A significant increase in the efficiency of modern metallized film capacitors has been achieved by the application of special segmented nanometer-thick electrodes. The proper design of the electrode segmentation guarantees the best efficiency of the capacitor's self-healing (SH) ability.

Self-healing (SH) in metallized polypropylene film capacitors (MPPFCs) can lead to irreversible damage to electrode and dielectric structures, resulting in capacitance loss and significant stability degradation, especially under cumulative SH conditions.
At this point, the polymer absorbed oxygen and generated insulating materials, which isolated the defective portion from the remainder of the capacitor. Despite the loss of some effective capacitance, the self-healing process had a negligible impact on the overall performance, while substantially reducing the LC [40, 41].
During self-clearing of metallized film capacitors, there is a gradual decrease of capacitance as a result of an increasing number of self-clearing events, which eventually leads to catastrophic breakdown of the capacitor; for example, see Figure 4 B.
RP serves as a valuable tool for evaluating the safety of MFCs with an unknown SH history, contributing to the assessment of their reliability. Metallized film capacitors (MFCs) are known for their self-healing (SH) properties, enabling efficient and reliable operation, even under challenging conditions.
Capacitors made of metallized polypropylene films suffer partial discharges, called self-healing, due to weak electrical defects. Those defects are destroyed by an electrical arc that extinguishes when enough metal of the electrodes is vapourized around this point.
