Abstract : Seven prototype connector boards were tested at Wright Laboratory in the Aerospace Power Division High Power Lab. Each connector board incorporates two types of connectors: (1) ac/dc hybrid connector with six power feedthroughs, i.e. two for dc power and four for ac power, and (2) dc connector with two power feedthroughs. The 270 volt dc rated power feedthroughs were tested with 500 volts dc. The three phase, 208 volt ac (line-to-line) power feedthroughs were tested with 354 volts ac rms. The boards were tested at ground level and at simulated altitudes of 50,000 and 100,000 feet. Corona data acquisition was accomplished in accordance with ASTM 1868-81, using a multichannel analyzer for discharge magnitude characterization. The boards performed well with only insignificant corona activity above five picocoulombs.
