The KDYD-GY power frequency overvoltage protection test device is safe, reliable, easy to use, and easy to maintain. It is mainly used to conduct overvoltage tests on various electrical products, electrical components, insulation materials, etc. under specified voltages, and measure the ability of overvoltage. It is a product that requires overvoltage testing equipment for power operation related departments, electrical equipment manufacturing enterprises, metallurgy, coal mining, electrified railway related departments, scientific research units, and higher education institutions.

1. Industrial touch screen display of data such as voltage, current, time, status information, and form information, with clear and intuitive readings;
2. Chinese interface, simple and clear operation, suitable for various application scenarios;
3. Set the output voltage directly through touch screen buttons, start with one click, and automatically complete the test;
4. During the experiment, there is a clear voltage display on the screen, constantly reminding operators to pay attention to safety;
5. Automatic timing function, during automatic control, when the voltage automatically rises to the set value, the device automatically starts timing, and when the timing time is up, the device automatically returns to zero position;
6. Manual control mode, similar to traditional electric up/down mode, is controlled by touch buttons, and the device automatically determines the upper/lower limit with overvoltage protection;
7. Intelligent control of boost speed, when the voltage reaches 80% of the target voltage, the boost speed will automatically slow down, and when it reaches 90% of the target voltage, the boost speed will further slow down;
