Self- healing is the ability of a metallized capacitor to clear a fault area where a momentary short occurs due to dielectric breakdown under voltage. The conditions that lead to a fault vary. In the production of the dielectric film, contamination can occur or a process control problem can result in compromised dielectric strength.
Abstract: 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.
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].
To achieve such performances, metalized film capacitors (MFC) are adopted. Comparing with conventional liquid impregnant capacitors, the high energy density of MFCs is derived from the self-healing properties of metalized film.
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.
