The main functions and characteristics about this Insulation Oil Dielectric Loss Tester
1.Instrument by medium frequency induction heating, PID temperature control algorithm. The heating mode with oil cup with non-contact heating body, heat evenly, high speed, convenient control, make temperature strictly controlled within the preset temperature error range.
2.Internal standard capacitor for SF6 inflatable three pole type capacitor, the capacitance of the dielectric loss and capacitance is not affected by environmental temperature, humidity, The instrument accuracy after long time use is still guaranteed.
3.Perfect protection function. When over voltage, over current, high voltage short circuit, Instrument can quickly cut off the high pressure, and send out a warning message.. When the temperature sensor failure or not connected, the warning information. In the medium frequency induction heating furnace with finite temperature relay, When the temperature over 120 degrees, the relay release, stop heating.
4.Parameters setting is convenient. Temperature set range of 40 ~ 120 ℃,Ac voltage setting range200 ~ 2200 v,0 ~ 500 v dc voltage setting range.
5.Adopted the pure color TFT LCD touch screen display, show clear. Simply set, the instrument can automatically test. And automatic storage and print the test results.
6.Built-in real-time clock, the test date, time may be retained with the test results, display and print.
7.Empty cup electrode calibration function. Measure the empty cup electrode capacitance and dielectric loss factor, cleaning and assembly of electrode to determine empty cup. Calibration data is automatically saved for relative permittivity and precise calculation of dc resistivity.
8.Instrument RAM9 platform as the core, high precision, high speed.
