What are the distinctive and unique features of the cable fault tester? The spectrograph deems appropriate and uses the low-voltage electronic pulse method and the high-voltage flashover method to carry out probe observation, which can test various faults of the cable. What are the distinctive and unique characteristics of the cable fault tester? correct. The spectrograph deems appropriate and uses the low-voltage electronic pulse method and the high-voltage flashover method to carry out probe observation, which can test various faults of the cable, and directly test the flashover and high resistance faults of the power cable without burning through.
If equipped with a sound point meter, the position of the fault point can be correctly calibrated. 2. High test precision. The spectrograph deems appropriate and uses high-speed numerical sample acquisition techniques, with a reading resolution of 1 m.
Deep intelligence. The final result of the test is semi-automatically displayed on the large-screen liquid crystal display screen with small scale and numerical value, and the fault diagnosis is intuitive. And it is equipped with some menus to reveal the operation functions, and no special training is required for the person who operates the position.
3. It has the functions of wave opening and parameter storage and adjustment. Use non-volatile reproductive devices as deemed appropriate, and the waveforms and values will not be lost after shutdown. 4, with double trace revealing function.
The test waveform of the faulty cable can be compared with the normal waveform implementation, which is helpful for further judgment of the fault. 5. It has the function of waveform expansion ratio. Change the waveform scale, expand the waveform to perform very accurate testing.
6. Controlling the survey cursor, it can search along the line semi-automatically, and stop semi-automatically at the inflection point of the fault waveform. 7. The position of the double cursors can be changed arbitrarily, and the direct distance or relative distance between the fault point and the test place can be directly revealed. 8. With printing function.
Print the final result of the test for record.
