Main functions and features
(1) The oil cup adopts a three electrode structure that complies with the national standard GB/T5564-2007, with a spacing of 2mm between electrodes, 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. This heating method has the advantages of non-contact between the oil cup and the heating element, uniform heating, fast speed, and easy control, which strictly controls the temperature within the preset temperature error range.
(3) The internal standard capacitor is an SF6 gas filled three-point polar capacitor, whose dielectric loss and capacitance are not affected by environmental temperature, humidity, etc., ensuring the accuracy of the instrument even after long-term use.
(4) Complete protection function. When there is overvoltage, overcurrent, or high-voltage short circuit, the instrument can quickly cut off the high voltage and issue a warning message. When the temperature sensor fails or is not connected, a warning message is issued. A temperature limiting relay is installed inside the medium frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay is released and the heating stops.
(5) Convenient setting of experimental parameters. The temperature setting range is 40-120 ºC, the AC voltage setting range is 200-2200V, and the DC voltage setting range is 0-500V.
(6) Adopting a large screen TFT pure color LCD touch display, the display is clear. With simple setup, the instrument can automatically perform testing. And automatically store and print test results.
(7) Equipped with a real-time clock, the test date and time can be saved, displayed, and printed along with the test results.
(8) Empty electrode cup calibration function. Measure the capacitance and dielectric loss factor of the empty electrode cup to determine its cleaning and assembly condition. Calibration data is automatically saved for accurate calculation of relative permittivity and DC resistivity.
(9) The instrument is based on the RAM9 platform, with high testing accuracy and fast speed.
