Repeated withstand tests are destructive to the EI transformer itself
Many times of withstand voltage test, the insulation of the ei transformer itself is very destructive, for most of the transformers will gradually reduce the insulation effect of the transformer, of course, there will be a small part of the mutation of direct withstand voltage NG. The reason is the same as in the first answer: each time the withstand voltage will not be the absolute leakage current is 0, as long as there is a leakage current, it means that there is a "dew point", and after the leakage current, this "dew point" will gradually increase, until the leakage current reaches the limit, and there is an alarm, poor voltage resistance.
