurs, it sends a group of eight fault test pulses with different delays, and one impulse high-voltage flashover can obtain typical eight groups of three-pulse waveforms. Any high-resistance fault waveform appears as a cable short-circuit fault waveform similar to that tested by the low-voltage pulse method. The software is well-designed, with full Chinese menu display and touch screen button operation, making it simple and fast, with quick and accurate test results; it has complete functions, and also includes the traditional low-voltage pulse method and impulse high-voltage flashover method; a large LCD screen serves as the display terminal, with powerful data processing functions and a friendly display interface, and a large data memory space; it has high-voltage sampling protection function, ensuring reliable operation in impulse high-voltage and strong electric field environments. It has a test waveform storage function, which can store a large number of field test waveforms for recall and observation at any time. It has a test waveform comparison function, which can display the measured fault point waveform and the full-length open-circuit waveform of the good phase simultaneously on the screen for same-screen comparison and waveform overlay comparison, making fault distance judgment more accurate. It has automatic waveform selection and automatic distance determination functions. Its sampling success rate and operational convenience far exceed those of ordinary multi-pulse cable fault testers (also called eight-pulse cable fault testers).
