ET-2000A Oil Dielectric Loss Tester

The instrument adopts digital technology intelligent automatic measurement equipped with a large screen color touch screen, each step has tips test results can be printed the operator does not need to be skilled in the use of professional training.

Product characteristics

1. High automation heating measuring dielectric loss measuring resistivity can be completed once.

2. The three electrode type structure with an inter electrode spacing 2mm can eliminate stray capacitance and leakage effect on the dielectric loss test results.

3. Instrument using medium frequency induction heating PID temperature control algorithm. This heating mode has the advantages of non-contact oil cup and heating body uniform heating speed convenient control the temperature control in temperature within the preset range error.

4. Using advanced DSP and FFT technology to ensure data stability accurate and reliable.

5. Internal standard capacitor for the SF6 charging three pole capacitor dielectric loss and capacitance of the capacitor is not affected by ambient temperature humidity etc. so that the accuracy of the instrument after a long time to use is still guaranteed.

6. Large screen color touch screen man-machine dialogue convenient concise operation clear.

7. With the lid off the high voltage high voltage electrode cup short reminder eliminate safety hazards to ensure the normal operation of the safety of operating personnel and equipment.

8. With real-time clock test date time can be saved with the test results display print; equipment can display the ambient temperature real-time detection of the test environment.

9. Automatic storage measurement data can store 100 sets of measurement data.

10. Calibration function of empty electrode cup. The capacitance and dielectric loss factor of the empty electrode cup are measured to judge the cleaning and assembling condition of the empty electrode cup. The calibration data are saved automatically to facilitate the accurate calculation of relative capacitance and DC resistivity.
