Application Scenarios
The AC Withstand Voltage Tester is an instrument specifically designed to perform withstand voltage tests on electrical equipment. Some electrical equipment is marked with its rated voltage when it leaves the factory. However, in actual use, the voltage of electrical equipment in the power grid system often fluctuates, and sometimes it may operate beyond the rated voltage. If the electrical equipment cannot withstand the high voltage for a short period of time and fails, it can lead to the complete paralysis of the power grid. In dangerous situations, it can cause fires and electric shocks. Therefore, it is crucial and necessary to perform withstand voltage tests on electrical equipment before it leaves the factory.

FAQ
Q: What does the AC Withstand Voltage Tester come with?
A: Test transformer, control box, matching test leads, instruction manual, test report, and packing list.
Q: What operations are required before connecting the power?
A: First, adjust the voltage regulator on the control box (table) to the zero position. After connecting the power, the green indicator light will illuminate. Press the start button; the red indicator light will illuminate, indicating that the transformer is energized and ready to step up the voltage.
Q: What happens if the leakage current is too high during testing?
A: When the leakage current is too high or the test object breaks down, the overcurrent protection relay will quickly cut off the power.
