Many power utilities, generation companies, railway substation, large-scale petrochemical plants etc. 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 & necessary.
To meet the needs of the market, we have developed and produced a series of common and necessary. insulating oil dielectric strength testers according to national standard IEC156. This instrument, by using a single-chip microcomputer as the core, an operate in full automation with high accuracy.
Key Features
- 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
- 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
- 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.
