Abstract

Experimental investigations conducted on a large number of experimental model samples made with polypropylene film and impregnated with SF₆ are reported. Samples and experiments were designed to identify and highlight the effects of critical factors, such as electrode material and configuration, winding tension, gas filling pressure, and impregnation cycle, on the partial-discharge behavior of the samples. It is noted that the results could serve as useful design data for the design of SF₆-filled high-voltage equipment using polypropylene film in particular and any plastic film in general
