| Abstract: | Based on the phenomenon of the emerging faults in shunt capacitors,an on-line fault monitoring system is introduced,and the characteristics and functions are analyzed.The system is of the function of monitoring practical current and voltage signals on-line by Labview programming;the harmonic wave,overvoltage,and close inrush current can be analyzed in the system.What′s more,a typical fault of a capacitor due to breakdown is discussed in this paper.By this original data the further study on shunt capacitors can be supplied. |
