AC and DC Flash Testing
For the test between the primary circuit and an accessible section as shown in Fig. B-2, an AC voltage is normally applied. If a filter for eliminating the electromagnetic interference is present in the location corresponding to Z1 or Z2 and its capacitive component is large, the distinction between the current flowing through the filter and the current used to assume a dielectric breakdown will be difficult. In this case, it is recommended that the test be performed using a DC voltage equal to the peak value of the specific AC voltage.
