  • Light weight, small size, test safe operation, a complex dual-use, portable integrated structure.
  • With all-digital technology, the operation is intelligent and automatic;
  • With a large screen (240 * 180) LCD display;
  • Test results can be printed out;
  • Easy operation, the operators without professional training can be skilled use.
  • One heating part adopts the most advanced of the current high-frequency induction heating method, the heating oil-cup with non-contact with the heater, heating evenly, fast and convenient control and so on.
  • AC Test Power Supply with AC-DC-AC conversion means, effectively prevent the mains voltage and frequency fluctuations of the dielectric loss test the accuracy of the impact of even the generator, the instrument can also be run correctly.
  • Internal standard capacitors SF6 inflatable 3-pole capacitor, the capacitor dielectric loss and electrical capacity is not the ambient temperature, humidity, etc., to guarantee precision equipment in line even after prolonged use.
