Abstract

Aging and degradation of high voltage insulation due to applied and environmental stresses are being studied in order to predict the performance of high voltage equipment in space. Results will be presented on surface flashover measurements on commercially available polymers which have been stressed by exposure to vacuum, d.c. electric fields, and pulsed electric fields. A newly developed analysis technique using laser excited fluorescence (LEF) has been applied to analyze damage caused by flashover and aging. LEE allows analysis, on a molecular scale, of chemical and structural changes with a sensitivity much greater than previously possible. Data will be presented on the degradation due to aging before flashover occurs, as well as damage caused by flashover events.
