Self-Healing in Metallized Film Capacitors: Theory of Breakdown …
A theory of self-healing (SH) in metallized film capacitors is introduced. The interruption of the filamentary breakdown current in the thin dielectric insulation occurs when the thermally driven increase of the series impedance in the electrode metallization destabilizes the breakdown plasma arc. The interruption process can be described as a …
