  • Method for monitoring the signal quality of an electrostatic precipitator and electrostatic precipitator
    Patent number: 10864527
    Abstract: The method for monitoring the signal quality of an electrostatic precipitator comprises measuring in real time at least one feature of a primary electric power sent to a transformer of the electrostatic precipitator and/or at least one feature of a secondary electric power sent to the collecting electrodes and discharge electrodes of the electrostatic precipitator, elaborating the at least a measured feature generating an information indicative of the electrostatic precipitation signal quality, providing the information.
