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.
Metallized film capacitors have an ability to withstand the breakdown of dielectric film due to a “self-healing” feature. The optimal design of metallized electrodes' patterns guarantees high… Owing to the property of self-healing, metalized film capacitors can be reliably used under high electric field.
Owing to the property of self-healing, metalized film capacitors can be reliably used under high electric field. However, self-healing is at the expense of capacitance loss. Therefore, it is of great… Metallized film capacitors (MFCs) are used in many applications requiring high volumetric energy characteristics.
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.
Provided by the Springer Nature SharedIt content-sharing initiative Policies and ethics Metalized film capacitors (MFC) are widely applied in power system, military weapons and railway traffics, etc. The lifetime of MFC is closely related to the self-healing (SH) process, which causes the loss of electrode area and thus leads to the capacitance...
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.
