Manufacture 1KV~35KV set of cable fault detector
Wuhan Dewei Electrical Test Equipment Co.,Ltd is able to supply variety kinds of test machine for transformers. And our integrated test equipment bench combines single functions into one machine to meet our customers' different test requirement.
This cable fault location test systems is able to meet requirement of different capacity of electric cable set. We'll provide design project with your detail requests.
Product description:
DWDL-2 cable fault test system including cable fault test mainframe, route signal generator, route signal receiver, fault locater and some other parts. The mainframe use Windows operation interface and be able to test variety kinds of cable faults, also open-circuit & short-circuit fault of coaxial communication cables and local cable.
Features:
1. Multi functional, safe, fast speed and accurate. It uses LV impulse method and HV flashover method to test, can test kinds of fault of the cable, if equipped with sound locator, can accurately the position of the fault point.
2. High precision, adopts high-speed sampling technique, A/D sampling speed is 100MHz, resolution is 1m, 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, these information will not loss after power off.
5. Dual display, compare the measured waveform and normal waveform of the fault cable, benefit to further detection of the fault.
6. With function of wave form expansion ratio, change the proportion of the waveform, expand the waveform to test.
7. Directly display the direct distance or relative distance between fault point and measured point.
8. Can modify the speed according different measured cable.
9. Portable design , small in volume , with rechargeable battery, easy to carry and operate.
