HM801 Transformer Oil Dielectric Strength Tester

Transformer Oil Bdv Tester,
Oil Breakdown Voltage Tester,
Oil BDV Tester, Transformer Oil Tester.

Product Description


Transformer oil bdv tester is designed and researched by our technical based on the IEC60156  requirement. It is one fully automatic testing instrument. In order to satisfy different client's requirement, we design single-cup and three -cup. The instrument is easy to operate and beautiful in appearance. Adapted the use of automatic digital microcomputer control, the measurement accuracy is high, anti-interference ability is strong, safe and reliable.


  1. With a microprocessor, automatically fulfill the withstand voltage test for oil circulation with a range of 0~80KV/100kV(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 machine 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.
