Oil BDV Tester

Many power systems, railway systems, large-scale petrochemical plants and enterprises have a lot of electrical equipment whose internal insulation are mostly oil-filled insulation type, and therefore, test on insulating oil dielectric strength is common and necessary. To meet the needs of the market, we have developed and produced a series of insulating Oil BDV tester according to national standard IEC 60156:1995, industry standard DL429.9-91 and the latest Electric Power Industry Standard DL/T846.7-2004 by ourselves. This instrument, by using a single-chip microcomputer as the core, can operate in full automation with high accuracy, greatly improving work efficiency and reducing the labor intensity of workers. Moreover, Oil BDV tester is small in size and convenient to carry.

1. With a microprocessor, automatically fulfill the withstａnd voltage test for oil circulation with a range of 0～80KV (including boosting, maintaining, mixing, standing, calculation, printing and other operations)

2. Display by large-screen LCD and prompt by Chinese menu

3. Simple operation. The Oil BDV tester will automatically complete the withstａnd voltage test on one cup of sample oil after simple setting by the operator. Breakdown voltage value of 1 to 9 times and recurrent times will be automatically saved. After the test, the thermal printer will print each breakdown voltage value and average value.

4. Power-down preservation. It can save 100 tested results.

5. Adopt a single-chip microcomputer to boost the voltage at an even speed. The voltage is accurate at 50HZ, ensuring the whole process easy for control.

6. Equipped with over-voltage, over-current and limit protections to ensure the safety of operators.

7. With the function of displaying the measured temperature and system clock.

8. Communicate with computer with a standard RS232 interface.

9、USB， can export the test data.

1. Preparation before Test

① Connect the earth terminal (on the right side of the equipment) to the earth wire firmly before start the equipment.

② Sample the oil according to relevant standard. Adjust the electrode distance inside the oil cup with standard gauge. Clean the cup according to relevant requirements. Pour the sample into the cup and close the cap.

③ Switch on AC220V power supply after the above items are confirmed, ready for the test.
