Abstract

Process and device for visually checking the soiling level of an electrostatic filter fed by a high-voltage transformer 4, some of the rectified current of which is tapped at the high-voltage output in the form of a return voltage. The visual indication 30 is obtained by a continuous measurement of the return voltage which is directly linked to the soiling level of the electrostatic filters. <IMAGE>
