How to discharge something through dielectric?

[Stanley514]

If I have some increased electric charge in some material which is surrounded by dielectric,
what could be a way to discharge it?Let`s say, I can`t penetrate a dielectric with grounded metal probe.

Then obviously you'll have to discharge it THROUGH the dielectric, however slow that might be.

Is this a trick question?

All materials have an electrical breakdown limit.
Even non-conductiong materials are mode of atoms.
When the electric field exceed a certain limit, some electrons for these atoms can run away and initiate a breakdown.
