Does dielectric breakdown have a physical indication?

[bhope691]

I have a capacitor which I would like to know if the dielectric has undergone dielectric breakdown. Is there anyway I can tell without specialist equipment, is there physical damage to the material that I can see with the naked eye?

The material is quartz.

Thanks.

Dear,

you should try read IEC 60243-2-2001 standard, test for dielectric breakdown voltage.

A quartz capacitor? You don't mean mica? Can you attach a photo of the capacitor?

As a generalisation, I would expect that dielectric damage is not always going to be obvious.

Even if he means a crystal it´s also a capacitor ツ + Yes, it can be seen by naked eye. Mica as Quartz too gets fine fissures or breaks even through when dielectrical damaged.
