AC Withstand Voltage Test Device
Product Introduction:
The AC Withstand Voltage Test Device is a test equipment designed by Yangzhou Haode Electric Co., Ltd. according to the national industry test standards. It is safe, reliable, powerful, easy to use, and simple to maintain. It is mainly used for insulation strength tests under specified voltages on various electrical products, electrical components, insulating materials, etc., to assess the insulation level of products, discover insulation defects of test objects, and measure the ability to withstand overvoltage. It is a * product for power operation related departments, electrical appliance manufacturing enterprises, metallurgy, coal mines, electrified railway related departments, scientific research institutions, and colleges and universities that need withstand voltage test equipment.
* This device occupies small space and is light in weight, making it very suitable for on-site testing;
* Safety protection is very reliable, with an execution time of 1 microsecond during overcurrent, overvoltage, discharge, overheating, and zero-start conditions.
* This device has passed strict test appraisal by the national authoritative department - Electric Power Industry Electrical Equipment Quality Inspection and Testing Center (Wuhan High Voltage Research Institute), with reliable quality, ensuring the safety of test personnel, test objects, and the test equipment itself;
* Meets national standard requirements: has monitoring peak/√2 function, can monitor test waveforms in real-time;
* One-key mouse-style knob "foolproof" operation, large screen LCD display;
* Unique software calibration function, convenient for users to calibrate meters, ensuring accuracy of high voltage values
* The device comes with a built-in micro printer, which can promptly print and save test data;
Precautions:
1. Since most resonant power supply equipment are high-voltage test equipment, it is required that high-voltage test professionals must carefully read the instruction manual before use and undergo repeated operation training.
2. The number of test operators must not be less than 2. During operation tests, the safety operation procedures for high-voltage tests of the unit must be strictly implemented.
3. To ensure the safety and correctness of the test, in addition to being familiar with this product manual, national standards and procedures for test operation must be strictly followed.
4. All connecting wires must not be connected incorrectly, especially the grounding wire. Otherwise, it may cause damage to the test device.
5. When using this device, it outputs high voltage or ultra-high voltage, and must be reliably grounded, paying attention to safe operating distance.

Product Features
1. Voltage, current, time, status information, and prompt information are displayed on a 4.7-inch large screen LCD, with clear and intuitive readings;
2. Full Chinese interface, simple and clear operation, adaptable to various application occasions;
3. Light-touch key operation, all functions can be set through keys, improving product safety and reliability;
4. Fully digital calibration method, abandoning outdated potentiometer adjustment, extremely convenient for on-site use, and easy to control accuracy (this function is password protected);
5. Keys directly set the test transformer ratio (this function is password protected), allowing flexible application when connecting testers of different voltage levels, truly achieving one control box can be matched with multiple transformers;
6. Status reminder function, full Chinese guided operation, can be skillfully operated even without the manual;
7. During the test, a flashing high-voltage symbol is displayed on the screen, constantly reminding operators to pay attention to safety;
8. Test result display function, can automatically judge test results (test passed or failed), and reliably record the voltage at overcurrent, flashover, or breakdown of the test object;
9. Test result sound alarm function, when the test passes or fails, the device will emit different alarm sounds, and test personnel can directly identify the test result from the alarm sound;
10. Pause function, in automatic control mode, this function can achieve pause of voltage rise or fall at any point, and the pause time can be flexibly controlled by test personnel, convenient for observing the state of the test object
11. Automatic timing function, in automatic control mode, when the voltage automatically rises to the set value, the device automatically starts timing, and when the timing time is up, the test result is displayed, and the device automatically returns to zero
12. Manual timing function, in manual control mode, the timer can be started manually, and when the withstand voltage time is up, the device automatically returns to zero (only desktop devices have this function);
13. Manual control mode, this mode is similar to traditional electric raise/lower voltage method, with rise/fall controlled by buttons, the device automatically judges upper/lower limits, and has overvoltage protection;
14. Intelligent control of voltage rise speed, when the voltage reaches 80% of the target voltage, the rise speed automatically slows down, and when it reaches 90% of the target voltage, the rise speed further slows down;
15. Optional remote communication, door interlock alarm light and bell, external voltage divider calibration interface, etc.;
16. Adopts combination of hardware and software anti-interference technology, with stable performance and strong anti-interference capability.
