      JHZXPD-1 on-line monitoring system for partial discharge

       ??????
      recommendation index:
      UHF detection technology
      Sensor optimization placement technology
      SQL database analysis technology
      Strong anti-interference, good stability and high sensitivity
      • The system is mainly composed of UHF sensors, signal transmission, data collection devices and background data processing

      • The UHF discharge signal generated inside the equipment is monitored by the UHF sensor, transmitted to the processor through the radio frequency cable for amplification processing, and then entered the main server for analysis, display and storage. When an abnormal discharge signal is detected, an alarm is issued, and the first time Notify the supervisor
