In the Reliability and Quality Engineering Test Laboratory at the NASA Lewis Research Center a nondestructive, corona-vacuum test facility for testing power system components was developed using commercially available hardware. The test facility was developed to simulate operating temperature and vacuum while monitoring corona discharges with residual gases. This facility is being used to test various...
Corona testing has been used to screen high voltage magnetics for reliability, despite the fact that the significance of the measurement results is not well understood. This paper examines the fundamental physics involved, and displays a method of determining correct corona specifications.
Common test methods specified for high voltage components are compared with nondestructive test techniques which yield quantitative data related to the reliability and life expectancy of the insulation system. Equipment and test set ups are discussed and measured results analyzed.
One easily overlooked aspect of electronic design is partial discharges and voltage breakdown at low gas pressures. On many occasions in the space program equipment losses from partial discharges and voltage breakdown have resulted in only partial mission successes. This rap session on high voltage electronics is intended to give design engineers an opportunity to exchange information on causes of...
