Insulating Oil Volume Resistivity Tester

Main functions and features:

(1) Oil cups used in line with the national standard GB / T 5654-2007 three-electrode structure, the inter-electrode spacing of 2mm, can eliminate the stray capacitance and dielectric loss diarrhea drain on the test results.

(2) Instrument uses induction heating, PID temperature control algorithm. The heating with oil cup and heating body non-contact, uniform heating, fast, and easy control, strict control of the temperature within the preset temperature range of error.

(3) Internal standard capacitors SF6 inflatable three-electrode capacitance, the impact of the capacitor dielectric loss and electrical capacity from the ambient temperature, humidity, the instrument accuracy after prolonged use is still guaranteed.

(4) AC Test Power Supply with AC-DC-AC conversion, effectively prevent the mains voltage and frequency fluctuation on the dielectric loss test the accuracy of even the generator, the instrument can also run properly.

(5) Perfect protection. When overvoltage, overcurrent, short circuit when the high pressure, the instrument can be quickly cut off the pressure, and a warning message. When the temperature sensor fails or is not connected, warning message.

(6) Easy to set test parameters. Temperature setting range 0 ~ 125 ℃, the AC voltage setting range 500 ~ 2200V, DC voltage setting range 0 ~ 500V.

(7) Large-screen LCD display with backlight, clear display. Friendly interface, just follow the English menu prompt, enter the command, the instrument will automatically be tested. And automatically store and print test results.

(8) With real-time clock, test date and time can be saved with the test results, display and print.

(9) Empty cup electrode calibration. Empty cup measuring electrode capacitance and dielectric loss factor to determine the status of the cleaning and assembly empty cup electrode. Calibration data is automatically saved to facilitate the relative permittivity and dc resistivity accurate calculation.
