摘要：

The first single partial discharges under ramp voltage are investigated in submillimetric air gaps and nonuniform field. Several polymer films with different thicknesses are used as a dielectric barrier: 12- and 100-mu m polyethylene terephthalate films, 28-mu m polyimide film, 6- and 12-mu m polypropylene films. The inception voltage (breakdown voltage) and the discharge current are registered. The parameters of the accumulated surface charges measured by a rotating capacitive probe are presented. The surface charge patterns obtained by means of the dust figure method are shown. Probable mechanisms of the discharge development are discussed.
