Performance Characteristics:

Applicable to various faults in power cables of different grades, cross-sections, media, and materials at 35KV and below, including: open circuit, short circuit, low resistance, high resistance leakage, and high resistance flashover faults.
Can be used with high-voltage equipment to implement traditional cable fault testing methods such as the low-voltage pulse method, impulse flashover method, and velocity measurement method.
Industrial-grade 8-inch color touchscreen LCD display, full Chinese operating software and user interface, sub-menu mode and text prompts for human-machine interaction.
Synchronous display of global and local waveforms for easy overall analysis and detailed adjustment.
Built-in power supply, allowing for long-term use in environments without power. Small size, light weight, easy to use, high testing accuracy; stable performance, no crashes, and safe high-voltage protection measures for signal acquisition.
Equipped with a standard USB interface for easy saving or retrieval of data and waveforms for re-analysis.
Provides multiple pulse widths for test signals, greatly improving the test success rate.
It can simultaneously display the measured fault point waveform and the full-length open-circuit waveform of the good phase on the screen for on-screen comparison and superimposed comparison, and can automatically determine the fault distance.
It can be equipped with a multi-pulse coupling unit to form a multi-pulse cable fault tester (GDBN-DC2000) using the three-pulse method and the eight-pulse method, which can integrate complex high-voltage flashover waveforms into easily interpretable low-voltage pulse waveforms.
