Wire and Cable Testing Instruments
Used for measuring various power cables, high-frequency coaxial cables, local telephone cables, and buried wires laid evenly in pairs or more, with different cross-sections and media, to detect faults such as high and low resistance, short circuit, open circuit, broken wire, as well as high resistance leakage and high resistance flashover faults. It can also be used to measure cable length and the propagation speed of radio waves in cables. Portable: The host uses lithium battery power supply, lightweight, easy to carry, convenient for field testing and mine cable testing.
Main features of the cable fault tester:
1. Comprehensive functions, safe, rapid, and accurate fault testing. The instrument uses low-voltage pulse method and high-voltage flashover method for detection, can test various faults of cables, and can directly test flashover and high resistance faults of power cables without burning through. If equipped with an acoustic point detector, it can accurately determine the location of the fault point.
2. High testing accuracy. The instrument adopts 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 a menu display operation function, requiring no special training for operators.
3. Has waveform and parameter storage and recall functions. Uses non-volatile devices, so waveforms and data are not lost after power off.
4. Has dual-trace display function. The test waveform of the faulty cable can be compared with the normal waveform, which is beneficial for further judgment of the fault.
5. Has waveform expansion ratio function. Changing the waveform ratio can expand the waveform for accurate 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 the dual cursors, directly displaying the direct distance or relative distance between the fault point and the test point.
8. Has printing function. Print and archive the test results.
