Question: The cable fault tester has the following salient features Answer: 1. The function is complete, and the test fault is safe, fast and accurate. The instrument adopts the low-voltage pulse method and the high-voltage flashover method for detection, which can test various faults of the cable, and answer the questions of the power cable: the cable fault tester has the following salient features: 1. The function is complete, and the test fault is safe, fast and accurate. The instrument adopts low-voltage pulse method and high-voltage flashover method for detection, which can test various faults of cables, and directly test the flashover and high-resistance faults of power cables without burning through.
If equipped with a sound point meter, it can accurately determine the location of the fault point. 2. High test accuracy. The instrument adopts high-speed data sampling technology with a reading resolution of 1m. High degree of intelligence.
The test results are automatically displayed on the large-screen LCD screen with small size and data, and the fault diagnosis is intuitive. It is also equipped with a menu display operation function, which does not require special training for operators. 3. It has the functions of wave opening and parameter storage and recall.
Using non-volatile devices, the waveform and data are not easily lost after shutdown. 4, with dual trace display function. The test waveform of the faulty cable can be compared with the normal waveform, which is conducive to further judgment of the fault.
5. It has the function of waveform expansion ratio. Change the waveform scale and expand the waveform for accurate testing. 6. Control the measurement cursor, can automatically search along the line, and automatically stop at the inflection point of the fault waveform.
7. The position of the double cursor can be changed arbitrarily, and the direct distance or relative distance between the fault point and the test point can be directly displayed. 8. With printing function. Print and archive the test results.
