A Brief Introduction to the Self-healing of Metalized Film Capacitors …
There are two different mechanisms for self-healing of metalized film capacitors: one is discharge self-healing; the other is electrochemical self-healing. The former occurs at higher voltage, so it is also referred to as high-voltage self-healing; because the latter also occurs at very low voltage, it is often referred to as low-voltage self-healing.
