Cable Fault Tester – a cable leakage detector @2022 for street lamp cable maintenance

Cable Fault Tester – A cable leakage tester for street lamp cable maintenance@2022Cable fault tester - a cable leakage tester suitable for street lamp cable maintenance @ 2022 DDB cable fault tester is mainly used for broken, short circuit, ground leakage faults of buried power cables with high and low voltages within 10KV (can be extended to 50kv) ( Positioning of the insulation resistance to the ground within 0.
5 megohms) and detection
of the depth and path direction of the buried cable.

It is suitable for street lamp cable maintenance, farmland watering cable fault repair, residential property and landscaping belt buried armor iron power cable, field power cable, highway, factory and mining enterprises, tower communication base station direct buried power supply cable fault troubleshooting and other industries
.

This instrument adopts advanced integrated circuit technology, cutting-edge calculation methods, simple circuit structure, high reliability and low false positive rate
.

DDB cable fault tester three-channel design: 1, length test: in the power off state can directly test the length of the cable disconnection, short circuit fault distance
.

2.
Anti-interference channel: high-performance filtering and anti-power frequency interference circuit are adopted, and the signal generator is used to locate the direct buried cable to the ground leakage position under the power off state, and the direction and depth
of the buried cable path are measured.

3.
Full-band channel: Use the probe rod to test the slight leakage fault position
of the directly buried low-voltage cable to the ground in the energized state.

It is a powerful tool
to shorten the fault finding time, improve work efficiency, and reduce the labor intensity of line maintenance personnel.
