This instrument is designed and manufactured in accordance with the national standard GB/T507-2002 and the electric power standard DL429.9-91. It is suitable for testing the degree of physical contamination of insulating oil by water and other suspended substances, and is widely used in industries such as electric power, petroleum, and chemical engineering.

Main features:

1. Controlled by a microprocessor, with three cups integrated, it automatically completes operations such as voltage boosting, maintaining, stirring, standing, calculating, and printing. It can perform oil circulation withstand voltage tests within the range of 0-80KV.

2. The instrument will automatically complete the withstand voltage test for 1-3 oil samples. After completion, it can print out the breakdown voltage values and average values of each oil sample for each test.

3. It has power-off retention function, can store 100 test results, and can display the current ambient temperature and humidity.

4. It adopts a single-chip microcomputer to control the uniform voltage boosting, and the voltage frequency is accurately 50HZ, making the whole process easy to control.

5. It is equipped with overvoltage, overcurrent, and limit protection to ensure the safety of operators.

6. Standard RS232 interface, which can communicate with computers.
