The instrument uses all-digital technology, all intelligent automatic measurement, equipped with large-screen color touch.
Touch screen, prompts in every step, test results can be printed out, operation.
Personnel can be proficient without professional training.
1. Highly automated, temperature rise and measurement dielectric loss can be completed at one time.
2. The oil cup adopts the three-electrode structure conforming to the national standard GB/T5654-2007, and the inter-electrode spacing is 2mm, which can eliminate the influence of stray capacitance and leakage on the dielectric loss test result.
3. The instrument adopts medium frequency induction heating and PID temperature control algorithm. The heating method has an oil cup and a heating body, advantages of uniform heating, fast speed, convenient control, etc., so that the temperature is strictly controlled at the preset temperature error.
4. Adopt advanced DSP and FFT technology to ensure data is stable, accurate and reliable.
5. The internal standard capacitor is SF6 gas-filled three-point capacitor. The dielectric loss and capacitance of the capacitor are not affected by the ring. The influence of temperature and humidity on the environment makes the accuracy of the instrument still guaranteed after long-term use.
6. Large-screen color touch screen, operation menu, convenient dialogue, simple and clear operation, one eye
7. With open cover high pressure, oil cup high and low voltage electrode short circuit and other warm tips, eliminate safety hazards, ensure the personal safety of the operator and the normal operation of the equipment.
8. With a real-time clock, test date, time can be saved, displayed, printed with the test results; equipment can display the ambient temperature, real-time detection of the test environment.
9. Automatically store measurement data, can store 100 sets of measurement data.
10. Empty electrode cup calibration function. The capacitance and dielectric loss factor of the empty electrode cup are measured to determine the cleaning and assembly of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculation of relative permittivity.
