Abstract

1. A process for continuously optimising the electric working point of an electro-static wet filter (4) connected to an alternating current network (N apprch) by means of an electric setting element (1), characterised in that at pre-determined time intervals the control of the setting element (1) is automatically modified in an interative manner until the mean value of the measured direct filter voltage (UFm ) lies at the achievable maximum of this mean value, that an operating point is determined therefrom, wherein the mean value of the direct filter voltage (UFR ) lies a predetermined percentage below the voltage maximum (UFM ) - when the direct filter current (JF ) is increased compared with this operating state - and that this percentage is automatically changed in dependence upon the measured dust loading of the pure gas and/or the absorbed electric power of the filter (4).
