  *GB/T stands for “National recommended standards of China”.

  **DL/T stands for “Recommended standards of electric power industry of China”.

Key Features:

  Accurate simulation:The design is based on actual transformers, which accurately simulates the internal structures and the electrical characteristics of transformers.
  Fault simulation:Can simulate common types of faults including internal PD, winding failure, dampened bushing, and abnormal temperature.
  Comprehensive discharge simulation:Discharge type options including tip discharge, floating discharge, air-gap discharge, particle discharge, and creeping discharge.Each type of discharge can be simulated individually or combined.Discharge types, and discharge characteristics, such as inception voltage, extinction voltage, and intensity of discharge, can be controlled from the exterior of the device.
  Comprehensive testing options:Supports a wide range of testing methods: PD detection, oil analysis, thermal sensing, frequency response testing, and vibration analysis.
  Measurable testing:Preform pulse current PD test with built-in coupling and calibration instruments as reference measurement.
  Stable simulation:Discharge simulation cartridges generate stable discharge patterns, and have long use life.
  Basin insulator variety:Simulates various types of basin insulators: naked, metal flange insulated with pouring port, and fully insulated.
  Safety and reliable:Fully sealed oil tank and reliable grounding for safety.
  Viewable internal:See-through windows and built-in internal IR camera for the monitoring of internal conditions and discharges.
  Reference sensor:Built-in reference UHF, AE, and temperature sensors for comparing the measurements from other instruments.
