Voltage resistance test of Capacitor DC power supply(II)

The advantage of DC withstand voltage test is that when the equipment to be tested is sufficiently charged, only the real leakage current will flow through. This makes the DC withstand voltage tester clearly appear the leakage current of the equipment to be tested. Because the charging current is temporary, the power condition of the DC voltage tester is generally much smaller than the power condition of the AC voltage tester used to test the same product. The DC power withstand voltage tester will charge the capacitor. If the AC power supply is used to withstand voltage, DC will not have a simulated environment.
