Summary:The paper reports the results of experimental study of the self-healing efficiency on metal-film capacitor elements with an all-over metallization. The characteristics of the self-healing have been obtained for capacitor elements made of polypropylene, polyethylene terephthalate, polyphenylene sulfide with zinc metallization and polyimide with aluminum metallization. The effect of electrode resistance on the efficiency of self-healing has been experimentally investigated for zinc metallized polyethylene terephthalate films with square resistance ranging from 2 to 85 Ohm. The parameters of the self-healing process affecting its efficiency were determined. The insulation resistance degradation kinetics of the of metallized polymer films due to inefficient self-healing acts was obtained. The polypropylene film was found to be superior over the other studied films in terms of the efficiency of self-healing.
