Oil dielectric loss volume resistivity tester

In the insulation preventive test of power equipment, it is required to regularly measure the insulation oil parameters of the power equipment. The measurement of oil dielectric loss volume resistivity is one of the important tasks. For a long time, the bridge method has been widely used for measurement, which is cumbersome to operate and the measurement accuracy is affected by many factors, resulting in large measurement errors. With the rapid development of electronic technology and the demand for small size, light weight, easy operation, fast measurement, and high accuracy measuring instruments in the power industry, our company has developed a high-precision integrated insulation oil dielectric loss factor and DC resistivity tester in China based on the national standard GB/T5564-2007/IEC 60247-2004 "Measurement of relative permittivity, dielectric loss factor, and DC resistivity of liquid insulation materials" and referring to relevant instruments at home and abroad.

Oil dielectric loss volume resistivity testerfeature

1. The measurement principle and highly digitized technology of the application enable fully automatic completion of processes such as temperature rise, temperature control, high-speed data sampling, calculation, display, printing, and storage

2. The oil cup adopts a three electrode structure that complies with the national standard GB/T5564-2007, with a spacing of 2mm between electrodes, which can eliminate the influence of stray capacitance and leakage current on the dielectric loss test results

3. The instrument adopts medium frequency induction heating, which has the advantages of non-contact heating between the oil cup and the heating element, uniform heating, fast speed, and easy control, so that the temperature is strictly controlled within the preset temperature error range

4. Contains standard capacitors, whose dielectric loss and capacitance are not affected by environmental temperature, humidity, etc., ensuring the accuracy of the instrument even after long-term use

5. Large screen color touch screen, convenient human-machine dialogue, simple and clear operation, easy to understand at a glance

6. Equipped with warm reminders such as opening the lid to break high voltage, oil cup high and low voltage electrode short circuit, etc., eliminating safety hazards, ensuring the personal safety of operators and the normal operation of equipment

7. Equipped with a real-time clock, the test date and time can be saved, displayed, and printed along with the test results

8. Automatic storage of measurement data, capable of storing 100 sets of measurement data, fast thermal printing speed

9. Equipped with empty electrode cup calibration function

10. Automatic saving of calibration data for accurate calculation of relative permittivity and DC resistivity
