AC vs DC fuses, High Current, Explosive Destructive Testing and Theory

This is a introduction to the differences between AC and DC fuses. I also use a high voltage / current discharge capacitor for a destructive test of the two difference fuses. You should also check out how ingenious high voltage fuses are made in this article Teardown of a medium voltage fuse (7200 V / 200 A).
