The Role Of Recoverable And Non-Recoverable Defects In Dc Electrical Aging Of Highly Disordered Insulating Materials, Allen Andersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Electrical insulation under high voltage can eventually fail, causing critical damage to electronics. Such electrostatic discharge (ESD) is the primary source of anomalies or failures on spacecraft due to charged particles from the Sun or planetary radiation belts accumulating in spacecraft insulators. High-voltage direct current power distribution is another example of a growing industry that needs to estimate the operational lifetime of electrical insulation. My research compares laboratory tests of ESD events in common insulating materials to a physics-based model of breakdown. This model of breakdown is based on the approximation that there are two primary types of defects in …
