并联电容器的电容值是反映电容器设备状态的关键指标，电容器内部个别电容元件的损坏会导致其他元件承受过电压而击穿损坏，而内部电容元件的损坏会在电容器电容值上反映出来，通过对电容器组电容值的实时计算可以实现对电容器组的在线监测。并联电容器的放电线圈一般都有二次绕组，从二次绕组可以获取电容器两端的电压，利用电容器两端的电压和电流数据可完成对电容器组电容参数的计算，从而实现对并联电容器健康状态的实时获知和预警。

The capacitance of the shunt capacitor is a key indication reflecting condition of capacitor , damaged individual compenents in the capacitor will cause other compenents breakdown ,the damage of internal capacitor will be reflected in the capacitance of capacitor ,online monitoring of capacitor bank can be achieved through real time calculation of capcitance of capacitor bank .The discharge coil of shunt capacitor bank has in general secondary winding ,from which the voltage across the ca-pacitor can be obtained ,the capacitance parameter calculation of capacitor bank can be completed by the use of voltage and current data on both ends of capacitor ,thus achieving real time acknowledge-ment and pecaution .
