摘要
三相不平衡度是电能质量的一项重要指标,其测量仪器各种各样,越来越多,但校准设备几乎空白。本文介绍一种用于检定三相不平衡度仪表的数字式校验台,文中在对校验台的测量不确定度分析的同时,提供了实测的结果。
This paper presents a new digital calibration equipment for instruments mea-suring three-phase unbalance factor.The calibration principle,the system configuration,the performance consideration,the operation process and primary specification is intro-duced,and discusses the measurement uncertainty in calibration.
