Product Selling Points

 

  1. High automation: heating, dielectric loss measurement, and resistivity measurement can be completed in one operation.
  2. The three-electrode structure complies with GB/T5654-2007. With an inter-electrode spacing of 2 mm, it eliminates stray capacitance and leakage effects on dielectric loss test results.
  3. Medium-frequency induction heating with a PID temperature control algorithm. This heating method offers non-contact operation with an oil cup and heating body, uniform heating rate, convenient control, and temperature control within the preset range error.
  4. Advanced DSP and FFT technologies ensure data stability, accuracy, and reliability.
  5. Built-in reference capacitor for the SF6 charging three-pole capacitor. Dielectric loss and capacitance of the reference capacitor are not affected by ambient temperature, humidity, etc., ensuring continued measurement accuracy after long-term use.
  6. Large-screen color touch display with user-friendly man-machine interaction, enabling concise and clear operation.
  7. Safety interlock with high voltage disconnected when the lid is open, and a short-circuit reminder for the high-voltage electrode cup to eliminate safety hazards and protect both operators and equipment during operation.
  8. Real-time clock: test date and time are saved with the test results for on-screen display and printing. The equipment also displays ambient temperature and enables real-time detection of the test environment.
  9. Automatic data storage: up to 100 sets of measurement data can be stored.
  10. Empty electrode cup correction function. The capacitance and dielectric loss factor of the empty electrode cup are measured to assess cleaning and assembly conditions. Calibration data are saved automatically to support accurate calculation of relative capacitance and DC resistivity.
