1. A method of operating an electrostatic precipitator, comprising the steps of intermittently feeding the precipitator with electric power according to a cycle comprising a controlled preset ON-time interval and a preset OFF-time interval in order to apply to the precipitator electrodes a cyclic time-varying voltage, monitoring the electrode voltage and establishing a voltage peak value and a voltage mean value, multiplying the established peak value with the established mean value to compute an index of expected performance (IEP), effecting successive incremental time variations of said ON-time interval and repeating the steps of monitoring and multiplying so as to establish a correlation of said index to said time variations, establishing a time value of said ON-time interval corresponding to a maximum of said index, and selecting said established time value as a new set point for said ON-time interval.
