Abstract��In order to increase the usage and prolong the lifespan of power capacitors, failure analysis on power capacitors is very important and necessary. The traditional measuring method is voltage and current meters or dual voltage meters. Compared with that��digital meters such as AI-6600 which are used to measure the capacitor value mostly, which have the advantages of wider range and higher accuracy. Through analyzing the data, which are accumulated from one group of 12 capacitors running between 2003 and 2011, bulky harmonic current and higher temperature in the circumstance are the main reasons to make the power capacitor fail in the rolling line. The feasible preventive maintenance to restrain harmonics current was offered and the temperature was improved,making the on-time monitoring come true.
