摘要

在综合研究局部放电的各种统计特征参数的基础上

将金融时序分析方法引入局部放电

提取了一种基于平均放电量与放电次数的综合特征参数——放电量放电次数趋势（PVT）

相比其它的特征参数

PVT能够更清晰地显示局部放电的发展趋势并揭示出变化过程中存在的异常现象。文中通过两个具体的应用实例

对PVT参数的性能进行了验证

初步的研究结果表明

PVT能为局部放电的严重程度评估提供有效的支持。

Abstract

Based on various statistical parameters extracted from partial discharge

in the contribution

by introducing the financial time sequence analyzing method

a novel parameter indicating the development trend of partial discharge

namely partial discharge-volume-trend

is proposed.PVT can display and discover the abnormal case in the partial discharge developing process more clearly in comparison to other parameters of PD.For validating the performance of PVT

two practical applications are analyzed.Results obtained demonstrate that PVT can provide promising support for the evaluation of partial discharge.
