摘要：Method and arrangement for establishing a change in the level of dust extracted in one of a plurality of precipitator units incorporated in an electrostatic dust precipitator (1) which comprises a multiple of sequentially connected precipitator units (A, B, C, D) provided with separately controllable current and/or voltage supply circuits and which further comprises an inlet (5) for receiving a flow of dust-contaminated gas and an outlet (5a) for discharging a flow of gas which has been cleansed of dust to a given extent. Changes in the level of dust extraction in the aforementioned one unit (a) are evaluated on the basis of occurrent changes in the current and/or voltage values of a unit (B, C or D) located downstream of the one unit (A).
