Abstract
In an electric field curtain system, a plurality of linear electrodes are embedded in an insulator layer in parallel to each other along the surface of said insulator layer so that silent discharge forming curved electric lines of force which are outwardly convex may be produced on the surface of said insulator layer, the width of each of said plurality of linear electrodes is chosen equal to or less than 3 mm, and the interval between the respective linear electrodes is selected within a limited range, whereby every charged particle may be floated away from the surface of the insulator layer so as not remain on said surface.
