Abstract
Propagating brush discharge testing systems may include a dielectric layer, an initiation electrode, a high-voltage switch, an optical sensor, and a controller. The initiation electrode has an exposed tip positioned adjacent to a surface of the dielectric layer. The high-voltage switch is configured to selectively isolate the initiation electrode from ground potential. The optical sensor is positioned and configured to sense light generated at the surface due to a propagating brush discharge. The controller is programmed to operate the high-voltage switch to ground the initiation electrode and to operate the optical sensor to collect light from the propagating brush discharge. Propagating brush discharge testing methods include positioning an exposed tip of an initiation electrode with respect to a surface of a dielectric layer, then charging the surface, and then grounding the initiation electrode to neutralize charge on the surface (generally causing a propagating brush discharge).
