摘要

变压器绝缘纸板绝缘材料中含有过高的水分

会加速变压器的老化

还会带来绝缘性能下降等危害

因此测试变压器绝缘纸的水含量十分必要。本文主要介绍一种综合采用极化—去极化电流和频域（变频）分析对变压器进行含量水量测试的方法

并列举现场应用实例

应用结果证明该方法的实用性。

Abstract

The relatively high moisture in oil-paper insulations will accelerate cellulose aging and decrease the dielectric withstand strength

so it is very necessary to measure moisture content.A new moisture content measurement method is introduced in this paper

adopting polarization and depolarization current method and frequency domain spectroscopy method.Application examples are presented and the result proves the method is practical.
