Analysis of the Fault in 66 kV High Voltage Shunt Capacitors

LIANG Yi-ming1,SHI Ming-biao2(1.Jilin Province Electric Power Research Institute,Changchun 130021;2.Shanxi Yangcheng International Power Generating Co.,Ltd,Jincheng 048000,Shanxi,China)  
According to a fault of 66 kV high voltage shunt capacitors in one power substation,this paper analyzes some aspects such as,product design parameters,product technology quality,product structure and material quality,external fuse,and so on.It can be found that the fault is due to the synthesis of insulating deficiency of some products,definite value of relay protection,and quality of external fuse.Furthermore,the fault causes are concluded based on synthesis analysis,and suggestions are put forward in order to avoid similar faults.
