According to the power capacitor configuration and fault data of the device within Jiangsu power grid

the defects of 35 kV power capacitor are analyzed deeply from such aspects as the cause

position and occurrence time of the defects of the capacitor

the rule is summarized.The main reason for the fault is due to aging of the device and such position as lead joint

fuse

capacitor proper and string resistance are those with frequent defect occurrence and the fault for the devices operating over 10 years have many defects.Finally

the suggestion and measures are proposed from such aspects as device purchasing

installation and commissioning

operation&maintenance and repair so to improve operation reliability of the capacitor.
