Introduction:
- 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 dielectric strength testers according to national standard IEC156, 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, an operate in full automation with high accuracy, greatly improving work efficiency and reducing the labor intensity of workers.
Technical Specifications:

- Standing time: 15min (adjustable)
- Boosting interval: 5 min (adjustable)
- Boosting frequency: 1~9 time(s) (optional)
- Booster capacity: 1.5KVA
- Measuring accuracy: ±3%
- Supply voltage: AC220V±10% 50Hz±1 Hz
- Power: 200W
- Applicable temperature: 0ºC~45ºC
- Applicable humidity: <75%RH
- Overall dimension: 465×385×425
Characteristics:
- 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).
- Display by large-screen LCD and prompt by Englishmenu.
- 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.
- Power-down preservation. It can save 100 tested results and displaying current ambient temperature and humidity.
- 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.
- Equipped with over-voltage, over-current and limit protections to ensure the safety of operators.
- With the function of displaying the measured temperature and system clock.
- Communicate with computer with a standard RS232 interface.
