Multifunctional Fault Tester for Power Cables

The cable fault detector is a comprehensive instrument for detecting cable faults. It can test high-resistance flashover faults, high and low resistance grounding, short circuits, cable breaks, poor contact, and other faults. It is suitable for measuring low-resistance, short-circuit, open-circuit break faults, as well as high-resistance leakage and high-resistance flashover faults in power cables of various cross-sections and dielectric materials (such as high-frequency coaxial cables, telephone cables, street light cables, and buried wires). It can automatically generate test reports.

Performance Features:

1. Controlled by a 7.6-inch tablet computer with touch operation;
2. Windows operating system, cable management system can automatically generate test reports;
3. Functions include distance measurement and speed measurement;
4. Fully automatic continuous sampling without missing any discharge waveform;
5. Testing methods: flashover sampling, low-voltage pulse sampling;

Technical Parameters:

1. 100MHz sampling frequency, resolution 0.5m (100m/us);
