I. Overview

The JYT-C Oil Dielectric Loss and Resistivity Tester is a high-precision integrated testing instrument designed and manufactured in accordance with GB/T5654-2007 "Measurement of Relative Permittivity, Dielectric Dissipation Factor and DC Resistivity of Liquid Insulating Materials". It is mainly used for measuring the dielectric loss factor and DC resistivity of liquid insulating media such as insulating oil. The instrument integrates major components such as a dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, high resistance meter, and DC high voltage source. The instrument applies advanced measurement and control technology to fully automatically complete processes including heating, temperature control, high-speed data sampling, calculation, display, printing, and storage. The advanced measurement principles and highly digital technology make your work easier and more convenient.

The instrument adopts all-digital technology internally, with fully intelligent automatic measurement. It is equipped with a large color touch screen and a full Chinese menu, with Chinese prompts at every step. Test results can be printed out, and operators can use it proficiently without professional training.

II. Instrument Features

1. Highly automated: heating, dielectric loss measurement, and resistivity measurement can be completed in one run.

2. The oil cup adopts a three-electrode structure conforming to the national standard GB/T5654-2007, with an electrode gap of 2mm, which eliminates the influence of stray capacitance and leakage on dielectric loss test results.

3. The instrument uses medium-frequency induction heating and PID temperature control algorithm. This heating method has the advantages of non-contact between the oil cup and the heating element, uniform heating, fast speed, and convenient control, ensuring that the temperature is strictly controlled within the preset temperature error range.

4. Advanced DSP and FFT technologies are adopted to ensure stable, accurate, and reliable data.

5. The internal standard capacitor is an SF6 gas-filled three-electrode capacitor. The dielectric loss and capacitance of this capacitor are not affected by ambient temperature, humidity, etc., ensuring that the instrument's accuracy is maintained even after long-term use.

6. Large color touch screen with Chinese operation menu, convenient human-machine interaction, simple and clear operation, and easy to understand at a glance.

7. Equipped with safety reminders such as high voltage cutoff when the lid is opened, and short circuit of high and low voltage electrodes of the oil cup, eliminating safety hazards and ensuring the personal safety of operators and the normal operation of the equipment.

8. Built-in real-time clock: test date and time can be saved, displayed, and printed along with test results; the device can display ambient temperature and monitor the test environment in real time.

9. Automatically stores measurement data, capable of storing 100 sets of measurement data.

10. Empty electrode cup calibration function: measures the capacitance and dielectric loss factor of the empty electrode cup to judge the cleaning and assembly condition of the empty electrode cup. The calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.

11. The equipment has a high degree of automation and can automatically complete the cleaning of the oil cup.
