Main failure Mechanism of Capacitor Open Circuit.
(1) The "self-healing" occurs in the lead position, making the electrode insulates from the lead wire;
(2) The contact surface of the outlet line and the electrode is oxidized, resulting in low level open circuit;
(3) Poor contact between the lead line and the electrode;
(4) Corrosion fracture of anodic elicited foil of electrolytic capacitor;
(5) Electrolyte drying or freezing on the liquid table;
(6) Dielectric instantaneous open circuits under mechanical stress.
