NASA-HDBK-4007 (Baseline 2016-10-27) w/Change 3, SPACECRAFT HIGH-VOLTAGE PASCHEN AND CORONA DESIGN HANDBOOK, Revalidated (2020-12-29). Active. Scope: This NASA Technical Handbook presents an overview of high-voltage electrical/electronic design techniques required to specify and apply electrical insulation to spacecraft high-voltage parts, components, and systems. Of particular interest are spacecraft system designs that are needed to meet stringent fault-free operation for a period of days to years in space without maintenance. The first objective is to develop an understanding of electrical insulation characteristics and the influence of aging. A second objective is to capture decades of lessons learned and present recommended design, analysis, and test methodologies that have been applied to the many successful space vehicle electronic programs during their development, manufacture, final assembly, test, and flight.
