摘　　要：简述 TYD1 1 0 /3— 0 .0 2 H型电容式电压互感器的工作原理 ,结构及在电力系统中所起的作用 ,通过在电力系统运行中所出现的瞬间失压故障 ,应用常规试验方法和特殊试验手段所测得数据 ,综合分析判断 。The operating principle, structure and function of type TYD110/√3-0.02H capacitive voltage transformer are described. It is shown that fault detection of sudden loss in voltage for the CVT can be performed using the conventional method in combination with special means of testing. Based on the comprehensive analysis of the measured data, the fault location can be accurately determined. Problems to be noticed in detection are also discussed.
