    Feature:

    1.The system uses multi-level detection and frequency reduction technology to reduce the frequency of the discharge signal. At the same time, the high-speed AD conversion circuit is used to complete the digitization of the signal, and the reliability of the detected data is ensured through interference signal processing methods such as digital signal processing and adaptive filtering.

     

    2. By collecting different signals generated by partial discharges in different high-voltage equipment, the live state of the equipment can be quickly charged.

     

    3. The instrument can be installed and tested in the running state of the device, without any impact on the normal operation of the device.
