Product description

Product Introduction
  Simulates various discharge phenomena inside GIS, suitable for experimental research and instrument testing of GIS partial discharge energized detection.
 
Main Features
  • High Fidelity: Designed according to the physical GIS, realistically simulating various partial discharge faults inside the GIS.
  • Good Integrity: Step-up transformer and coupling capacitors and other high-voltage equipment are built into the GIS.
  • Fault Simulation: Can simulate discharge types such as GIS tip, floating, air gap, particle, and surface, and multiple discharges can be combined.
  • Controllable Discharge: Discharge types can be arbitrarily selected, controlling the starting voltage, extinguishing voltage, and discharge intensity of each discharge signal.
  • Diverse Detection: Can provide a test platform for detection technologies such as pulse current, ultra-high frequency, ultrasonic, high frequency, and SF6 gas analysis.
  • Metrology Transfer: Built-in pulse current method related coupling and calibration unit, which can be detected synchronously.
  • Good Stability: Each discharge module can be reused, and the discharge characteristics are stable.
  • Easy Operation: The generation and disappearance of various faults can be directly controlled outside the device.
  • Diverse Basins: Basin-type insulators are available in various types, including fully shielded, bare basins, and casting ports.
  • Visualization: Built-in infrared video probe for easy observation of internal status and capturing discharge videos.
  • Built-in Sensors: Built-in ultra-high frequency sensor for easy comparison with the instrument under test.
