In power systems, railway systems, large-scale petrochemical plants and enterprises there is 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 international standard IEC60156,national standard GB/T507-2002, 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, 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.


1,The instrument adopts microprocessor, which can automatically complete the operation of boosting, maintaining, stirring, static discharge, calculation and printing, and can conduct oil cycle withstand voltage test within 0-80kv range.
2. Large screen color LCD, touch, Chinese and English exchange menu prompt; Beautiful appearance and small volume.
3. The instrument is simple to operate, and the operator only needs to set it. The instrument will automatically complete the pressure test of one cup of oil sample according to the setting. The breakdown voltage and cycle times of 1-10 times will be stored automatically. After the test is completed, the thermal printer can print out the breakdown voltage value and average value of each time.
4. The instrument test implementation standard includes industry standard, national standard and foreign standard, and it is easy to operate.
5. The power is kept, and 100 experimental results can be stored.
6. The voltage frequency is accurate to 50Hz by using single chip microcomputer control to boost the voltage at a uniform speed, which makes the whole process easy to control.
7.  It has protection of over voltage, over current and limit position to ensure the safety of operators.
8.Standard RS232 interface, can communicate with computer.

9. USB interface, which can export test data.
