GD6100C Automatic Precision Oil Dielectric Loss Tester,is used for measuring dielectric dissipation factor and DC resistivity of insulating oil and other insulating liquids. The instrument intergrates with test oil cell, temperature controller, temperature sensor, dielectric loss test bridge, AC test power, standard capacitor, high resistance meter, DC high voltage source and other major components.
II. Feature 1. The test cell adopts the three-electrode structure according to national standard GB/T5654-2007, with electrode spacing 2mm, which can eliminate the effects of the stray capacitance and leakage on dielectric loss test results. The device is equipped with the oil drainage solenoid switch, and we can empty the test cell without removing it and rinse it with the test sample oil. 2. The instrument adopts the medium frequency induction heating, PID temperature control algorithm. This heating method has the advantages of non-contact between the test cell and the heating body, uniform heating, fast speed, convenient control, and strictly control of the temperature within error range of the preset temperature. 3. Internal standard capacitor is SF6 gas-filled three-electrode capacitance, and its capacitor dielectric loss and electrical capacity are not affected by ambient temperature, humidity etc, so that the instrument accuracy can be ensured even after prolonged use. 4. AC test power supply uses AC-DC-AC conversion, which effectively prevents the fluctuations in mains voltage and frequency from affecting the dielectric loss measurement accuracy. Even a generator, the instrument can work properly. 5. Perfect protection function.When there is over voltage,over current or high-voltage short circuit, instruments can quickly cut off pressure, and issues a warning message. When the temperature of the sensor failure or not connected, the instrument will also issue a warning message. 6. There is a temperature limiting relay in the medium frequency induction heating furnace. When temperature above 120 degrees, the instrument frees the relay and stops heating. 7. Convenient test parameter setting.Temperature setting range 0~125 degree, AC voltage setting range 500~2200V, DC voltage setting range 0~500V. 8. Using of large-screen LCD display, with backlight and 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. 9. Built-in real-time clock, the test date and time may be saved, displayed and printed with the test results. 10. Calibration functions of cleaned dry cell. The measurement of dry cell's capacitance and dielectric loss factor can determine its cleaning and assembly conditions. The calibration data is automatically saved and so that it facilitates the calculation of relative permittivity and DC resistivity.
