ABSTRACT:
The operation of one or more full-size electrostatic filters for removing solid impurities from gaseous carrier media is regulated automatically as a function of variations of breakdown potential of a miniature electrostatic filter which is installed in the path of the contaminated gaseous carrier medium. The regulation is such that the potential which is applied to the corona discharge electrode(s) of the full-size filter(s) is very close to but continuously below the breakdown potential. This eliminates the periods of idleness of the full-size filter(s) by preventing arcing because the applied potential does not reach the breakdown value at which the electrostatic field collapses.
