The main functions and features：
1, Grease cup used in line with the national standard GB/T5654-2007 of the three-electrode structure,interelectrode spacing 2mm,can eliminate the stray capacitance and leakage effects on dielectric loss test results.With oil drainage solenoid switch, can not remove the oil cup case emptying oil samples in oil cup, and flushing oil cup use sample oil.
2, The instrument adopts the medium frequency induction heating, PID temperature control algorithm. This heating method has the advantages of the oil cup and the heating body non-contact, even heating, fast speed, convenient control, strict control of the temperature in the temperature error within the preset range.
3, Internal standard capacitor of SF6 gas-filled three-electrode capacitance of the capacitor dielectric loss and electrical capacity independent of ambient temperature, humidity and other effects, the instrument accuracy is ensured even after prolonged use.
4, AC test power supply using AC-DC-AC conversion mode, effectively avoid the influence of voltage and frequency fluctuation on the accuracy of dielectric loss test, even if the generator, the instrument can also run properly.
5, Perfect protection functions. When there is an over voltage, over current, short-circuit high voltage, the instrument can be quickly cut off the pressure, and issued a warning. When the temperature sensor fails or is not connected, the warning message. In the medium frequency induction furnace equipped with a limited temperature relay, when the temperature exceeds 120 degrees, the relay releases, the heating is stopped.
6, Test parameter settings and convenient. Temperature setting range 0 to 125 degree celsius, the AC voltage setting range 500 to 2200V, DC voltage setting range 0 to 500V.
7, Using a large-screen LCD display with backlight, clear display. Friendly interface, simply follow the Chinese menu prompt, enter the command, the instrument can be automatically tested. And automatically store and print test results.
8, Built-in real-time clock, the test date, time may be retained with the test results, display and print.
9, Air electrode cup calibration function. Measurement of air electrode cup capacitance and dielectric loss factor, in order to determine air electrode cup cleaning and assembly condition. The calibration data is automatically saved, in order to facilitate the calculation of relative permittivity and DC resistivity.
