Product brief
The YJD218 type dielectric loss and volume resistivity tester is a new generation high-precision integrated insulation oil dielectric loss factor and volume resistivity tester developed by our company based on the national standard GB/T5564-2007 "Measurement of relative permittivity, dielectric loss factor, and DC resistivity of liquid insulation materials" and with reference to relevant instruments at home and abroad. This instrument has the characteristics of small size, light weight, easy operation, fast measurement, and high accuracy measurement. It can be widely used in power plants, mines, petrochemicals, research institutes and other units, and is an ideal replacement product for existing products in the market.

1By applying advanced measurement principles and highly digital technology, the process of temperature rise, control, high-speed data sampling, calculation, display, printing, and storage can be fully automated;

2The oil cup is made in accordance with the national standardGB/T5654-2007Three electrode structure with inter electrode spacing2mmIt can eliminate the influence of stray capacitance and leakage current on the dielectric loss test results;

3The 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.

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

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

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

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

8Automatically store measurement data, capable of storage100Group measurement data, thermal printing speed is fast.

9Equipped with an empty electrode cup calibration function.

10Automatically save calibration data to facilitate accurate calculation of relative permittivity and DC resistivity.

11This product has an automatic oil cup structure, which allows for refueling testing or cleaning without removing the oil cup. After testing, the oil sample can be automatically drained.
