摘要

传统概念认为电容式电压互感器（CVT）的高频传变性能差

不能满足暂态行波信号的传变要求。本文通过借鉴变压器的波过程理论

构建CVT的仿真模型

并对CVT的高频暂态特性进行仿真分析。结果表明CVT能够有效传变高频暂态信号的波头部分

其二次侧信号可用于行波定位。

Abstract

Traditional concept for capacitor voltage transformer（CVT）is that it has poor performance in transferring high frequency signal and can not meet the need of traveling wave signal.On the base of drawing the wave theory of the transformer

CVT simulation model was constructed and the CVT transient characteristics of high frequency was analyzed in the article.The results show that the CVT can effectively transfer the high-frequency transient signals

and the secondary wave signal can be used in fault location.
