摘要
文中阐述了电能计量装置进行期间核查的方法,重点介绍了基于休哈特Shewhart控制图的期间核查方法。并以三相电能表检定装置的期间核查方法为例,对测量数据进行定量分析,进而判定三相电能表检定装置的可靠性。实验证明,此方法切实可行,能有效地保证装置检定或校准状态的置信度。
This paper is introduced the period verification on the electrical energy measuring equipments. In particularly,the method of the period verification based on Shewhart controlling graph is proposed. For the period verification on the three-phase electrical energy meter verification equipment,as an example ,the measured data were analyzed. The reliability of the equipment is proved. It indicates that the method of the period verification is feasible. The believable state of the measuring result is ensured effectively.
