THE ELECTROSTATIC FIELDS AND DISCHARGE HAZARDS OF INSULATING SHEETS CLOSE TO A CONDUCTOR - A REVIEW

Dielectric sheets and films are used in various forms in a large numbe r of industrial applications, The important electrostatic properties o f such sheets are reviewed to highligbt the significance of the surfac e potential, the electric held within and adjacent to the sheet, and t he electric energy stored. Selected industrial examples in the fields of electrophotography, electrostatic painting, and materials handling are discussed, A case study of a specific industrial problem involving charge retention on plastic boxes treated in an ac corona discharge i s described.
