RDCD-Ⅱ/502 Cable Fault Pre-locator is used for power cable fault pre-location.🌟
➡️ Functional features:
✅12-inch industrial computer control and touch operation mode;
✅Windows operating system, a super cable management system, automatically generates test reports;
✅It has the functions of ranging and speed measurement;
✅Automatic continuous sampling, never missing any discharge waveform;
✅Methods: Low voltage pulse method, high voltage flashover method and multiple pulse method were used.
✅It has the function of mass test waveform storage: it can conveniently store the waveforms tested on the spot in the instrument according to the specified sequence, which can be called and observed at any time.
✅The measured fault point waveform and the full-length open circuit waveform of good phase can be displayed on the screen at the same time for the same screen comparison and superposition comparison. So that the fault distance can be judged more accurately.
✅Built-in li-polymer power supply: It can work continuously for more than 4 hours after being fully charged. Completely meet the field test requirements. It can also work with external AC power supply.
✅Eight pulse transmission and fault reflection signals are automatically displayed, and the full-length waveform of cable open circuit is displayed at the same time. So that the representation of fault characteristic waveform is extremely simple. There is only one high-resistance fault waveform, that is, the short-circuit fault waveform similar to the low-voltage pulse method, which automatically displays the fault distance and has no test blind area.
➡️Specifications and Technical Parameters:
✅Sampling rate: 60MHz, 120MHz, 240MHz；;
✅Pulse amplitude: 400Vpp
✅Pulse width: 0.1uS and 2uS
✅Measuring distance: the testing distance is 60km.
✅Reading resolution: 0.1m
✅The test accuracy of the system is less than 0.5m
✅Impulse coupler withstand voltage: 38kV DC
✅The reflected signal sent by the pulse coupler is automatically displayed, and the full-length waveform of the cable open circuit is displayed at the same time. So that the representation of fault characteristic waveform is extremely simple. There is only one high-resistance fault waveform, that is, the short-circuit fault waveform similar to the low-voltage pulse method, which automatically displays the fault distance and has no test blind area.
