Abstract
Gap current is sensed and a voltage signal representative of gap current is integrated to provide a relatively stable DC voltage that is proportional to average current at the gap. A reference setting is made to which the average gap current is compared and, responsive to rise in current above that level, cutoff of the power supply will be initiated.
