How to use the cable fault tester How to use the cable fault tester How to use the cable fault tester 1． Before the on-site fault test, you should first check whether the power of the instrument is sufficient. If the power is insufficient, you should connect an external power supply before the instrument can be used normally. 2. turn on“switch”, after the system starts, the instrument enters the Windows desktop system, and automatically enters the cable fault test system setting interface. 3. According to the type of the tested cable, the actual length and the nature of the fault, use the touch pen to click the relevant touch keys of the cable meter to perform initial parameter settings.
4. The parameters are set (default“Low pressure pulse method”), connect the red and black clips of the instrument test line to the faulty phase of the faulty cable under test and the other good phase or the ground wire of the cable respectively, click“sampling”key, the instrument automatically enters the data acquisition state, and the waveform is displayed on the screen at the same time. click again“sampling”key, the instrument will enter“continuous”sampling status. The operator can continuously adjust the amplitude and position of the waveform displayed on the screen“Position adjustment”and“Amplitude adjustment”knob.
Adjust until the waveform is easy to analyze, then click“Cancel sampling”Touch the key to stop sampling. 5. If set“high pressure flashover”, click“sampling”After pressing the key, the instrument enters“sampling”Waiting state, when the faulty cable is flashed with high voltage, it will automatically“sampling box”The acquired signal is displayed on the screen. and enter again“sampling”The waiting state is ready to collect the signal of the next high-voltage flash.
Adjusted during continuous high pressure flash sampling“Displacement adjustment”“Amplitude adjustment”knob, adjust until the waveform is easy to analyze, and then click“Cancel sampling” Touch the key to stop sampling, and then perform cursor operation to obtain the cable length from the fault point to the test end. The cable fault tester is a device that is rarely used, but once it is used, it is necessary to quickly use the device to find the fault point.
