Insulating Liquid Dielectric Loss ASTM D924 Automatic Power Factor Tester for Transformer Oil

Product Introduction:

General Descriptions:

The dielectric loss and resistivity tester of insulating oil is a high precision integrated testing instrument designed and manufactured on the basis of GB/T5654-2007″Measurement of relative capacitance, dielectric loss factor and DC resistivity of liquid insulating materials”. Mainly used for measuring dielectric loss factor and the DC resistivity of oil liquid and insulating medium, the internal integration of the main components of the dielectric loss cup, temperature controller, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, high voltage resistance tester, DC high voltage source. The instrument applies advanced measurement and control technology to complete the process of heating, temperature control, high speed data sampling, operation, display, printing and storage. Advanced measurement principles and high digital technology make your work easier.

The whole digital technology is used in the instrument, all intelligent automatic measurement, equipped with large screen color touch screen, full Chinese menu, every step has English hints, test results can be printed and output, operators can not be trained without professional training.

Characteristic of instrument

1.High automation, heating, measuring dielectric loss, and measuring resistivity can be completed at a time.

2.The three electrode type structure with an GB/T5654-2007 standard, inter electrode spacing 2mm, can eliminate stray capacitance and leakage effect on the dielectric loss test results.

3.The instrument uses 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 the stability, accuracy and reliability of the data

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. Correction 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.

11.Automatic emptying cup without disassembly, convenient and quick.
