Abstract :
Two novel techniques are described to predict arcing in switch mode power supplies used in large computer systems. One technique, called the partial vacuum test, can be used to determine locations susceptible to arcing. The second technique, called the zinc spray test, can help determine the minimum spacing between features, subjected to high voltages with high frequency harmonics, that will avoid arcing in the field
