How to test the cable fault The test principle of the cable fault tester How to test the cable fault bigger. How to quickly and accurately recognize the fault point, and then solve the fault immediately, has become the top priority of each power supply organization. It will be more helpful for you to inquire about the testing principle of the cable fault detection device before installing the cable fault detector. Today, the cable fault tester expert will interpret the test principle of the cable fault tester for you.
The cable fault tester can test the high-resistance flashover, leakage fault, low-resistance, barrier fault and road robbery fault of various types of cables with 35KV partial voltage flow. Cable faults are likewise divided into two categories: low-resistance, open-circuit faults, and high-resistance faults. The instrument is known to work on the principle of radar ranging, sending a low-voltage pulse or a high-voltage pulse to the cable.
When the characteristic impedance does not match, the reflected wave will occur. The instrument records the transmitted waveform and the reflected waveform at a very high speed and displays it on the touch screen. The double cursors are stuck on the two characteristic inflection points of the waveform. . The instrument knows the incoming speed of the electric wave in the cable, and can calculate the difference between the fault point and the test point. The cable fault tester uses an opera-like structure and uses a touch screen operation interface. The effective buttons are displayed on the screen intuitively, and the user can operate it first-hand through the touch screen.
Equipped with waveform storage function, Wangyang's field test waveforms can be stored for recall and comparison on the same screen at any time. The test interface is simple and clear, the definition of the effect buttons is simple and clear, and the measurement method is simple and fast.
