  • Product 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 GB/T507-2002, industry standard DL429.9-91 and the latest Electric Power Industry Standard DL/T846.7-2004 by ourselves. This transformer tester is based on single-chip microcomputer, fully automated operation, high precision, greatly improving work efficiency and reducing labor intensity of workers.

  • Product Features
1. With a microprocessor, three cups of a body, 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. This transformer tester has the advantage of simple operation. The operator only needs to set it up easily, and the instrument will automatically set according to 1-3 oil sample pressure test. For each oil sample, each breakdown voltage value and number of cycles are automatically stored. After the test is completed, the thermal printer can print the breakdown voltage value and the average value.
4. Maintain power down, can store 100 experimental results, and can display the current environment temperature and humidity.
5. The transformer tester adopts single-chip microcomputer to control the speed regulation, and the voltage frequency precision reaches 50HZ, which makes the whole process easy to 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.
