HK-507A Insulating Oil Breakdown Voltage Tester

Overview
The HK-507A Insulating Oil Breakdown Voltage Tester complies with the requirements of the GB/T 507, DL 429.9, and DL/T 846.7 test methods. It is suitable for determining the dielectric strength of insulating oil filled in electrical equipment in power systems, railway systems, and large-scale petrochemical plants and mines.
Functional Features

1. The tester adopts a microprocessor to automatically complete operations such as voltage boosting, holding, stirring, standing, calculation, and printing. It can perform oil circulation withstand voltage tests within the range of 0～80kV.
2. Equipped with a large LCD screen and Chinese menu prompts.
3. The tester is easy to operate; operators only need to make simple settings to complete the test and obtain results.
4. Supports power-off data retention, can store 100 test results, and can display the current ambient temperature and humidity.
5. Uses a single-chip microcomputer to control uniform voltage boosting, with the voltage frequency accurate to 50Hz, making the entire process easy to control.
6. Equipped with overvoltage, overcurrent, and limit protection to ensure the safety of operators.
7. Has temperature measurement and display functions, as well as system clock display.
8. Standard RS232 interface for communication with computers.
