Introduction
GOZ-DL-4A cable fault detecting system is a comprehensive set of cable fault detection system, capable of detecting of cable flashover failure, low resistance grounding, short circuit and cable break, poor contact test. If the instrument is equipped with acoustic pointing device, the exact location of the fault can be accurately determined. It is particularly suitable for testing various models, different levels of voltage power cables and communication cables.
Also called: Cable fault testing device, cable fault detecting equipment, high voltage cable fault detecting device, cable fault finding device
Feature
1. Fully functional, safe testing, fast, and accurate. The instrument uses low pressure pulse and high voltage flashover detection method which can directly test a variety of cable faults without burn on flashover and high impedance faults. If equipped with sound pointing instrument, the exact location of the point of failure can be determined.
2. High test accuracy. The instrument uses high speed data sampling technology, reading resolution 1m with high degree of intelligence. Test results are automatically displayed in the small data on the large-screen LCD, so determine fault is intuitive. And with a menu display operation, there is no need of specialized training for operating personnel.
3. It has a wave of open and parameter storage, transfer function. Using non-volatile unit, when the device shuts down, the waveform and data does no lose.
4. With dual trace display, the cable fault test waveforms can be compared with the normal waveform, which is beneficial for further failure determine.
5. Waveform proportion has extended functionality. By changes in the ratio of the waveform, the waveform can be extended with accurately test.
6. Control measurement cursor, the device can automatically search and stop at the inflection point.
7. Can arbitrarily change the position of the double cursor, then the relative distance between the fault point and the test point can be directly displayed.
8. Having print function, so the results of the test can be printed.
