摘　　要：主要描述了临海站220kV电容式电压互感器(CVT)在正常运行中出现B相二次输出电压较低的故障现象,进而从红外测试、停电试验数据、解体检查等方面进行综合分析,指出了故障原因。This article mainly described the failure of which the secondary output voltage of phase B of a 220kV capacitor voltage transformer （CVT） was lower than the required value under normal operation. Through synthetic analysis, such as using infrared detection, the failure reason was found.
