Prevention of Electrical Breakdown in Spacecraft

The methods for preventing electrical breakdown problems in space flight are discussed. The techniques that have been evolved by several successful users of high-voltage systems in space are given in considerable detail. The fundamental elements are the avoidance of high electric fields and the avoidance of critical gas pressures. Selection of materials, scrupulous cleanness, good mechanical design, solid potting or complete venting, and frequent testing are the major steps to success.
