Method and apparatus for testing fastener arcing and sparking.

摘要

A method and apparatus for testing arcing and/or sparking of a fastener (16) installed in a carbon fiber composite (CFC) panel (10). The fasteners (16) are installed in a test panel (10) which is attached to a light-tight enclosure including a camera (24). Current is injected to the fasteners (16) through current injection tabs (18) attached to each of the fasteners (16) from the outside of the enclosure. As the current level injected from a current source is varied, the camera (24) records images of the manner in which electrical arcing and/or sparking occurs between the fastener (16) and the test panel (10).
