Abstract

The invention relates to a circuit configuration for the suppression of arcs in a plasma wherein to the plasma path (5, 7, 8) a voltage (11) is applied. The instantaneous value of the voltage of the plasma path (5, 7, 8) is compared with a mean value of the voltage which has been determined over a given period of time. If the difference between the instantaneous value and mean value exceeds a given amount, the plasma path (5, 7, 8) is isolated from the voltage (11).
