Reassessing Self-Healing in Metallized Film Capacitors: A Focus …
Metallized film capacitors (MFCs) are known for their self-healing (SH) properties, enabling efficient and reliable operation, even under challenging conditions. These SH events have the potential to inflict damage on both the polypropylene (PP) film and the electrode layer. However, not all types of SH damage lead to catastrophic failure of the capacitor. Thus, …
