摘　　要：推导并建立了电容分压型电子式电压互感器(ECVT)的传递函数模型,分析了ECVT频率特性及正常测量频率范围,重点研究了其对多种暂、稳态扰动信号的测量性能。研究结果表明:在正常测量频率范围内,ECVT可对多种暂态扰动信号及国标中所要求的谐波信号进行准确测量,具有良好的一次信号还原性能。The transfer function model of ECVT（electronic capacitive voltage transformer） is deduced and established. Both the frequency characteristic and the normal frequency domain of ECVT are analyzed; meanwhile, the measurement performance of ECVT for various transient and steady-state disturbance signals is studied in details. Research results show that, within the normal measuring frequency domain, variety of transient disturbance signals as well as harmonic signal required in national standard could be measured accurately by ECVT, and ECVT has excellent restoration capacity for primary signal.
