The influence factors of capacitor leakage current size


The discretion of the dc voltage (1), has obvious effect on leakage current size; When the applied voltage is less than the rated voltage, leakage current slow rise with the increase of the applied voltage, when the applied voltage exceeds the rated voltage, leakage current will be risen dramatically.
(2) general electric capacity of capacitor itself, the greater the leakage current is bigger (the same raw material and manufacturing process).
(3) in the initial stages of applied voltage, leakage current increased with the increase of applied voltage duration drops rapidly, finally reached a stable value.
(4) leakage current as temperatures rise by exponentially.
(5) foil oxide film and other related materials, processing technology
6. The purity of raw materials, especially in the high working temperature, the effect is more significant.
All landowners electrolyte to repair the oxide film and the ability to prevent the deterioration of oxide film.
