Self-healing low-voltage capacitors often experience capacity reduction after practically operating for a certain duration.Most of the capacitor components can be appropriately switched-off upon protection actions,and in severe cases,some components get breakdown or even burning.In view of this the present work carried out dissection of core connec-tions and component metallization films with respect to damaged capacitors,and a series of corresponding tests such as square resistance and film thickness on the components wound with metallized films.As a result the methods of enhancing the metallized films of self-healing low-voltage capacitors have been put forward.
