Application Scenarios
In power grid systems, AC Hipot Testers are used to perform withstand voltage tests on some electrical equipment in advance using the power frequency. The power frequency is the closest to the grid voltage and is also the frequency that best reflects the actual operating state of electrical equipment. This allows for the early detection of defects in electrical equipment, preventing damage to some main equipment in the power grid caused by insufficient withstand voltage levels, which could lead to a series of accidents. In particular, tests must be performed after the production of electrical equipment, project handover, and major maintenance. This can effectively detect defects such as moisture absorption, aging, air gaps, and mechanical damage in the insulation of electrical equipment.

FAQ
Q: How to operate the control box after the test?
A: After the test, the voltage regulator should be adjusted to zero at a constant speed.
Q: What should I do if the voltmeter pointer swings wildly during the test?
A: If the ammeter reading increases sharply, or if the test sample smokes, arcs, shows signs of burning, or makes abnormal noises, immediately reduce the voltage, disconnect the power supply, and check the cause.
Q: What should be done during DC testing?
A: During DC testing, a current-limiting resistor and a filter capacitor should be added to prevent damage to the silicon stack. Discharge should be performed using a discharge rod after the test.
