数字化电能表现场校验技术分析

Analysis of Field Verification Technology for Digital Energy Meter

数字化电能表是科技进步的产物,很多智能变电站都开始使用这种电能表来统计电能。但是,由于该类电表刚刚开始投入使用,还没有一套系统的校准方法和使用规范,在运用中存在许多不足。为了满足变电站的需求,已经有科学家研究出了针对这一类电表的校准方法了。笔者主要研究了数字化电能表产生误差的原因,并对目前使用较多的三种校准方法进行了比较。希望可以给变电站以及相关部门提供参考。

Digital energy meter is the product of scientific and technological progress, many intelligent substations are beginning to use this energy meter to count the power. However, due to the type of meter has just begun to put into use, there is no system of calibration methods and the use of norms, there are many deficiencies in the use. In order to meet the needs of substations, scientists have developed a calibration method for this type of meter. The author mainly studies the reason of the error of the digital energy meter, and compares the three calibration methods which are currently used more, Hope to give the substation and the relevant departments to provide reference.
