The thin metallization on the polymer films gives these metallized thin film capacitors a unique self-healing property. In the event of a localized breakdown of the dielectric, the energy that is discharged is capable of locally vaporizing the metallization and re-establishing isolation between the two electrodes [4].This self-healing characteristic …

The metalized film capacitor can work under a high electric field due to its self-healing characteristic. Firstly, this study indicates that inter-layer air is one of the most important factors which influence the process of self-healing. The interlayer air not only increases the duration of self-healing process, but also increases the self-healing energy and self …
