An integrated structure. The internal integrated dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, high resistance meter, DC high voltage source and other main components.
The instrument adopts digital technology, intelligent automatic measurement, equipped with a large screen 5.7 inch TFT pure color LCD touch display, Chinese menu, test results can be automatically stored and printed out, operators do not need professional training can be skilled use.

(1) The oil cup adopts a three-electrode structure, and the electrode spacing is 2mm, which can eliminate the influence of stray capacitance and leakage on the dielectric loss test results.
(2) The instrument adopts medium frequency induction heating and PID temperature control algorithm. The 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.
(3) The internal standard capacitor is SF6 charging three-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 is still guaranteed after a long time of use.
(4) Perfect protection function. When there is overvoltage, overcurrent, high voltage short circuit, the instrument can quickly cut off the high voltage, and send a warning message. A warning message is issued when the temperature sensor fails or is not connected. A limited temperature relay is provided in the medium frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay is released and the heating stops.
(5) Convenient setting of test parameters. The temperature ranges from 40 to 120 ° C, the AC voltage ranges from 200 to 2200V, and the DC voltage ranges from 0 to 500V.
(6) Using large screen TFT pure color LCD touch display, the display is clear. With a simple setup, the instrument can be tested automatically. And automatically store and print test results.
(7) With real-time clock, test date and time can be saved, displayed and printed with test results.
(8) Empty electrode cup calibration function. Measure the capacitance and dielectric loss factor of the empty electrode cup to judge the cleaning and assembly condition of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.
