IEC, ASTM Standards 60, 75, 80, 90, 100 Kv Transformer Oil Dielectric Breakdown Voltage Tester

HZJQ-N1 60, 75, 80, 90, 100 Kv Transformer Oil Dielectric Breakdown Voltage Tester is used for testing dielectric strength of insulating oils used in transformers and circuit breakers. It is fully automatic micro controller based system, completely self-contained and compact. It gives smooth and continuously electronically controlled test voltage from 0 up to 60, 75, 80, 90 or 100 kv, with no distortion of waveform. It meets IEC156/IS6792/ASTM D1816/ASTM D877/ UNE 2. And it is of fully automatic operation with a built-in printer to print test results.

Key Function And Feature

1. With a microprocessor, automatically fulfill the withstand voltage test for oil circulation with a range of 0～ 100KV (including boosting, maintaining, mixing, standing, calculation, printing and other operations).

2. Display by large-screen LCD and prompt by English 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 6 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 and displaying current ambient temperature and humidity.

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. （Optional）
