1. It can test all kinds of faults, such as open circuit fault, short circuit fault, high resistance flasover fault and high resistance leakage fault of various types of copper and aluminum core power cable, coaxial communication cable and local telephone cable with voltage grade below 35kV.
2. Have a variety of testing methods, such as low voltage pulse method, impact high voltage current sampling method, dc high voltage flashover method, etc.
3. The instrument is powered by high energy polymer rechargeable battery, and the sample interface is USB direct microcomputer power supply. Coupled with current sampling technology, so that the system truly achieve the operator and tester completely isolated from high voltage, strong anti-interference ability, at the same time to ensure the test reliability and man-machine safety.
4. The pre-sampling measuring unit adopts signal processing technology, and the test waveform features are clear and easy to distinguish, making cable fault analysis easier to master.
5. Wince operating system software, more user-friendly design, easy to operate.
6. Data processing technology of double track and screen comparison is helpful for you to conduct comparative analysis of waveform.
Technical Indicators
1. Range: 4m ~ 40Km
2. Ranging accuracy: the measurement error is less than 1m when the measurement range is less than 1Km
3. When the measurement range is greater than 1Km, the relative measurement error shall not be greater than 0.5%
4. Pulse amplitude: not less than 250V at 50Ω.
5. Pulse width: 0.2μs, 2μs, 4μs three.
6. Sampling frequency: 48MHz
7. System measurement error: the measurement result of the host is measured with the digital display synchronous fixed-point instrument, and the system error is 10cm.
8. Reading resolution: V/ 2F V wave propagation speed in the cable (m/μs) F sampling frequency (MHz). For example, the transmission speed of oil-immersed paper cable is V=160m/μs, and the reading resolution is 160/ (2×40) = 2m with f=40MHz sampling
9. The radio wave propagation speed of five kinds of cable media is preset: oil impregnated paper: 160m/μs; Crosslinked polyethylene: 172m/μs; Polyvinyl chloride: 184m/μs; Mining rubber-sheathed cable: 100m/μs; And other non-power cable radio wave speed Settings (optional media).
10. For other non-power cables, the propagation speed of the radio wave in the cable can be measured after the known length of the cable is input.
11. Sampling method: current sampling method.
12. Power supply: power frequency or in-machine polymer rechargeable battery.
