摘要

在线检测变压器高压套管的介质损耗是判断其绝缘状况的有效手段。笔者通过与套管末屏串联的分压电容提取工频电压信号

采用绝对测量和相对测量相结合的方法准确地测量了套管的介质损耗

并应用传输线理论分析了其误差特性。现场运行证明

该方法是有效的。

Abstract

On-line monitoring the dielectric loss of power transformer bushing has been proven to be effective tool in evaluating the condition of its insulation. The measured signal is abstracted from capacitor

which is in series with the bushing tap. In this paper

the absolute and relative methods are combined

and the phase error in transmission process is analyzed based on transmission line theory. Field monitoring result shows that this method is effective.
