New Energy Sources WhatsAppIntroduction. Self-healing is the spontaneous extinction of a local electrical arc due to the destruction of the electrodes during the process. It occurs in capacitors made of metallized films of plastics with a thin layer of metal (the layer thickness e is ∼10 nm).This phenomenon was first studied by Heywang and Kammermaier [1], [2].
