Skylab high voltage systems corona assessment

During the Test and Integration phase of the NASA Skylab space vehicle it was recognized that the high voltage equipment and experiments used for electronic sensing and power generation, could be corona susceptible. Some of those spacecraft sensors and circuits were found to be sensitive to very low-level signals such as produced by partial discharges or corona. A massive discharge such as a corona burst or arc could degrade some of the information or malfunction a circuit. Therefore it was deemed necessary to determine which experiments and equipment aboard Skylab were susceptible to the partial discharges or corona and establish by test and analysis their threshold of corona susceptibility.
