Partial Discharge Detector For HV Switch Cabinet, Ring Network Cabinet and GIS

Product Introduction :

• Simultaneous interpreting PDsignals of almost all electrical equipment with different sensors.

  
  

• Provide time-domain waveform, PRPD, PRPS and other discharge patterns to realize the analysis of different discharge types.

  
  

• The human-computer interface facilitates the data management of different equipment, including the tracing of historical data change trend, horizontal and vertical data analysis, so as to realize 360° comprehensive diagnosis of the tested equipment.

  
  

• Built in ultrasonic sensor and transient ground voltage (hereinafter referred to as TEV) sensor, which can be externally connected with transformer, GIS, overhead line, cable and other special sensors.

  
  

• It is more convenient to use the non-invasive detection method than the traditional pulse PD detector because there is no need to cut off the power supply or apply high voltage source during the test.

  
  

• The test bandwidth range is 30kHz ~ 2.0GHz, which is applicable to the detection principle of various frequency bands.
