Instrument characteristics
1. Highly automated, heating up, measuring dielectric loss, and measuring resistivity can be completed at one time;
2. The oil cup adopts a three-electrode structure that complies with the national standard GB/T5654-2007, and the distance between electrodes is 2mm, which can eliminate the influence of stray capacitance and leakage on the dielectric loss test results;
3. The instrument adopts intermediate frequency induction heating and PID temperature control algorithm. This heating method has the advantages of non-contact between the oil cup and the heating body, uniform heating, fast speed, convenient control, etc., so that the temperature is strictly controlled within the preset temperature error range.
4. Adopt advanced DSP and FFT technology to ensure stable, accurate and reliable data.
5. The internal standard capacitor is a SF6 gas-filled three-point pole capacitor. The dielectric loss and capacitance of the capacitor are not affected by ambient temperature, humidity, etc., so that the accuracy of the instrument can still be guaranteed after long-term use.
6. Large-screen color touch screen, Chinese operation menu, convenient dialogue, simple and clear operation, clear at a glance.
7. It has warm reminders such as opening the cover to break the high voltage and short circuit of the high and low voltage electrodes of the oil cup to eliminate safety hazards and ensure the personal safety of the operators and the normal operation of the equipment.
8. With its own real-time clock, the test date and time can be saved, displayed, and printed along with the test results; the device can display the ambient temperature to detect the test environment in real time.
9. Automatic storage of measurement data, 100 groups of measurement data can be stored.
10. Empty electrode cup calibration function. Measure the capacitance and dielectric loss factor of the empty electrode cup to judge the cleaning and assembly status of the empty electrode cup. The calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.
