Abstract

Corona tests were run on three prototype avionics connectors intended for use in a 270-V direct-current aircraft electrical system. The corona performance was evaluated in an altitude simulation chamber. The control parameters for the testing included pressure, temperature, and applied voltage. A sophisticated test stand was developed to provide control of pressure gradients to better simulate airframe mission profiles. Test results indicate that gas desorption or outgassing from insulating surfaces subjected to pressure excursions may play a major role in the level of discharge activity
