For 35kV and below different grades, different sections, different media and various materials of power cable faults, including: open circuit, short circuit, low resistance, high resistance leakage, high resistance flashover fault.
The low voltage pulse method, impact flashover method, three pulse method, multiple pulse method and speed measurement method can be combined with high voltage equipment to realize the traditional cable fault test.
Industrial 10.4 inch color touch LCD display, Chinese operating software and user interface, sub-menu and text prompts to achieve human-machine interaction.
The global waveform and local waveform are displayed synchronously, which is convenient for overall analysis and detailed adjustment.
The high resistance faults all show simple waveform characteristics similar to the low voltage pulse short circuit fault, which is easy to interpret.
When the multi-pulse method is used, 8 real waveforms are collected at the interface at the same time, which is more convenient for interpretation, lower test error and improve test accuracy.
Built-in power supply, can be used for a long time in the environment without power supply.
Industrial grade black safety protection box design, protection grade IP67, small size, light weight, easy to use, detection failure rate and high test accuracy.
Stable performance, no crash, signal acquisition high voltage protection measures safe.

The whole machine adopts industrial grade black safety protection box design, protection grade IP67, small and delicate, easy to carry; The human-machine interface is friendly, even if non-professional personnel operate, you can still quickly get familiar with and use, efficient and accurate to complete the cable fault test.
