Product Description


SF6-insulated discharge free test transformer system is mainly used for power frequency voltage insulation test of insulation materials, power products ect. If s also used as power supply for non partial discharge power frequency withstand test, current transformer, lightning arrester etc..


  1. With compact size and light weight( 40%-65% lighterthan same oil immersed test transformer in same level).
  2. Clean, no oil stain, no need maintainance .
  3. Not impacted by the harsh climate and environment, no need static to do test after movement.
  4. Insulation strength of gas-filled test transformer is obviously higher than the oil immersed test transformer, with minimal corona.
  5. PD level can be controlled within 5pC at rated output .


Main configuration including :
1. Power Noisy Filter
2. Console
3. Isolation Transformer
4. PD free SF6-insulated Test Transformer
5. Current Limit Resistor
6. Capacitive Voltage Divider
The capacity can be customized from 5kVA to 600kVA
The test voltage can be customized from 50kV 600kV
