Underground Cable Breakpoint Short Circuit Leakage Fault Location is a comprehensive set of equipment. It is used for testing open circuit, short circuit, ground fault, low resistance, high resistance flashover, and high resistance leakage faults in power cables, as well as precise testing of open and short circuit faults in coaxial communication cables and local telephone cables. It can also test cable path, burial depth, and radio wave speed measurement, verify cable length, and establish cable archives for routine maintenance management.
This instrument adopts multiple detection methods and applies the most advanced electronic technology achievements of the contemporary era. Using computer technology and microelectronics technology, it features high intelligence, complete functions, wide application range, accurate testing, and convenient use.
Features:
1. Complete functions, safe, rapid, and accurate fault testing. The instrument uses low-voltage pulse method and high-voltage flashover method for detection, capable of testing various cable faults. For flashover and high resistance faults in power cables, it can directly test without burning through. If equipped with an acoustic point locator, it can accurately determine the fault point location.
2. High testing accuracy. The instrument uses high-speed data sampling technology with a reading resolution of 1m. High intelligence. Test results are automatically displayed on a large-screen LCD in small text and data, making fault judgment intuitive. It also features menu-driven operation, requiring no special training for operators.
3. Waveform and parameter storage and recall functions. Using non-volatile devices, waveforms and data are not lost after power-off.
4. Dual-trace display function. It can compare the test waveform of the faulty cable with the normal waveform, facilitating further fault judgment.
5. Waveform expansion ratio function. By changing the waveform ratio, the waveform can be expanded for precise testing.
6. Control measurement cursor, can automatically search along the line and automatically stop at the inflection point of the fault waveform.
7. Can arbitrarily change the position of dual cursors, directly displaying the direct or relative distance between the fault point and the test point.
8. Printing function. Print and archive test results.
