Creative Technology Provider Capacitor main defect factor Below table is showed a capacitor main defect factor. Points Defect factor Over-voltage In case of capacitor ambient temperature is higher than permission ambient temperature Using environment -> High voltage power capacitor -20℃ ~ 40℃ -> Low voltage power capacitor -25℃ ~ 45℃ Dust sticking Arc by bad contact, abnormal noise Over heat by loose wire connection Unsuitable interval in parallel installation Incongruence installation Over capacity(over leading) Differential with series reactor capacity Switch incongruence Radiation from heating element of transformer and series reactor Abnormal voltage Surge voltage from lightning, circuit breaker, switch Short and grounding fault in system Very frequently used for make and break Treatment Make and break in short time(re-input minimum time) - High voltage power capacitor : more than 5 min - Low voltage power capacitor : more than 3 min External cause Construction cause Contact with small animal and conductivity material Oil leakage Early defect by using material Nature trouble Shorten life ※ If you need a further information, Please contact to technical division.
