Underground Cable Fault Locator/Cable Tester
Advantage
We are the first company in China who use industrial embedded computer platform system into cable fault locator. Lithium-power supply affords the convenience of field tests.
We are the first company in China who use 12.1 inch touch-screen and windows XP system.
The device adopt USB communication interface. The host can select 5 sampling frequency automatically between 6.25 MHz to 100MHz for the cable of different length.
The device can search the fault point and display the distance automatically, the movement of double cursor can be accurate to 0.15m. The waveform can be compressing or expanding freely. At the same time the system will display two waveforms randomly which is close to standard waveform for your reference.
The device saves total 40G waveforms and on-site wiring diagrams for your reference.
We developed smart modular sampler to replace the on-site wiring, the sampling is totally separated with high-voltage to ensure the safety of the operator.
We developed HP-G35 high frequency high voltage power supply (8.9Kg) to replace the testing transformer and operation box (65Kg).
Application
1.It can be used for test cable fault for different voltage levels, different sections and
different medium, including open circuit, short circuit, low resistance, high resistance
leakage, high resistance failure flashover.
2.It can be used for testing signal cable fault for railway station, airport.
3.It can be used for testing wave propagation speed of the cable which length is known.
4.It can be used for testing the cable route and depth.
