Many power systems, railway systems, large-scale petrochemical plants and enterprises have a lot of electrical equipment which 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 GB/T507-2002, industry standard DL429.9-91 and the latest Electric Power Industry Standard DL/T846.7-2004 / IEC-60156 / ASTM1816 / ASTM D877 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, it is small in size and convenient to carry. Fast delivery I 24-hour customer service I customizable Major Technical Indicators 1.Output voltage: 0~80KV (optional) 2. Voltage distortion rate: <3% •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) • Large screen color LCD display, touchable, Chinese and English interchangeable menu prompts; With beautiful appearance, small size. •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 10 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. •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. (Optional) •USB, can export the test data.
