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.
The breakdown happens in metallized polypropylene film (MPPF) capacitor can be classified into two cases: the first one is self-healing, which means that the insulation will recover after the ...

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. Meanwhile, the reported theoretical and experimental results have …
A theory of self-healing (SH) in metallized film capacitors is introduced. The interruption of the filamentary breakdown current in the thin dielectric insulation occurs when the thermally driven increase of the series impedance in the electrode metallization destabilizes the breakdown plasma arc. The interruption process can be described as a …
Besides, because of their excellent self-healing characteristics, electrical characteristics, high speed of charging and discharging, metallized film capacitors are widely used in electronic power equipment, such as electronic ballasts, power electronic converters and ...

When self-healing fails, the intermittent electric arc will lead to potential hazards, such as fire or explosion of the capacitor and endanger the safety of the power grid [4]. Therefore, self-healing failure should be avoided to the highest extent.
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, …
The breakdown happens in metallized polypropylene film (MPPF) capacitor can be classified into two cases: the first one is self-healing, which means that the insulation will recover after the breakdown; the other one is self-healing failure, which means that the capacitor will fail because of short-circuit fault. In this paper, the MPPF capacitor applied …
The electric-field stess in metallized film capacitors may be much ger than in film foil lar capacitors. This is obtained thanks to the ability of the electrodes to self-heal. If a breakdown occurs in the polymer, the current will increase through the defect and on the

Benefiting fromself-healing features, metallized film capacitors (MFCs) are widely employed to compensate reactive power (VAR) and thus improve the performance of AC systems.
The proper design of the electrode segmentation guarantees the best efficiency of the capacitor''s self-healing (SH) ability. Meanwhile, the reported theoretical and experimental results have not led to the commonly accepted model of the SH process, since the experimental SH dissipated energy value is several times higher than the …
