Parameter setting instructions:

Boost speed adjustment difference: During automatic testing, when there is still a difference of this value from the target voltage, it switches from fast to slow speed；

Upper and lower limits of voltage regulation error: Refers to the need to automatically control the voltage regulation to be within this range when it is outside of this range；

Jogging delay count: an internal parameter of the system that cannot be changed；

Flashover protection:Protection voltage during breakdown. The smaller the value is set, the more sensitive the breakdown protection becomes, and sometimes it may cause misoperation. In general, when the highest voltage of the device is lowYu150kVWhen settingfor3kVWhen the maximum voltage of the device is lowYu150~300kVWhen settingfor5kVWhen the maximum voltage of the device is lowYu300~500kVWhen settingfor8kVWhen the maximum voltage of the device is lowYu500~800kVWhen settingfor12kVThis value is a theoretical value and can be set according to on-site needs；

Serial port settings: The serial port used by the industrial computer；

High voltage: The high voltage required for the test sample；

Instrument voltage: Instrument winding voltage of transformer；

Periodic experiments can be set up, up to a maximum ofplace9Only the first five stages are displayed in the report.

After setting the parameters for each stage, click the save button, and then the experiment can directly click the import button to import the previously saved parameters.

4-2-4Turn on the emergency stop switch,clickThe contactor is closed and the system startsautomaticboostAt the same time, it is also necessaryPay close attention to the high-voltage display window, and the system will start timing when the voltage reaches the first stage target value， Start boosting after reaching the specified time until reaching the second stage target value（If there is only one stage, the target voltage will automatically drop after reaching the specified value）When the last stage of withstand voltage time is reached, the system begins to reduce voltage until the regulator returns to zero position.

4-2-5 After the experiment is completed, the system automatically saves the experimental data and generates a report. ClickButton, select, clickButton, the system automatically pops up all test report records, such asimage5：
