I. Features:

1. Highly automatic, heating up, dielectric loss measurement, resistivity measurement can be completed at one time;

2. Oil cup with GB/T5654-2007 three-electrode structure, electrode spacing 2mm, can eliminate stray capacitance and leakage on dielectric loss test results;

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

4. Adopt advanced DSP and FFT technology to ensure data stability, accuracy and reliability.

5, the internal standard capacitor for SF6 inflatable three-point pole capacitor, the capacitance of the dielectric loss and capacitance is not affected by environmental temperature, humidity, so that the instrument accuracy is still guaranteed after a long time of use.

6, large screen color touch screen, Chinese operation menu, people's dialogue is convenient, simple and clear operation, at a glance.

7, with open cover break high pressure, oil cup high and low voltage electrode short circuit and other warm tips, eliminate hidden dangers, to ensure the safety of operators and normal operation of equipment.

8, with its own real-time clock, test date, time can be saved with the test results, display, print; The device can display real-time monitoring of the environment.

9, automatic storage of measurement data, can store 100 groups of measurement data.

10. Empty electrode cup calibration function. The electric capacity and dielectric loss factor of the empty electrode cup were measured to judge the cleaning and assembly status of the empty electrode cup. Calibration data are saved automatically to facilitate accurate calculation of relative permittivity and DC resistivity.

Two, technical indicators and use conditions
