Product Introduction

YDJ-350KVA 350KV Power frequency AC Hipot test system

In high-voltage power systems, the power frequency withstands voltage testing system plays a crucial role in ensuring the safety and reliability of equipment. It can test the insulation strength of various electrical products, electrical components, insulating materials, etc., evaluate the insulation level of the products, identify insulation defects of the tested items, measure the ability to withstand overvoltage, effectively detect potential safety hazards in electrical equipment, prevent accidents, and ensure the stable operation of the power system.

Wuhan Huayi Electric Power is a professional manufacturer of power frequency test systems, which are researched and made based on IEC standards, widely used for power systems, electric companies, and the power industry.

Product Feature And Application

1. Using a high-resolution 7-inch high-brightness full-color PLC touch display (resolution 800 × 480), voltage, current, time, status information, and prompt information. All in the large-screen LCD, with clear and intuitive reading.

2. Full English interface, simple and clear operation, can adapt to a variety of applications;

3. High-precision touch screen operation, all functions can be touched to improve the safety and reliability of the product;

4. All-digital calibration method, abandoning the old potentiometer adjustment, the field is very convenient to use, and the accuracy is easy to control (this function with password protection).

5. Directly set the test transformer ratio (this function with password protection). When connecting testers of different voltage levels, the application is flexible and free; truly, a console/box can be used with multiple transformers.

6. State reminder function, full English guided operation, even in the absence of instructions, can be skillfully manipulated.

7. During the test, there is a display in progress on the screen to remind the operator to pay attention to safety.

9. Sound and light alarm functions can be activated when the test results are abnormal.

11. Automatic timing function. During automatic control, when the voltage automatically rises to the set value, the device automatically starts timing. When the time is up, the test result is displayed, and the device automatically returns to the zero position.

13. Manual control mode, this mode is similar to the traditional electric lift/step down mode, the button controls the rise/fall, the device automatically determines the upper / lower limit, and there is over-voltage protection.

14. The boosting speed is intelligently controlled. When the voltage reaches 80% of the target voltage, the boosting speed will automatically slow down. When the target voltage reaches 90%, the boosting speed is further slowed down.

15. It combines hard and software anti-interference technology, with stable performance and strong anti-interference.

16. With the printing function, you can quickly print the test data and test date.

17. USB transfer function, you can save the saved test data to the USB flash drive to make a long-term backup.
