摘要

当电力系统中存在雷击或操作过程时

其高频暂态过电压会以静电感应和电磁耦合的方式从高压系统传递到低压系统

会对二次系统的测量装置、保护装置以及二次设备本身和运行造成严重的影响。本文通过对比电容式电压互感器（CVT）暂态过电压响应特性的试验研究和仿真分析

对高频过电压在CVT中的传递特性作了一定的探讨和分析

并对响应试验和仿真过程遇到的问题作出了归纳总结

为过电压在线监测等工作提供了参考。

Abstract

In case of lightning or operation process in the power system

its high-frequency transient overvoltage can be transferred from high voltage system to low voltage system by the electrostatic induction and electromagnetic coupling mode

which will cause serious influence on the measurement and protection device of secondary system

the secondary equipment itself and operation. In this paper

the transfer feature of high frequency overvoltage in CVT is discussed and analyzed by way of comparison of test and simulation analysis of transient overvoltage response characteristic of capacitor voltage transformer（ CVT）

and the problem encountered during response test and simulation is summarized

which provides reference for such works as overvoltage online monitoring.
