Section

F7fourkkRaO1fkXche3NxA

High-voltage cable partial discharge, circulation and temperature on-line monitoring system

ZY-PDM1000U-C UHF partial discharge on-line monitoring system consists of sensors, digital processing acquisition and communication unit, and background analysis software. It can realize on-line monitoring of partial discharge, temperature, and vibration of three-core cables. On-line monitoring of discharge, circulation, temperature, and vibration. The system can use CT to take power on the high-voltage side of the cable or directly connect to 220V.

[[[[产品参数, 参数]]]]
  ZY-PDM1000U-C high frequency partial discharge, partial discharge / temperature / circulation online monitoring system
  ZY-PDM1000U-C UHF partial discharge on-line monitoring system consists of sensors, digital processing acquisition and communication unit, and background analysis software. It can realize on-line monitoring of partial discharge, temperature, and vibration of three-core cables. On-line monitoring of discharge, circulation, temperature, and vibration. The system can use CT to take power on the high-voltage side of the cable or directly connect to 220V.
  The system can monitor the circulating current of the metal sheath of the cable, the current of the accidental return line, the high-frequency current signals generated by the partial discharge, the cable surface and joint temperature, the vibration of the intermediate and terminal joints, and realize line monitoring, so as to realize the early warning of the slow aging of the outer insulation of the cable, Cable outer sheath rapid damage alarm, accident return line theft alarm, connector failure temperature abnormal alarm, connector failure vibration alarm, main insulation high frequency defect manual identification alarm, etc.
