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 capacitor 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 acknowledgement and pecaution.
