Tips: The Differences Between AC Hipot Test and DC Hipot Test
The DC hipot test can effectively find the overall defects such as insulation moisture and dirt, and can find the local defects of the insulation through the relationship between current and leakage current. Since the DC voltage is divided by the insulation resistance, the end insulation defect can be found more effectively than the AC. At the same time, due to DC voltage.
The insulation does not substantially cause dielectric loss, and therefore, DC hipot test is less destructive to insulation. In addition, since the DC withstand voltage only needs to supply a small leakage current, the required test equipment has a small capacity and is convenient to carry.
The AC hipot test is performed at 2.5 times or more of the voltage of the device under test, and from the viewpoint of thermal breakdown of the dielectric loss, the weakness of the local free defect and the insulation aging can be effectively found. Since the voltage is divided mainly by the capacitance at the alternating voltage, the insulation defects of the device can be effectively exposed. However, the AC hipot tester is more destructive to insulation than DC, and since the test current is a capacitor current, a large-capacity test equipment is required.
