In this paper the arc voltage of a vacuum interrupter, switching a 10 A DC current, is evaluated. Voltage peaks are counted during 6 ms and represented in histograms. These histograms are unambiguously discriminative for pressures above 3*10/sup -2/ Pa. Beyond this pressure a sharp change in the performance of the arc voltage is visible.
