YNYJS-H insulating oil dielectric loss and volume resistivity tester is a high-precision integrated testing instrument designed and manufactured according to GB/T5654-2007 "Measurement of relative permittivity, dielectric loss factor and DC resistivity of liquid insulating materials". It is mainly used to measure the dielectric loss factor and DC resistivity of liquid insulating media such as insulating oil. It integrates dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, and high resistance. Main components such as meter and DC high voltage source. , The instrument uses measurement and control technology to automatically complete the processes of heating, temperature control, high-speed data sampling, calculation, display, printing and storage. Measuring principle and highly digital technology make your work easier and more convenient.

YNYJS-H insulating oil dielectric loss and volume resistivity tester adopts all-digital technology inside, all intelligent automatic measurement, equipped with large-screen color touch screen, full Chinese menu, every step has Chinese prompts, test results can be printed out and operated The personnel can be used proficiently without training.

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. Using DSP and FFT technology to ensure stable, accurate and reliable data.

5. The internal standard capacitor is an SF6 gas-filled three-point pole capacitor. The dielectric loss and capacitance of this 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 tips such as opening the lid to break the high voltage and short circuit of the high and low voltage electrodes of the oil cup to eliminate potential safety hazards and ensure the personal safety of operators and the normal operation of 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 and 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 determine 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.
