Abstract
A capacitor including an expandable part fabricated on a capacitor housing is enclosed. The expandable part is expandable by a fault that occurs within the capacitor housing, thereby extending the capacitor housing to contact with an external interrupter. The external interrupter includes an external electrode and an external sensing circuit. The external sensing circuit detects a contact between the capacitor housing and the external electrode and sends a signal to disconnect the capacitor from an apparatus circuit.
