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.

The DC working voltage is the maximum DC voltage and NOT the maximum AC voltage. A capacitor with a DC voltage rating of 100 volts DC cannot be safely used to an AC voltage of 100 volts. This is because an alternating voltage that has an RMS value of 100 volts will have a peak value over 141 volts (√2 x 100).
