Voltage rating tells us the maximum voltage the capacitor can withstand while functioning correctly. For capacitors with capacitance greater than 100 µF, we can often find their value written directly on it (a 200 µF 25 V capacitor has a capacitance of 200 µF and works with voltages up to 25 V ).
Therefore, if we use dc test voltage, we ensure that the dc test voltage is under root 2 (or 1.414) times the ac test voltage, so the value of the dc voltage is equal to the ac voltage peaks. For example, for a 1500-V-ac voltage, the equivalent dc voltage to produce the same amount of stress on the insulation would be 1500 x 1.414 or 2121 V dc.
