INSULATION AGING BEHAVIORS CHARACTERIZED WITH DIELECTRIC THERMAL ANALYSIS (DETA)
Abstract
Navy technology goals continue to include more efficient, power-dense, and cost effective electric machinery. Wide bandgap power electronic modules will be utilized in power drives to achieve improved performance. High frequency switching of voltage and/or current in electric machinery may accelerate insulation aging, along with thermal and mechanical stresses. This collaborative effort will document aging in thermoset polymers used in electrical insulation for power-dense machinery as related to rheological changes. New and emerging thermoset polymer materials are emphasized. A second objective is to publicly present the utility of Dielectric Thermal Analysis (DETA) and the supporting science to encourage wide use of the tool within the electric power community. A published compendium is anticipated in textbook format.
