What does self-healing in film capacitors mean?

Self-healing characteristics of metallized film capacitors: When the metallized film capacitor breaks down due to the existence of a bottle point in the dielectric, an arc current will be generated immediately at the breakdown point, and this current density is concentrated at the middle point of the breakdown. Due to the thinness of the metal layer, the heat generated by this current is sufficient to melt and vaporize the metal near the breakdown point. A metal-free area is formed to restore the insulation between the capacitors, so that the capacitors can resume normal operation. The capacitance of the capacitor will decrease slightly after self-healing, but generally it will not affect the normal work.
