Transformer Oil Tan delta resistivity Tester

YJS-H Transformer Oil Tan delta resistivity Tester is used for measuring dielectric loss factor and DC resistivity of liquid insulating medium such as insulating oil. An integrated structure. The internal integrated dielectric loss oil cup, temperature controller, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, high resistance meter, DC high voltage source, and other main components. Inside the instrument adopts full digital technology, all intelligent automatic measurements, equipped with a large screen 5.7 inch TFT pure color LCD touch display, test results can be automatically stored and printed out, and operators do not need professional training can be skilled use.

It adopts medium-frequency induction heating and PID temperature control algorithms. The heating method has the advantages of non-contact between the oil cup and the heating body, uniform heating, fast speed, convenient control, etc., so that the temperature is strictly controlled within the preset temperature error range.

YJS-H Transformer Oil Tan delta resistivity Tester parameters 

Transformer Oil Dielectric Loss Analyzer features: 

1. The oil cup adopts the three-electrode structure by the national standard GB/T5654-2007, and the electrode spacing is 2mm, which can eliminate the influence of stray capacitance and leakage on the dielectric loss test results.
2. The instrument adopts medium-frequency induction heating and PID temperature control algorithms. The heating method has the advantages of non-contact between the oil cup and the heating body, uniform heating, fast speed, and easy control so that the temperature is strictly controlled within the preset temperature error range.
3. The internal standard capacitor is an SF6 inflatable three-pole capacitor. The dielectric loss and capacitance of the capacitor are not affected by the ambient temperature and humidity, so the accuracy of the instrument is still guaranteed after a long time.
4. Perfect protection function. When there is an overvoltage, overcurrent, or high voltage short circuit, the instrument can quickly cut off the high voltage, and send a warning message. A warning message is issued when the temperature sensor fails or is not connected.
5. The limited temperature relay is set in the medium frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay will be released and the heating will stop.
6. Convenient setting of test parameters. The temperature ranges from 40 ° C to 120 ° C and the AC voltage ranges
7. 200 to 2200V. The DC voltage ranges from 0 to 500V.
8. Using a large screen TFT pure color LCD touch display, the display is clear. With a simple setup, the instrument can be tested automatically. And automatically store and print test results.
9. With a real-time clock, test date and time can be saved, displayed, and printed with the test results.
10. Empty electrode cup calibration function. The capacitance and dielectric loss factor of the empty electrode cup are measured to judge the cleaning and assembly condition of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculation of relative capacitance and DC resistivity.
11. The instrument takes the RAM9 platform as the core, with high test accuracy and fast speed
