Product Introduction
This equipment used to test the distance between fault position to the measured transformer when aerial transmission line in short circuit or open circuit. It applies to the overhead transmission line with10KV and above, which with permanent single -phase earth fault or disconnection fault; make the tests for fault line in the substation. It can measure the exact distance, confirm the broken poles, convenient for maintainers to check the fault, shorten the repairing time.
This device only can be used if the measured line is power off. It is small in volume, easy to carry, with AC/DC battery, diagram and digital display, easy to operate

Product Feature And Application
1. Multi-functional, safe, fast speed and accurate. It uses the LV impulse method and HV flashover method to test, can test kinds of faults of the cable, especially can directly test the flashover and high resistance fault without burn through. If equipped with a sound locator, accurately detects the position of the fault point.
2. High precision, adopts high-speed sampling technique, A/D sampling speed is 100MHz, resolution is 1m, and detection blind area is 1m.
3. High degree of intelligence, test results auto-displayed by LCD.
4. Can store and review the waveform and parameters, the information will not lost after power off.
5. Dual display, which compares the measured waveform and normal waveform of the fault cable, benefits to further detection of the fault.
6. With the function of waveform expansion ratio, change the proportion of the waveform, and expand the waveform to test.
7. Directly display the direct distance or relative distance between the fault point and the measured point.
8. Can modify the speed according to different measured cables.
